JQuery and setting checkbox to checked except disabled ones....

Got a master checkbox that you want to control the toggling of a bunch of other checkboxes in a container (but only non-disabled ones)? Want to use JQuery to make it SUPER EASY?

$('#chkMasterCheckbox').click(function(event) {
    $('#divContainer input[type=checkbox]:enabled').attr('checked', $(this).attr('checked'));
});

Oh yeah baby.
