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!
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 .[1]live
had to officially exclude change
from the list of supported events (FYI the DOM spec states change
should bubble)
With respect to your question, you can 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.
[1] Note: jQuery >= 1.4 now simulates a bubbling change
event in IE via live()
/on()
.
