javascript - JQuery event to fire when a drop down is selected -- but the value is not changed

Question

I have a dropdown menu that I want to connect a JQuery event to that fires if someone clicks on it but then selects the same option that is already selected.

I've got everything running using the 'change' event but there are cases where it's valid for the user to click the dropdown and reselect the same option. If that occurs I need my event handler to fire.

How can I do this?

Try something like below,

Using .click

$(function () {
    var cc = 0;
    $('select').click(function () {        
        cc++;
        if (cc == 2) {
            $(this).change();
            cc = 0;
        }         
    }).change (function () {
        $('#result').append('Changed triggered ');
        cc = -1;
    });     
});

Or using .focus and .blur

$(function () {
    var ddVal = '';
    $('select').focus(function () {
        ddVal = $(this).val();
    }).blur(function () {
        if (ddVal == $(this).val()) {
            $(this).change();
        }
    }).change (function () {
        $('#result').append('Changed triggered ');
    });       
});
