Use the delegate method to add a link to a tr tag

$("table").delegate("tr","click",function(e){checkbox=$(this).children().first().children()[0];alter=$(this).children().eq(8).children().children()[0];delet=$(this).children().last().children().children()[0];if(e.target!=checkbox&&e.target!=alter&&e.target!=delet){rollcall_id=$(this).children().first().children().val()open("/Student/student?sid="+rollcall_id,"mframe");}});
