I am working on a sharepoint 2013 on-premises team site. now i want to set a column which is of type date/time to be equal to today date,so i added a script inside the Edit form, then i tried to set the date value using SPUtiltiy, as follow:- ``` var today = new Date(); var dd = today.getDate(); var mm = today.getMonth()+1; //January is 0! var yyyy = today.getFullYear(); if(dd<10) { dd = '0'+dd } if(mm<10) { mm = '0'+mm } today = dd + '/' + mm + '/' + yyyy; alert(today); SPUtility.GetSPFieldByInternalName('OrderDateCustomerApproved_').SetValue(today); ``` but i got this error:- ``` Unable to set date, invalid arguments (requires year, month, and day as integers). throw "Unable to set date, invalid arguments (requires year, month, and day as integers)."; ``` so i tried to do so using pure JavaScript appraoch as follow:- ``` $('select[id^="OrderDateCustomerApproved_"]').val(today); ``` where this did not raise any error, but the field was not populated with today date!! so can anyone adivce on this please?

I use the following piece of code to set value to Date-time field with SPUtility and jQuery ``` var currentDate = new Date(); $(SPUtility.GetSPFieldByInternalName(internalFieldName).Controls).find('input').first().val((currentDate.getMonth() + 1) + '/' + currentDate.getDate() + '/' + currentDate.getFullYear()); ``` My Site collection uses `MM/DD/YYYY` format for dates so i'm setting it in that format. You will have to change the format if needed.

I was working on something similar last week. Maybe this will point you in the right direction. ``` <script> 'use strict'; (function() { var timeSinceFieldViewCtx = {}; timeSinceFieldViewCtx.Templates = {}; timeSinceFieldViewCtx.Templates.Fields = { "Time": { /* Change to your Date Column - Same as below */ "View": timeSinceFieldViewTemplate } }; SPClientTemplates.TemplateManager.RegisterTemplateOverrides(timeSinceFieldViewCtx); })(); function timeSinceFieldViewTemplate(ctx) { var dateDiff = new Date() - new Date(ctx.CurrentItem.Time); /* Change to your Date Column */ var daysDiff = Math.floor(dateDiff / 1000 / 60 / 60 / 24); return daysDiff; } window.addEventListener('DOMContentLoaded', function() { var x = document.getElementsByClassName('ms-vb-lastCell'); for( var i =0; i < x.length; ++i ) { console.log(x[i].innerText + " Type Of: " + typeof Number(x[i].innerText)); if (Number(x[i].innerText) > 30 ) { x[i].style.color = 'green'; x[i].style.fontWeight='normal'; } if (Number(x[i].innerText) > 60 ) { x[i].style.color = 'green'; x[i].style.fontWeight= 'bold'; } } }, true); </script> ```

SharePoint adds a format function to a date object, so you can use that to do your formatting as well. And I don't used the ID of the field, I use the title because that makes things easier to read. ``` $("input[title='Date Customer Approved']").val(today.format('MM/dd/yyyy')); ```

I ran and configure the key and the rest with `aws configure` But when I run `eb init` I got the error > > ERROR: 'init/20160618/us-west-2/elasticbeanstalk/aws4\_request' not a valid key=value pair (missing equal-sign) in Authorization header: 'AWS4-HMAC-SHA256 Credential=eb init/20160618/us-west-2/elasticbeanstalk/aws4\_request, SignedHeaders=host;x-amz-date, Signature=95e3...56e4'. > > > `Awsebcli` and `Python` should be set up correctly with version `EB CLI 3.7.6 (Python 2.7.1)`. Can someone help me figure out why?

You have to remove or edit the file **config** on the occult directory named .aws, this directory usually is in C:/User/{Your user}/.aws or unix /User/{Your user}/.aws

I encountered the same issue with the same error message, I solved the issue by adding "aws\_access\_key\_id" and "aws\_access\_key\_id" inside both "config" and "credentials" files inside ~/.aws/ directory.

I have a javascript function that adds text to an asp:textbox. But once I try to save the textbox in the C# Codebehind, the textbox.Text property is still holding the original value, not the updated value. Here's the code Javascript ``` function GetLanguages(e) { var newLang = e.nextSibling; var checkedValues = ''; var chkEng = document.getElementById ("<%=chkEnglish.ClientID %>"); var chkFr = document.getElementById ("<%=chkFrench.ClientID %>"); var chkList1 = document.getElementById ("<%=chkTopLanguages.ClientID %>"); var arrayOfCheckBoxes = chkList1.getElementsByTagName("input"); var txtLangValue = document.getElementById("<%=txtLANG.ClientID %>"); if(chkEng.checked) checkedValues = "English"; if(chkFr.checked) { if(checkedValues.length > 0) checkedValues += ";"; checkedValues += "French"; } for(var i=0;i<arrayOfCheckBoxes.length;i++) { var checkBoxRef = arrayOfCheckBoxes[i]; if(checkBoxRef.checked) { var labelArray = checkBoxRef.parentNode.getElementsByTagName('label'); if ( labelArray.length > 0 ) { if ( checkedValues.length > 0 ) checkedValues += ";"; checkedValues += labelArray[0].innerHTML; } } } txtLangValue.value = checkedValues; } ``` CodeBehind ``` List<string> lstItemsChecked = new List<string>(txtLANG.Text.Split(';')); foreach (string language in lstItemsChecked) { foreach (DataRow row in dsTopLanguages.Tables[0].Rows) { if (row["Language"].ToString() == language) { if (strLanguages.Length > 0) strLanguages += ";"; strLanguages += row["LanguageID"].ToString(); } } } ``` The txtLANG.Text.Split call results to the original value of the textbox, not the value updated via javascript

uggh, figured out what was wrong. Long day, way over complicated things. I forgot to wrap my data load code with if(!IsPostback){} so it was reloading the original record data before saving the values to the database. Sorry!

