jQuery change event on <select> not firing in IE

Question

I've got a page with a variable number of <select> elements (which explains why I'm using event delegation here). When the user changes the selected option, I want to hide/show different content areas on the page. Here's the code I have:

$(document).ready(function() {
  $('#container').change(function(e) {
    var changed = $(e.target);

    if (changed.is('select[name="mySelectName"]')) {
      // Test the selected option and hide/show different content areas.
    }
  });
});

This works in Firefox and Safari, but in IE the change event doesn't fire. Anyone know why? Thanks!

Answer 1

I'm trying to understand why you need to double check the name of the select after receiving an event to it.

Do you by any chance have multiple elements with the same id ?

Did you actually mean to say "#container select" instead of "#container" ?

Idea that might help:

$(document).ready(function() {
  $('#container select[name="mySelectName"]').change(function(e) {
    var s = $(e.target);
    if (s.val()=='1') //hide/show something;
  });
});

If you are using AJAX, try live() function:

 $(document).ready(function() {
       $('#container select[name="mySelectName"]').live('change', function(e) {
        var s = $(e.target);
        if (s.val()=='1') //hide/show something;
      });
    });

If I recall correctly you will need to call blur() to have jQuery invoke change() on IE machines. Try something like:

$("select[name=mySelectName]").click(function() {
    $(this).blur();
});

The change event does not bubble in IE (See here and here). You cannot use event delegation in tandem with it. In fact, it is because of this IE bug that jQuery live had to officially exclude change from the list of supported events (FYI the DOM spec states change should bubble).

You will need to bind directly to each select:

$('#container select').change(/*...*/)

If you really want event delegation you might find some success trying what this person did and bind to click in IE only, which does bubble:

$('#container').bind($.browser.msie ? 'click' : 'change', function(event) {
    /* test event.type and event.target 
     * to capture only select control changes
     */
})

But this browser detection feels really wrong. I'd really try working with the former example (binding directly to the drop downs). Unless you have hundreds of <select> boxes, event delegation wouldn't buy you much here anyway.

Add this lines to your page head, Sit back and relax! :)

$(document).ready(function(){$('select').bind('onChange',function(){$(this).blur()});});
