This week I’m going to give you a few tricks of the trade to use involving three things: Two dimensional arrays, using window.onload with an anonymous function and using the DOM to build a new SELECT form element. Sound obscure? I've used … er, I mean a friend of mine has used these techniques for loading advertising banners , and using a script to randomly select one of the array items in the first column, which is the banner, then grabs the associated link from the second column. Anything along those lines it would be great for.
