Q:

Validating Input Fields with JavaScript or jQuery

I need to check to make sure that four  fields have some kind of value in them. 
I have tried these ideas:
Check whether a select box is empty
How to tell if a DDL has options to select
My code is currently this:
    function goToConfirmStep() {
    var isAllowed = false;
    var type = $(".#tShowingType option:selected").val(); //DDL
    var startDate = $("#startDate").text(); //date picker
    var startTime = $("#startTime option:selected").val(); //DDL
    var endTime = $("showingLength option:selected").val(); //DDL
    if (type.val() ) { //&&   //(type ! = null || type ! = "")
    //(startDate.text() == "" || startDate.text() == null)) {//&&
    //($('#startTime').has('option').length > 0) &&
    //($('#endTime').has('option').length > 0)) {
    alert("here");

I left the comments in so you can tell what I have tried. 
If they have values selected (which the 'type' and 'startTime' will have one selected on load), I want to move to the next page.   I have an alert on the else to prevent them from moving forward if the fields aren't filled out.

I eventually had to attack it a different way.   This is what I did:
