Question

Example http://jsfiddle.net/Rg8rf/

$("#label").change(function() {
    var src = $(this).data('value');
    alert(src);
});

How do I grab a value from data-value?

Answer 1

this in that case means the select list, so you have to catch the selected value inside “this”. This will work for you:

$("#label").change(function() {
    var src = $(this).children(":selected").data('value');
    alert(src);
});​

Its very easy to test in this cases if you are not sure and don’t get the value of what you expected. Inside the change method you could just write console.debug(this) and look in the console to see whats inside, or just alert($(this).attr(“id”))
