Answer 1

If I'm understanding you correctly, you want to clear all the items when they click "Check All" - you might want to change the name to "Clear All" for clarity.

If so, just add a simple ! in front of this.checked

$('#checkAll').click(function () {
$('input:checkbox').prop('checked', !this.checked); });
