Launching a jQuery script

Most of the time you'll want your script to launch and/or be available as soon as the DOM is loaded and ready. For this, you can use the standard "on document ready" technique as follows:

jQuery(document).ready(function(){
// Your jQuery script go here
});

You can reduce the previous code, just a bit, by using the following code:

jQuery(function(){
// Your jQuery script go here
});

If the jQuery variable is evoked and a function immediately passed, jQuery assumes the .ready event is implied and will run the next selection and function as soon as the DOM is loaded.
