Description: I have a page with an iframe in it. iframe contains a link which when clicked opens a tinybox plugin displaying the contents of another page, but since the space available to iframe is limited so in order to use the full client width of the browser what i have done is that on the loading of iframe i am binding the links inside the iframe using the code given below

       if(sender.contentDocument)
            windowDocument = sender.contentDocument;
       else
            windowDocumet = sender.contentWindow.document;
       
       windowDocument.domain = document.domain;
       $(windowDocument.body).on("click",'.lnkdropbox',function(e){            
           TINY.box.show({iframe:'sitetobeopened',boxid:'frameless',width:$(window).width() - 50,height:$(window).height() - 50,fixed:false,maskid:'bluemask',maskopacity:40,closejs:function(){closeJS()}});
           e.preventDefault();
       });      

The above code is run when the iframes onload event is fired.

This code runs well on IE and Google Chrome, but gives error on Mozilla.

On the contrary if i bind the iframes links using normal click event, it works fine on mozilla but then the functionality breaks on IE and google chrome
