Using JQuery in Drupal 7

Question

I\'m writing my own Drupal 7 module, and like to use JQuery in it.

$(\'#field\').toggle();

But I\'m getting this error:

TypeErr

According to Firebug, your jQuery file is being loaded:

But the $ is being overwritten by something else:

What you should do is encapsulate the use of the $ variable with a function that invokes itself using the jQuery object as it's first actual argument:

(function ($) {

 // in this function, you can use the $ which refers to the jQuery object

}(jQuery));
