On-demand load of JavaScript libraries

With a creative approach to DOM model, you can load JavaScript libraries on demand from your web pages. What you need to do is to create a SCRIPT element, set its SRC attribute and insert it into the document. You could use a function similar to this one ...
function LoadScript(url)
  var lib = document.createElement(’script’);
  lib.src= url;

... or you could use a safer xLoadScript function from the X library.

The X library also provides a xSmartLoadScript function to stop you from loading the same library multiple times.

In a recent post on PeachPit.com, Kris Hadlock gives you a few ideas where this functionality might come handy.
