and code or offset jquery not work me:

                function getabsoluteelementposition(element) {                   if (typeof element == "string")                     element = document.getelementbyid(element)                    if (!element) return { top:0,left:0 };                                         var y = 0;                   var x = 0;                   while (element.offsetparent) {                     x += element.offsetleft;                     y += element.offsettop;                     element = element.offsetparent;                   }                   return {top:y,left:x}; 

var pos = getabsoluteelementposition(element);

when normal html if works perfectly.
