Get clicked option in multiple dropdown

Answer 1

You can get it in the click handler for each option element:

$("#myList option").click(function() {
    var clickedOption = $(this);
});

Update

EDIT: As I manipulate the list inside a change event, I can't do it in a click event.

In that case you need to delegate the event using on. Try this:

$("#myList").on("click", "option", function() {
    var clickedOption = $(this);
});

One thing to note, however, is that option elements will not raise click events at all in IE, so neither of the above will not work in that browser.
