jQuery conflict between scripts

I am using CakePHP and am using 2 javascript scripts one of which relies on jQuery.

On one of these javascripts the $ variable is used which conflicts with jQuery and thus

I had to include the following bit of code in cakephp :

    <?php 
    $this->Js->JqueryEngine->jQueryObject = '$j';
    print $this->Html->scriptB开发者_开发百科lock('var $j = jQuery.noConflict();', array('inline' => false));
 ?>

This made the javascript + jQuery inclusion work fine. I then wanted to add another javascript which requires jQuery - which I have however I get the following error:

Uncaught TypeError: Object function $(element) {  if (arguments.length > 1) {
for (var i = 0, elements = [], length = arguments.length; i < length; i++)
  elements.push($(arguments[i]));
return elements;  }  if (Object.isString(element))
element = document.getElementById(element);  return Element.extend(element);} has no method 'extend'

I am not a massive javascript buff. But this confuses me and obviously there is a conflict - please help me get this jQuery based script work.

Thanks,

You need to use the no conflict selector that you defined in the no-conflict section, i.e. $j instead of simply $.
