Using Multiple JavaScript Onload Functions

An interesting article. I’m particularly intrigued by the “The addLoadEvent Function” discussed about halfway down the page.

"The way this works is relatively simple: if window.onload has not already been assigned a function, the function passed to addLoadEvent is simply assigned to window.onload. If window.onload has already been set, a brand new function is created which first calls the original onload handler, then calls the new handler afterwards."
