Question

I am writing an application at the moment that uses jquery. It fits in to an existing application that uses prototype so obviously I cant use the dollar sign straight away.

I have been using noconflict to get around this but couldnt I just wrap my whole script inside a closure passing in jquery as in:

(function( $ ){

})( jQuery );

This seems to work but I am wondering if there are any consequences to this?

Answer 1

That should work fine, since your passing jQuery into your closure as the jQuery object itself.

The noConflict should still be specified though – otherwise the jQuery object could take control of the dollar sign. Calling noConflict passes the dollar sign back to anything that is already using it.

The documentation suggests this too:

  $.noConflict();
  jQuery(document).ready(function($) {
    // Code that uses jQuery's $ can follow here.
  });
  // Code that uses other library's $ can follow here.
