how can I get the value from that plugin

1) $(document).ready(function(){
2) $("a").click(function(){
3)    var td = event.srcElement;
4)  //var myValue = $("#cn").attr('href');
only got the value on the html, however, it seems impossible to trigger
any event on the plugin. The code of "plugin" can only be read from
inspect  mode on browser. So,this problem still needs more investment.
