Joomla 2.5 Jquery Cannot call method of null

Question

Hi guys I am using Joomla 2.5 with Jquery and I got this strange error in my chrome console:

\"Uncaught TypeError: Cannot call method \'slideUp\' of null \"

Most probably your jquery code is conflicting with mootools. Try this using

jQuery.noConflict();

Your code will be like below-

var $j = jQuery.noConflict();
$j(document).ready(function(){

    var slider = document.getElementById("login-form");

    alert (slider);

    $j("#login-form").slideUp(100);

});
