Oh, I see - you've got more of a scope issue than I first thought.

Solving the scope of 'i' broke the closure over MyWorld and MyDesc that you had.

I'm sure you can fetch the MyWorld element from its ID, but MyDesc is different.

In these stuations I am more inclined to do the following:

  function mouseover()
  {
    var myWorld = document.getElementById('<myWorldId>');
    myWorld.nodeValue = this.desc + ' world';
  }

  for (i in MyDesc)
  {
    var MyPointer = document.getElementById(i)
    MyPointer.desc = MyDesc[i];
    MyPointer.onmouseover = mouseover;
  }
