I have some custom field and I am trying to show it in a popup window. I don't want to add another library. So, how can I show modal dialog like (print options, claim...) etc. This is what I have done but it is not working.I added below to ticket-view.inc.php just to test <script type="text/javascript"> $('a#konum-print').click(function(e) { e.preventDefault(); alert("Hello world Before") $('#overlay').show(); $('.dialog#konum-options').show(); alert("Hello world After") return false; });</script><a id="konum-print" href="tickets.php?id=50&a=print"><i class="icon-print"></i>Show Map</a><div id="konum-options" class="dialog" style="display: none; top: 133.429px; left: 556.5px;"><h3>Google Map</h3><a class="close" href=""><hr><div class="clear"></div></div>However clicking show map link doesn't do anything.
