JavaScript - Find position

This is kind of a useful script for setting the window's scroll position to that of an object's in javascript.

function Scroll2Pos(cID) 
      {
        var obj = document.getElementById(cID);
        var curtop = 0;
        if (obj.offsetParent) 
        {
          do 
          {
            curtop += obj.offsetTop;
          } 
          while (obj = obj.offsetParent);
          window.scrollTo(0, curtop);
        }
      }

It is based on this.
