/* Add a listner to Group buttons */    $(‘a.preActNav‘).click(function() {         alert(this.seq)    });       <li><a href="http://www.mamicode.com/#preclose4" data-theme="a" data-icon="arrow-d" data-transition="none" seq=‘1‘ class="preActNav"  ID="preActNavA">A</a></li>    <li><a href="http://www.mamicode.com/#preclose4" data-theme="a" data-icon="arrow-d" data-transition="none" seq=‘2‘ class="preActNav"  ID="preActNavB">B</a></li>

alert($(this).attr(‘seq‘));

Although it may be better to put seq as another data element:

<li><a href="http://www.mamicode.com/#preclose4" data-theme="a" data-icon="arrow-d" data-transition="none" data-seq=‘1‘ class="preActNav"  ID="preActNavA">A</a></li>

So then you can do:

alert($(this).data(‘seq‘));
