Using JQuery in Drupal 7
Looks like adding custom JQuery scripts in Drupal 7 just got harder.
The $ is no longer specific to JQuery as it allows flexibility to other javascript libraries.
Therefore, to get a JQuery script to be recognized in Drupal 7, you need to wrap the code in an anonymous function... like this...
(function($) {
$().ready(function() {
//...
});
})(jQuery);
