Random iframe content

Author: Dynamic Drive

Description: This script randomly selects from a group of URLs and displays one of them inside an iframe. Since it's an iframe, the content can be anything and everything. Some ideas for using this script are:

Randomly rotate and display HTML banners
Display a "random joke" from a large archive without having to download everything
Serve up random content consisting of rich HTML

The script works in IE4+/NS6+, and simply displays nothing in all other browsers.

Demo: (refresh the page to see a different content below)

Directions:

Simply insert the below code where you wish the content to appear, and configure the URLs inside to your own:

Select All