And you are sure that the javascript function is being called and that the textbox is getting its value updated? Have you tried adding the following at the end of your JavaScript function to make sure the value of the text box is being updated? ``` alert(txtLangValue.value); ```

In your main activity, assuming your fragment has an ID called R.id.details, ``` HomeFragment f = (HomeFragment)getFragmentManager().findFragmentById(R.id.details); if(f != null) { f.refresh_data(); } ``` You can assign an ID to a fragment in your XML layout file.

But In order to crete a simple accordion, the I must increment `id="tab1">` because in each loop, so my idea was to ditch `@foreach` and use `@for` loop, so I can make use of the `key` to increment the value of `id="tab1">` Hope it makes sense

```cs result = JsonConvert.DeserializeObject<PullRequestModel>(responseData); @for (var key = 0; key < result.value.Count; key++) { } ``` *List<>* exposes the **Count** property not **Length** property.

It would appear you are deserializing a single object and not an enumerable type. Please try using the following if you want to return something to loop through: ``` result = JsonConvert.DeserializeObject<List<PullRequestModel>>(responseData); @for (var key = 0; key < result.Count; key++) { } ``` Count is a property of of the List object in this case.

As per the other question, this is the only "clean" way to do it currently. The cleanest way to approach things in Wordpress is by using filters and/or actions - this allows you to interact with core without making changes *in* core. By tapping into filters/actions you are also giving *other* plugins the chance to operate on the filter/action arguments before/after your hook. If you take a look at `class-wp-rest-server.php` you can easily look at all available filters and actions related to rest. You will notice this one in particular: ``` /** * Filters the array of available endpoints. * * @since 4.4.0 * * @param array $endpoints The available endpoints. An array of matching regex patterns, each mapped * to an array of callbacks for the endpoint. These take the format * `'/path/regex' => array( $callback, $bitmask )` or * `'/path/regex' => array( array( $callback, $bitmask ). */ $endpoints = apply_filters( 'rest_endpoints', $this->endpoints ); ``` From my research, this is the very last spot to modify (remove, change or add) endpoints, and is the exact purpose of the filter. As a sidenote, you don't need to do it "one by one" - you *could* just do `$endpoints = []` to start fresh.

I recently had to disable member-only content from appearing in the REST API. Instead of filtering the rest endpoints, I filtered the args used to register the post types: ``` function dbdb_unset_rest_routes( $args, $post_type ) { $allowed_post_types = array( 'page', 'post', 'company', 'job' ); $allowed_post_types = apply_filters( 'dbdb_unset_rest_routes_types', $allowed_post_types ); if( in_array( $post_type, $allowed_post_types ) ){ return $args; } else { $args['show_in_rest'] = 0; } return $args; } add_filter( 'register_post_type_args', 'dbdb_unset_rest_routes', 20, 2 ); ``` The REST API calls `get_post_types()` in `create_initial_rest_routes()` and looks for any post types that have `show_in_rest` set to `true`. By filtering the args via the filter: `register_post_type_args` in `register_post_type()`, we can filter these routes from showing up in the API.

This question has already accepted answer. But if anybody find this useful. We can easily remove default routes. Add following code in your theme's (child theme's if any) functions.php or in any custom plugin ``` add_filter('rest_endpoints', function( $endpoints ) { foreach( $endpoints as $route => $endpoint ){ if( 0 === stripos( $route, '/wp/' ) ){ unset( $endpoints[ $route ] ); } } return $endpoints; }); ```

This code ```js alert("Hello again! This is how we" + "\n" + "add line breaks to an alert box!"); ``` doesn't work. Firefox JavaScript console names error as "unterminated string literal" and points on " symbol before \n. I want to fire an alert with multi-line text. No jQuery please.

2012/02/18

Question is old but I want to give a clear answer and explain why this happens for others who comes here: First of all, there is nothing wrong with the JavaScript code line in the question. It is absolutely valid and produces no parsing error. The reason for the problem in Vitalmax' case was most likely because he/she didn't posted additional code, which surrounded that line. Here is an example in PHP, which shows why the JS parser complains about the syntax: ``` <?php echo "alert('Hello again! This is how we\nadd line breaks to an alert box!');"; ?> ``` The parsed server-side output then is (this is what the browser gets): ``` alert("Hello again! This is how we add line breaks to an alert box!"); ``` In JavaScript, strings **must not** have real line breaks.\* Instead, they must always be escaped (like: \n), so the browser complains about an "unterminated string literal" at the real line break. There are some exceptions to this rule, like for horizontal tabulators (\t). So (in this case) you have to escape the line breaks twice with \\n. So when PHP parses and converts it from \\n to \n, JavaScript can convert it from \n to *[real line break]*. Correct PHP example would be: ``` <?php echo "alert('Hello again! This is how we\\nadd line breaks to an alert box!');"; ?> ``` Or: ``` <?php echo 'alert("Hello again! This is how we\nadd line breaks to an alert box!");'; ?> ``` In the second case you don't have to double escape it because escaped characters within PHP strings with single quotes are not decoded (\n stays \n). \*Note: It is possible to use the special quote sign ` which allows real line breaks in JS. Example: ``` alert(`Hello again! This is how we add line breaks to an alert box!`); ```

I had issues where \n and \n didn't work, then I tried using html break tag i.e. since that panel was written in html and it worked. example - ``` some text here <br> some more text ``` output: ``` some text here some more text ```

This code ```js alert("Hello again! This is how we" + "\n" + "add line breaks to an alert box!"); ``` doesn't work. Firefox JavaScript console names error as "unterminated string literal" and points on " symbol before \n. I want to fire an alert with multi-line text. No jQuery please.

