TypeError: $ is not a function when calling jQuery function

Question

I have a simple jQuery script in a WordPress plugin that is using a jQuery wrapper like this:

$(document).ready(function(){

    // jQuery code is in here

}         


        

Answer 1

Use

jQuery(document).

instead of

$(document).

or

Within the function, $ points to jQuery as you would expect

(function ($) {
   $(document).
}(jQuery));
