Q:

Jquery/JS prevent right click menu in browsers

I have my div with a right click popup menu:
// Attatch right click event to folder for extra options
$('#fBox' + folderID).mousedown(function(event) {
    if (event.which == 3) {

        // Set ID
        currRClickFolder = folderID;

        // Calculate position to show popup menu
        var height = $('#folderRClickMenu').height();
        var width = $('#folderRClickMenu').width();
        leftVal = event.pageX - (width / 2) + "px";
        topVal = event.pageY - (height) + "px";
        $('#folderRClickMenu').css({ left: leftVal, top: topVal }).show();

    }
});

But the browser for this element still pops up the default menu (copy/paste/properties etc).   Any way to disable this?   I've tried return false but not luck. 

A:

You can disable the right click by appending oncontextmenu="return false;" to your body tag. 
<body oncontextmenu="return false;">

You can disable context menu on any element you want:
$('selector').contextmenu(function() {
    return false;
});

To disable context menu on the page completely (thanks to Ismail), use the following:
$(document).contextmenu(function() {
    return false;
});

A:

One jQuery line:
$('[id^="fBox"]').on("contextmenu", function(evt) {evt.preventDefault();});