Adding changing `\n` to `\\n` should work if you are rendering the alert serverside (ie: On a website), but if you are running client side (ie: testing etc.) just `\\n` will not work work. For example, try running the following lines on [this](http://jsfiddle.net/) website. ``` alert("Hello again! This is how we"+"\n"+"add line breaks to an alert box!"); ``` or: ``` alert("Hello again! This is how we" +"\\n" +"add line breaks to an alert box!"); ``` In jsfiddle, the first one works, because it runs it client side, but if you are running it serverside, it requires the double slash (`\\n`) I'm not sure why this is, but I have tested it multiple times. Hope this helps!

This script works for me. ``` <script> alert("Hello. \r\n How are you?"); </script> ```

alert("Hello again! This is how we" + "\n" + "add line breaks to an alert box!"); \n --> this is working [working with \n](https://i.stack.imgur.com/aoQhV.png) \n --> does not work, it just treat it as continuous string of alert msges [does not working with \n](https://i.stack.imgur.com/tmMVi.png)

Another way is using `String.fromCharCode()`: ``` alert("This unit has been removed from stock" + String.fromCharCode(13) + " Do you wish to RETURN this unit to stock?"); ```

Haven't tested but does this work? ``` alert("Hello again! This is how we \n add line breaks to an alert box!"); ```

`error "missing ; before statement"` That tells me the semicolon is missing from above this line of code. Usual syntax gotchya are if statements that don't close parentheses properly. Or curly braces.

This code ```js alert("Hello again! This is how we" + "\n" + "add line breaks to an alert box!"); ``` doesn't work. Firefox JavaScript console names error as "unterminated string literal" and points on " symbol before \n. I want to fire an alert with multi-line text. No jQuery please.

Haven't tested but does this work? ``` alert("Hello again! This is how we \n add line breaks to an alert box!"); ```

A more functional way i would suggest is to define your own `print()` function and forget about putting `\\n` for each line manually ```js //define var print = new Function("var lines=arguments[0]+'\\n';; for(var i=1;i<arguments.length;i++){lines+=arguments[i]+'\\n';} alert(lines);"); //call print("say","hello","to","javascript","this","is ","awesome"); ``` Now you may call the `print()` with multiple arguments and each argument will be available in a separate line.

This is how we\nadd line breaks to an alert box!');"; ?> ``` The parsed server-side output then is (this is what the browser gets): ``` alert("Hello again! This is how we add line breaks to an alert box!"); ``` In JavaScript, strings **must not** have real line breaks.\* Instead, they must always be escaped (like: \n), so the browser complains about an "unterminated string literal" at the real line break. There are some exceptions to this rule, like for horizontal tabulators (\t). So (in this case) you have to escape the line breaks twice with \\n. So when PHP parses and converts it from \\n to \n, JavaScript can convert it from \n to *[real line break]*. Correct PHP example would be: ``` <?php echo "alert('Hello again! This is how we\\nadd line breaks to an alert box!');"; ?> ``` Or: ``` <?php echo 'alert("Hello again! This is how we\nadd line breaks to an alert box!");'; ?> ``` In the second case you don't have to double escape it because escaped characters within PHP strings with single quotes are not decoded (\n stays \n). \*Note: It is possible to use the special quote sign ` which allows real line breaks in JS. Example: ``` alert(`Hello again! This is how we add line breaks to an alert box!`); ```

Use single quotes. ``` alert("Hello again! This is how we"+'\n'+"add line breaks to an alert box!"); ```

**Preface** I've just started getting into Ruby and try to not only learn the language but also some development strategies. As kind of a beginner I'm concentrating on Test and Behaviour Driven Development. (yes, I'm doing both for comparison purposes) With my small software project I'm using * UnitTest (TDD) * Cucumber (BDD) * Rspec (TDD and BDD) On various places I encountered RCov as a tool for telling me how much of my actual code I'm really testing. I set up the following RakeTask in my `Rakefile` for the covarage analysis of the UnitTests: ``` desc "Run RCov to get coverage of UnitTests" Rcov::RcovTask.new(:rcov_units) do |t| t.pattern = 'tests/**/tc_*.rb' t.verbose = true t.rcov_opts << "--html" t.rcov_opts << "--text-summary" t.output_dir = "coverage/tests" end ``` This works fine and I'm getting a nice coloured HTML report in `coverage/tests`. **Problem Introduction** Similar I wrote the following RakeTasks for RCov to be used for coverage analysis of my specs: ``` desc "Run RCov to get coverage of Specs" Rcov::RcovTask.new(:rcov_spec) do |t| t.pattern = 'spec/**/*_spec.rb' t.verbose = true t.rcov_opts << "--html" t.rcov_opts << "--text-summary" t.output_dir = "coverage/spec" end ``` **Problem Definition** However, the generated HTML report in `coverage/spec` looks somehow incomplete and almost failed. None of the tested method bodies are marked as covered and thus red. However, I'm 100% sure they are executed within the specs.

