Is there a workaround for IE 6/7 “Unspecified Error” bug when accessing offsetParent

Question

I\'m using jQuery UI\'s draggable and droppable libraries in a simple ASP.NET proof of concept application. This page uses the ASP.NET AJAX UpdatePanel to do partial page up

My version is:

1. Add function:

   function getOffsetSum(elem) {
       var top = 0, left = 0
       while (elem) {
           top = top + parseInt(elem.offsetTop)
           left = left + parseInt(elem.offsetLeft)
           try {
               elem = elem.offsetParent
           }
           catch (e) {
               return { top: top, left: left }
           }
       }
       return { top: top, left: left }
   };
   

2. replace

   var box  = this[0].getBoundingClientRect()
   

   with

   var box = getOffsetSum(this[0])
