Is there a particular reason you couldn't use classes to do this?
Instead of the markup you provided, something like:
<input type="checkbox" value="EventAcceleratedOptionVesting"
id="chkEventAcceleratedOptionVesting" class="chkEvent" />
<input type="checkbox" value="AccountingChanges"
id="chkEventAccountingChanges" class="chkEvent" />
Then:
// Use the :checkbox instead of the old method you're using
$(':checkbox.chkEvent').each(funciton(){
var el = $(this);
el.attr('checked', el.is(':checked') ? '' : 'checked');
})
Would do what you're asking.
If you insist on doing it with the IDs, you can always just substr:
if ($(this).attr('id').substr(0, 8) == 'chkEvent') ...
But this method is far less efficient, and you'll be double-looping
through the tree section (once for jQuery to build an indiscriminate
collection of the nodes, then once again by your code to discriminate
the nodes and apply the check/uncheck effect)