Make sure that you are requiring rcov early enough. From <http://rubydoc.info/github/relevance/rcov/master/Rcov/CodeCoverageAnalyzer>: > > Note that you must require 'rcov' before the code you want to analyze is parsed (i.e. before it gets loaded or required). You can do that by either invoking ruby with the -rrcov command-line option or just: > > >

I fixed this by adding: `RSpec::Core::Runner.autorun` to the bottom of my spec file; worked even with rspec 2.9

I've got similar trouble. I am 100% sure that specs are not executed when I run them win RCov. But they do when I disable RCov. Downgrading RSpec to version 2.6.0 helped me.

I'm sure this is a pretty universal question, but I somehow can't find any info on it online. I have an e-commerce site with different product prices. I then use Javascript to calculate the total price, but where exactly should I store each pricing value to avoid getting hacked? One tutorial I followed suggest adding the price to each item in the HTML file via a custom attribute, for example data-price="100". This is very convenient and it works, but I also heard hackers could basically tamper with any of the values in an HTML form, so how to prevent them from changing the price to 1 instead of 100? Would it be safer to define the values in the Javascript document instead? Or somewhere else? What is the best practice? Thank you so much!

Generally, calculating the price of a product on the client-side is a practice that should be avoided. The best way to avoid an attack is to not calculate anything related to money on the client-side, but rather get the information from the server. Maybe you could implement a process to call the server for the price at a given point in the transaction process, initially displaying a calculated price (from your javascript). Edit: answer only.

Never trust the client. If they want to order 27 self-sealing stem bolts which cost 5 quatloos each then your JS might tell *them* that it will cost 135 quatloos but you should never trust their browser for that total. The browser should tell your server that they are ordering 27 self-sealing stem bolts. It's up to the server to determine the final amount to charge. When they make payment you should then compare the sum paid with the server-calculated cost.

PDF documents have hyperlinks to the contents on the same document (analogous to "#section" hrefs for an HTML document). Where's the back button to go back to the page I was on (where I clicked the hyperlink). Let's say I'm on the index of a PDF tutorial, page 4, and I click on Chapter 2's hyperlink in the index that takes me to page 38. Now, if I want to go back to page 4 again, which button or shortcut should I use? Within all browsers, excpet Google Chrome, you can press Alt and the left arrow to achieve this. Is there a similar shortcut within Google Chrome?

I have a NavBar in my web-app using Ruby on Rails and Twitter Bootstrap. The NAVBAR looks well in the browser as:  But, the Navbar breaks when I look up the web-app in the browser on my Galaxy Note.  *Snippet from app/views/layouts/application.html.erb* ``` <div class="masthead"> <h3 class="active"><a href="/">WebsiteName</a></h3> <div class="navbar"> <div class="navbar-inner"> <div class="container"> <ul class="nav"> <li class="active"><a href="/">Home</a></li> <li><a href="/about">About</a></li> <li><a href="/contact">Contact Us</a></li> <% if current_user %> <li class="dropdown"> <a class="dropdown-toggle" data-toggle="dropdown" href="#"> <strong><%= current_user.name %></strong> <b class="caret"></b> </a> <ul class="dropdown-menu"> <li><a href="/signout">Sign out</a></li> </ul> <% end %> </ul> </div> </div> </div> </div> ``` **The CSS for the NAVBAR** is borrowed primarily from: Justified Nav Example - <http://getbootstrap.com/2.3.2/examples/justified-nav.html> ``` /* Customize the navbar links to be fill the entire space of the .navbar */ .navbar .navbar-inner { padding: 0; } .navbar .nav { margin: 0; display: table; width: 100%; } .navbar .nav li { display: table-cell; width: 1%; float: none; } .navbar .nav li a { font-weight: bold; text-align: center; border-left: 1px solid rgba(255,255,255,.75); border-right: 1px solid rgba(0,0,0,.1); } .navbar .nav li:first-child a { border-left: 0; border-radius: 3px 0 0 3px; } .navbar .nav li:last-child a { border-right: 0; border-radius: 0 3px 3px 0; } ``` How can I fix this? I am learning Responsive CSS these days, and have no idea how to fix it. **UPDATE:** Please note that the above problem has been fixed. But I found something wrong when this got fixed though. If I decrease the size of window too much, the navbar gets broken. The User part goes outside the navbar. **The issue is also reflected in the Bootstrap example too**. I'm attaching the screenshots which showcase the issue. To see it yourself, simply decrease the window size in the [Bootstrap navbar example](http://getbootstrap.com/2.3.2/examples/justified-nav.html).  

2013/08/18

**The problem is that the "Contact Us" link is wrapping.** Notice that, in the [Bootstrap example](http://getbootstrap.com/2.3.2/examples/justified-nav.html), the navbar does not have links with multiple words. Add `white-space: nowrap;` to the `.navbar .nav li a` class. Here is a functioning [demo](http://jsfiddle.net/bsJgR/2/). All you have to do is resize the width of the frame to test. The demo contains 2 navbars: * The first navbar with the issue fixed. * The second reproduces the faulty behavior to isolate the cause at the "Contact us" link, by setting its `style` attribute to `"white-space: normal;"` thus overriding the fix. **Also note** that you have a `</li>` missing before `<% end %>`.

