jquery dynamically added checkbox not working with change() function

Question

I dynamically load in a few li's that have a label and a checkbox in them to another visible ul. I set the checkboxes to be checked="checked" and i am trying to trigger an event to happen when i change these dynamically inserted checkboxes but nothing occurs.

Here is the jquery:

$(".otherProductCheckbox:checkbox").change( function(){
    alert('test');
});

Here is the html for the dynamically added li's:

<li class="otherProduct"><input type="checkbox" class="otherProductCheckbox radioCheck" checked="checked"/><label>Product Name</label></li>

Any idea why i cant get the alert to happen when the checkbox changes its checked state?

Solution 1

You have to use liveQuery or live to bind events to dynamically added elements.

$(".otherProductCheckbox:checkbox").live('change', function(){
    alert('test');
});

EDIT To work in IE, you have to use click not change

$(".otherProductCheckbox:checkbox").live('click', function(){
        alert('test');
 });

Solution 2

Since live() is now deprecated as of jQuery 1.7, I thought I'd post the solution that worked for me on the same problem (trigger event when dynamically added checkboxes are changed).

$(document).on('click', '.otherProductCheckbox', function() {
    alert('test');
});

@Teja Kantamneni: Perfect. Thanks for the direction. Still learning the ins and outs of jquery.

You're only required to do that if the elements are being added after the event handler has been set up.

@Gareth: yah that makes sense now.

Actually, this doesn't seem to be working in IE, works in Safari and FF... Any ideas?

Thats the issue with IE, IE will trigger change event only after the element looses the focus. webbugtrack.blogspot.com/2007/11/…

For fix, use click instead of change

@Teja Kantamneni: That did the trick. Thank you again! Tricky stuff

document.getElementById('id').live('click',function() { alert('test'); }); It is not working for me.. what "otherProductCheckbox" means here ?
