[Javascript] A loop for this script? Is it really possible?

[Mike Dougherty]

function attachMouseEvents( id ) {
   document.getElementById(id).onmouseover = new Function( "movr(" + id + ")" );
   document.getElementById(id).onmouseout = new Function( "mout(" + id + ")" );
   }

function movr( id ) { window.status = "mouseover: " + id }
function mout( id ) { window.status = "mouseout:" + id }

I think the proper terminology for what you're doing is creating a 'closure'  (i'm not 100% clear 
myself, but this solved this exact problem for me recently)

this is what i used to figure it out:

BTW, testing mouse events with alert() is tedious and painful, so I used window.status instead.