define the heihgt of `.navbar .nav` 40px and add `overflow: hidden;`

The NAVBAR looks well in the browser as:  But, the Navbar breaks when I look up the web-app in the browser on my Galaxy Note.  *Snippet from app/views/layouts/application.html.erb* ``` <div class="masthead"> <h3 class="active"><a href="/">WebsiteName</a></h3> <div class="navbar"> <div class="navbar-inner"> <div class="container"> <ul class="nav"> <li class="active"><a href="/">Home</a></li> <li><a href="/about">About</a></li> <li><a href="/contact">Contact Us</a></li> <% if current_user %> <li class="dropdown"> <a class="dropdown-toggle" data-toggle="dropdown" href="#"> <strong><%= current_user.name %></strong> <b class="caret"></b> </a> <ul class="dropdown-menu"> <li><a href="/signout">Sign out</a></li> </ul> <% end %> </ul> </div> </div> </div> </div> ``` **The CSS for the NAVBAR** is borrowed primarily from: Justified Nav Example - <http://getbootstrap.com/2.3.2/examples/justified-nav.html> ``` /* Customize the navbar links to be fill the entire space of the .navbar */ .navbar .navbar-inner { padding: 0; } .navbar .nav { margin: 0; display: table; width: 100%; } .navbar .nav li { display: table-cell; width: 1%; float: none; } .navbar .nav li a { font-weight: bold; text-align: center; border-left: 1px solid rgba(255,255,255,.75); border-right: 1px solid rgba(0,0,0,.1); } .navbar .nav li:first-child a { border-left: 0; border-radius: 3px 0 0 3px; } .navbar .nav li:last-child a { border-right: 0; border-radius: 0 3px 3px 0; } ``` How can I fix this? I am learning Responsive CSS these days, and have no idea how to fix it. **UPDATE:** Please note that the above problem has been fixed. But I found something wrong when this got fixed though. If I decrease the size of window too much, the navbar gets broken. The User part goes outside the navbar. **The issue is also reflected in the Bootstrap example too**. I'm attaching the screenshots which showcase the issue. To see it yourself, simply decrease the window size in the [Bootstrap navbar example](http://getbootstrap.com/2.3.2/examples/justified-nav.html).

**The problem is that the "Contact Us" link is wrapping.** Notice that, in the [Bootstrap example](http://getbootstrap.com/2.3.2/examples/justified-nav.html), the navbar does not have links with multiple words. Add `white-space: nowrap;` to the `.navbar .nav li a` class. Here is a functioning [demo](http://jsfiddle.net/bsJgR/2/). All you have to do is resize the width of the frame to test. The demo contains 2 navbars: * The first navbar with the issue fixed. * The second reproduces the faulty behavior to isolate the cause at the "Contact us" link, by setting its `style` attribute to `"white-space: normal;"` thus overriding the fix. **Also note** that you have a `</li>` missing before `<% end %>`.

Your bootstrap file loading should look like the following to make the responsive work: ``` <link rel="stylesheet" type="text/css" href="~/Content/bootstrap.css" /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" type="text/css" href="~/Content/bootstrap-responsive.css" /> ```

I want to use [js beautify](https://github.com/beautify-web/js-beautify) on some source but there isn't a way to detect what type of source it is. Is there any way, crude or not, to detect if the source is css, html, javascript or none? Looking at their [site](http://jsbeautifier.org/) they have this that looks like it'll figure out if it's html: ``` function looks_like_html(source) { // <foo> - looks like html // <!--\nalert('foo!');\n--> - doesn't look like html var trimmed = source.replace(/^[ \t\n\r]+/, ''); var comment_mark = '<' + '!-' + '-'; return (trimmed && (trimmed.substring(0, 1) === '<' && trimmed.substring(0, 4) !== comment_mark)); } ``` just need to see if it's css, javascript or neither. This is running in node.js So this code would need to tell me it's JavaScript: ``` var foo = { bar : 'baz' }; ``` where as this code needs to tell me it's CSS: ``` .foo { background : red; } ``` So a function to test this would return the type: ``` function getSourceType(source) { if (isJs) { return 'js'; } if (isHtml) { return 'html'; } if (isCss) { return 'css'; } } ``` There will be cases where other languages are used like Java where I need to ignore but for css/html/js I can use the beautifier on.

