yes Adam that's an option if you don't want to type jQuery. each time you
uses something from the jQ Library.
Hope everyone understands whats going on, here is a little explanation:
Adam tests if jQuery is a valid object and ready to use:
If the is true he calls a self calling function and pases the jQuery Object.
The function parameter name is the $.
Within the function you have you're typical jQuery $ shortcut.
Thanks for for the snippet Adam.
It's not mine, it comes from tons of jquery extensions, and jquery
itself. It might even be a recommended best practice, listed
somewhere on their site.
