Checkbox change event not firing

Question

This is my code:

Answer 1

Try changing

$('a').click(function() {
      $('.chk').attr('checked', true);
});

To -

$('a').click(function() {
      $('.chk').attr('checked', true).trigger('change');
 });

That should force a trigger of the 'change' event.

Answer 2

try this.

<div id ="chkall"> <a href="#">check all</a> <div>

            $('#chkall a').live("change", function() {
            $('.chk').attr('checked', true);
            });

Answer 3

use: $('.chk').attr('checked', true).change();

Answer 4

When you change the attribute also use the following:

$('.chk').trigger('change');

Or in your code like other people have suggested:

$('.chk').attr('checked', true).trigger('change');