Short answer: Almost impossible. ================================ *- Thanks to Katana's input* **The reason**: A valid HTML can contain JS and CSS (and it usually does). JS can contain both css and html (i.e.: var myContent = '< div >< style >CSS-Rules< script >JS Commands';). And even CSS can contain both in comments. So writing a parser for this close to impossible. You just cannot separate them easily. The languages have rules upon how to write them, what you want to do is reverse architect something and check whether those rules apply. That's probably not worth the effort. --- *Approach 1* If the requirement is worth the effort, you could try to run different parsers on the source and see if they throw errors. I.e. Java is likely to not be a valid HTML/JS/CSS but a valid Java-Code (if written properly). --- *Approach 2* *- Thanks to Bram's input* However if you know the source very well and have the assumption that these things don't occur in your code, you could try the following with Regular Expressions. Example ------- ``` <code><div>This div is HTML var i=32;</div></code> <code>#thisiscss { margin: 0; padding: 0; }</code> <code>.thisismorecss { border: 1px solid; background-color: #0044FF;}</code> <code>function jsfunc(){ { var i = 1; i+=1;<br>}</code> ``` ### Parsing ``` $("code").each(function() { code = $(this).text(); if (code.match(/<(br|basefont|hr|input|source|frame|param|area|meta|!--|col|link|option|base|img|wbr|!DOCTYPE).*?>|<(a|abbr|acronym|address|applet|article|aside|audio|b|bdi|bdo|big|blockquote|body|button|canvas|caption|center|cite|code|colgroup|command|datalist|dd|del|details|dfn|dialog|dir|div|dl|dt|em|embed|fieldset|figcaption|figure|font|footer|form|frameset|head|header|hgroup|h1|h2|h3|h4|h5|h6|html|i|iframe|ins|kbd|keygen|label|legend|li|map|mark|menu|meter|nav|noframes|noscript|object|ol|optgroup|output|p|pre|progress|q|rp|rt|ruby|s|samp|script|section|select|small|span|strike|strong|style|sub|summary|sup|table|tbody|td|textarea|tfoot|th|thead|time|title|tr|track|tt|u|ul|var|video).*?<\/\2/)) { $(this).after("<span>This is HTML</span>"); } else if (code.match(/(([ trn]*)([a-zA-Z-]*)([.#]{1,1})([a-zA-Z-]*)([ trn]*)+)([{]{1,1})((([ trn]*)([a-zA-Z-]*)([:]{1,1})((([ trn]*)([a-zA-Z-0-9#]*))+)[;]{1})*)([ trn]*)([}]{1,1})([ trn]*)/)) { $(this).after("<span>This is CSS</span>"); } else { $(this).after("<span>This is JS</span>"); } }); ``` What does it do: Parse the text. ### HTML If it contains characters like '<' followed by br (or any of the other tags above) and then '>' then it's html. (Include a check as well since you could compare numbers in js as well). ### CSS If it is made out of the pattern name(optional) followed by . or # followed by id or class followed by { you should get it from here... In the pattern above I also included possible spaces and tabs. ### JS Else it is JS. You could also do Regex like: If it contains '= {' or 'function...' or ' then JS. Also check further for Regular Expressions to check more clearly and/or provide white- and blacklists (like 'var' but no < or > around it, 'function(asdsd,asdsad){assads}' ..) Bram's Start with what I continued was: ``` $("code").each(function() { code = $(this).text(); if (code.match(/^<[^>]+>/)) { $(this).after("<span>This is HTML</span>"); } else if (code.match(/^(#|\.)?[^{]+{/)) { $(this).after("<span>This is CSS</span>"); } }); ``` For more Information: ===================== <http://regexone.com> is a good reference. Also check <http://www.sitepoint.com/jquery-basic-regex-selector-examples/> for inspiration.

It depends if you are allowed to mix languages, as mentioned in the comments (i.e. having embedded JS and CSS in your HTML), or if those are separate files that you need to detect for some reason. A rigorous approach would be to build a tree from the file, where each node would be a statement (in Perl, you can use [HTML::TreeBuilder](http://search.cpan.org/~cjm/HTML-Tree-5.03/lib/HTML/TreeBuilder.pm)). Then you could parse it and compare with the original source. Then proceed by applying eliminating regexes to weed out chunks of code and split languages. Another way would be to search for language-specific patterns (I was thinking that CSS only uses " \*= " in some situations, therefore if you have " = " by itself, must be JavaScript, embedded or not). For HTML you for sure can detect the tags with some regex like ``` if($source =~ m/(<.+>)/){} ``` Basically then you would need to take into account some fancy cases like if the JavaScript is used to display some HTML code ``` var code = "<body>"; ``` Then again it really depends on the situation you are facing, and how the codes mix.

In my app I have a UIWebView-based view controller showing info and credits about the app itself. As part of the info, the app version is displayed, as retrieved from the infoDictionary of the mainBundle. So this string is not in the original HTML; it is set programmatically, by replacing a placeholder. Therefore the sequence is: 1) I load the HTML into a NSString 2) I replace the placeholder with the actual version 3) I show the resulting string in UIWebView by invoking method `loadHTMLString:baseURL:` The HTML also has hyperlinks to some web pages in the internet. Everything is fine, but for this problem: If I touch a hyperlink, and therefore navigate to the corresponding web page, I will not be able to go back to my original info page (canGoBack returns NO, goBack does nothing). Any suggestion? Thanks in advance.

In the end, I have found a satisfactory solution, that I would like to share. 1) I changed the HTML code of my info page, by inserting the following code where I want to show the app version: ``` <p>App version: <script type="text/javascript"> var args = document.location.search.substring(1).split("&"); for (var i in args) { var nameValue = args[i].split("="); if (nameValue[0] == "version") var version = nameValue[1]; } if (version) document.write(version); </script> </p> ``` This piece of code will parse the query part of the URL, looking for a "version=<version>" argument, and use its value to show the app version. 2) When preparing the URL to be used by the UIWebView, I retrieve the app version from the main bundle: ``` NSString* version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]; ``` Then I append it at the end of my URL string: ``` NSString* urlString = [NSString stringWithFormat:@"<my_info_page>.html?version=%@", version]; ``` 3) Finally, I use the UIWebView to show the page: ``` NSURL* url = [[NSURL alloc] initWithString:urlString]; NSURLRequest* request [[NSURLRequest alloc] initWithUrl:url]; [mWebView loadRequest:urlRequest]; [urlRequest release]; [url release]; ``` where mWebView is an IBOutlet, of type UIWebView, properly connected to the web view in the XIB file. It works correctly on my iPhone 4, including the back/forward functions of the web view when following hyperlinks, while keeping the user inside the app.

