JS method to set the absolute position of ff and ie elements_javascript skills

The example in this article describes how to implement JS to set the absolute position of ff and ie elements. Share it with everyone for your reference, the details are as follows:

function Show_menu(liid,divid)
{
  var li=document.getElementById(liid);
  var div=document.getElementById(divid);
  div.style.left=getLeft(li)+140+'px';
  div.style.top= getTop(li)+'px';
  var tt=div.style.top;
  div.style.display='block';
  alert(tt);
}
function getTop(e){ //用递归方法取值
  var offset=e.offsetTop;
  if(e.offsetParent!=null) offset+=getTop(e.offsetParent);
  return offset;
}
function getLeft(e){
  var offset=e.offsetLeft;
  if(e.offsetParent!=null) offset+=getLeft(e.offsetParent);
  return offset;
}
