The new .on() and .off() APIs unify all the ways of attaching events to a document in jQuery: bind, unbind, delegate, undelegate, live, die - which are now deprecated.
<script> $(elements).on( events [, selector] [, data] , handler ); $(elements).off( [ events ] [, selector] [, handler] ); </script>
When a selector is provided, .on() is similar to .delegate() in that it attaches a delegated event handler, filtered by the selector. When the selector is omitted or null the call is like .bind().
<script> $('a').bind('click', myHandler); $('a').on('click', myHandler); $('form').bind('submit', { val: 42 }, fn); $('form').on('submit', { val: 42 }, fn); $(window).unbind('scroll.myPlugin'); $(window).off('scroll.myPlugin'); $('.comment').delegate('a.add', 'click', addNew); $('.comment').on('click', 'a.add', addNew); $('.dialog').undelegate('a', 'click.myDlg'); $('.dialog').off('click.myDlg', 'a'); $('a').live('click', fn); $(document).on('click', 'a', fn); $('a').die('click'); $(document).off('click', 'a'); </script>