I would break out of the app and load Safari in this case: ``` - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType { [[UIApplication sharedApplication] openURL:request.URL]; return NO; } ``` The only downside is that the user comes out of your app. You could put an alertview in that method to warn them first... Alternatively, you'll have to code your own back button.

Cross-posting this question: <https://github.com/PrefectHQ/prefect/discussions/6868> I have a minimal project using Prefect v1.3.1, which you can find here: <https://github.com/b-long/aid> . I'm having a little difficulty getting the deployment right, after migrating from native code to dockerized code. I am using the latest version of Prefect v1 and need to solve this before I'm able to migrate to Prefect 2.x I'm using Poetry, but I'm pretty sure there's a pattern here that would apply to Hatch, Pipenv, Flit or other tooling. The problem is observed in registration which logs this toward the end: ``` ModuleNotFoundError: No module named 'aid' The command '/bin/sh -c python /opt/prefect/healthcheck.py '["/opt/prefect/flows/basic-pandas-flow.prefect"]' '(3, 10)'' returned a non-zero code: 1 Traceback (most recent call last): ... ValueError: Your docker image failed to build! Your flow might have failed one of its deployment health checks - please ensure that all necessary files and dependencies have been included. ``` If you're a Prefect Guru, I'm guessing you'll be able to solve this issue by reading the log file (see discussion linked above) and looking at my Dockerfile: <https://github.com/b-long/aid/blob/main/Dockerfile.prefect>

It looks like your package `aid` is relative to `/` root file system ``` COPY README.md aid/ /aid/ ``` I believe it will work if you make it relative to `/aid` dir (your working dir is `/aid` and so init file need to be in `/aid/aid/__init__.py`) ``` COPY README.md /aid/ COPY aid/ /aid/aid ```

I answered directly on the GitHub issue. Let's keep the discussion there to make it easier to follow everything in one place. Btw, great writeup on the GitHub issue, very helpful!

In Facebook how can I post a message onto a user's wall saying "I scored 8/10 on objects game" then a URL? I really don't want to have to use the full API, as I don't want to handle user login details. I don't mind if Facebook needs to authenticate and then post the message. Is it possible using the new Graph API and JavaScript?

**Note 4/16/2011:** stream.publish seems to have been deprecated, There's a new way to do this: <http://developers.facebook.com/docs/reference/dialogs/feed/> You can use something like this to publish to a wall, the user will need to confirm before it get sent. Don't forget that you'll need to use FB.init and include the JS SDK link. ``` function fb_publish() { FB.ui( { method: 'stream.publish', message: 'Message here.', attachment: { name: 'Name here', caption: 'Caption here.', description: ( 'description here' ), href: 'url here' }, action_links: [ { text: 'Code', href: 'action url here' } ], user_prompt_message: 'Personal message here' }, function(response) { if (response && response.post_id) { alert('Post was published.'); } else { alert('Post was not published.'); } } ); } ```

Considering that you have a proxy to make cross domain calls, you can simply do this... In this example, YourProxyMethod takes a jQuery.ajax like hash, makes a server side post & returns the response in success/error callbacks. Any regular proxy should do. The trick is to include app\_id and access\_token in the URL irself. Also, your FB app should have sufficient permissions to make this call. ``` YourProxyMethod({ url : "https://graph.facebook.com/ID/feed?app_id=APP_ID&access_token=ACCESS_TOKEN", method : "post", params : { message : "message", name : "name", caption : "caption", description : "desc" }, success : function(response) { console.log(response); }, error : function(response) { console.log("Error!"); console.log(response); } }); ```

[Post on wall](http://developers.facebook.com/docs/reference/dialogs/feed) will show a dialog box to share the message on wall or not.

I want to do Facebook Login on a mobile web page. This can be done with a [Facebook Login Button](https://developers.facebook.com/docs/plugins/login-button). It works great.

You can extract the RSA public key from RSA keypair using `d2i_RSAPublicKey` and `i2d_RSAPublicKey` [(link)](http://www.openssl.org/docs/crypto/d2i_RSAPublicKey.html). Use `i2d_RSAPublicKey` to encode your keypair to PKCS#1 RSAPublicKey stucture, store it in a bytestring, then use `d2i_RSAPublicKey` to decode it back to RSA key struct.

Reviewing your code, it appears that you successfully separated the `public` and `private` keys into the strings pub\_key and pri\_key, but then used `printf` to output them which pasted them back together. To just print the `public` key change the printf statement to: ``` printf("\n%s\n", pub_key); ```

I've found a solution to my question among other Stack-Overflow posts and namely [Reading Public/Private Key from Memory with OpenSSL](https://stackoverflow.com/questions/11886262/reading-public-private-key-from-memory-with-openssl) The answer i was looking for is answered by @SquareRootOfTwentyThree is his last line of code, After extracting the Public key into a BIO variable called pub: ``` PEM_write_bio_RSAPublicKey(pub, keypair); ``` i can send the variable pub across the network, and after it reaches the other side create a RSA variable and put pub inside it: SOLUTION: ``` RSA *keypair2 = NULL; PEM_read_bio_RSAPublicKey( pub, &keypair2, NULL, NULL); ``` After i've done this i can successfully encrypt the message as usual, using keypair2: ENCRYPTION: ``` encrypt = (char*)malloc(RSA_size(keypair)); int encrypt_len; err = (char*)malloc(130); if((encrypt_len = RSA_public_encrypt(strlen(msg)+1, (unsigned char*)msg, (unsigned char*)encrypt, keypair2 ,RSA_PKCS1_OAEP_PADDING)) == -1) { ERR_load_crypto_strings(); ERR_error_string(ERR_get_error(), err); fprintf(stderr, "Error encrypting message: %s\n", err); } ``` I can then send this encrypt variable back to the first machine, and decrypt it as usual, using my original `keypair`, without having to send it over the network. DECRYPTION: ``` decrypt = (char*)malloc(encrypt_len); if(RSA_private_decrypt(encrypt_len, (unsigned char*)encrypt, (unsigned char*)decrypt, keypair, RSA_PKCS1_OAEP_PADDING) == -1) { ERR_load_crypto_strings(); ERR_error_string(ERR_get_error(), err); fprintf(stderr, "Error decrypting message: %s\n", err); } ``` Thank you everyone for contributing to this post!!!

You seem to have made the question a moving target :) You should probably avoid that on Stack Overflow (I think its OK to do in those user thread forums). On Stack Overflow, you should ask a separate question.

Reviewing your code, it appears that you successfully separated the `public` and `private` keys into the strings pub\_key and pri\_key, but then used `printf` to output them which pasted them back together. To just print the `public` key change the printf statement to: ``` printf("\n%s\n", pub_key); ```

I want to download the bytes of an attachment to an email that is itself an email using Microsoft Graph. My only option at the moment appears to be to use the Get `ItemAttachment` method on the API that looks like this: ``` https://graph.microsoft.com/v1.0/users/myAccount/messages/{messageId}/attac hments/{attachmentId}?$expand=microsoft.graph.itemattachment/item ``` and the returned JSON has an `item` node with this value: ```json { "@odata.type": "#microsoft.graph.message", "id": "", "createdDateTime": "2018-01-18T01:51:02Z", "lastModifiedDateTime": "2018-01-18T01:50:36Z", "receivedDateTime": "2018-01-18T00:21:35Z", "sentDateTime": "2018-01-18T00:21:48Z", "hasAttachments": true, "internetMessageId": "<2097905212.0.1516234908909.JavaMail.root@dszsarapps01r>", "subject": "blah", "importance": "normal", "conversationId": "AAQkADQ3YjdiNWUxLTBmYWQtNDMwYy04YzDFjNgAQAFM3Iqwf0gRHqfUyw2AniAQ=", "isReadReceiptRequested": false, "isRead": true, "isDraft": false, "webLink": "https://outlook.office365.com/owa/?ItemID=AAMkADQ3YjdiNWUxLTOWQ4NDFjNgAAAA%3D%3D&exvsurl=1&viewmodel=ReadMessageItem", "body": { "contentType": "text", "content": "some content" }, "sender": { "emailAddress": { "name": "me@somewhere", "address": "me@somewhere" } }, "from": { "emailAddress": { "name": "boo@there", "address": "boo@there" } }, "toRecipients": [ { "emailAddress": { "name": "him@where", "address": "him@where" } } ] } ``` Note that the presence of attachments is indicated by the `hasAttachments` field but the attachments are not visible in the JSON. I suspect that nested attachments/emails (possibly to many levels) are not supported by Graph API but even if it were it would be risky and time-consuming trying to reconstruct the original bytes of the `.eml` attachment from JSON. I would rather treat the `ItemAttachment` as a `FileAttachment` and download its bytes. Does anyone know how to do this?

I must admit this took me a while to figure out but here it is. Get your email list you should include: - HasAttachments Attachments and also configure it .Expand("attachments") iterate around email messages if email.hasattachment iterate around the attachments{ Attachment content = await MSGraphServiceClient.Me.Messages[email.Id].Attachments[fileAttachment.Id].Request().GetAsync(); // this is the important bit which took me awhile to work out byte[] file = ((FileAttachment)content).ContentBytes; } I hope that helps.

And you could easily get the **contentBytes**. ``` https://graph.microsoft.com/v1.0/me/messages/{messageid}/attachments/{attachmentId}?$expand=microsoft.graph.itemattachment/item ``` I test it with [graph-explorer](https://developer.microsoft.com/en-us/graph/graph-explorer) ``` { "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('userId')/messages('messiageid')/attachments/$entity", "@odata.type": "#microsoft.graph.fileAttachment", "id": "AAMkAGY3ZjQxxxxxxxxxxxxxxxxxxxxx6A=", "lastModifiedDateTime": "2018-02-08T09:58:12Z", "name": "xxx.PNG", "contentType": "image/png", "size": 8419, "isInline": false, "contentId": null, "contentLocation": null, "contentBytes": "iVBORw0KGgoxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" } ``` [](https://i.stack.imgur.com/iJaQ3.png)
