jQuery - Internet Explorer 8 - Error

Hey all,

im stuck on a problem using jQuery on IE8.

I get an Error on Line 74 Character 424 (jquery.1.4.2.min) "The Object does not support this method".

(FF is working as expected without error!)

My JavaScript is:

  1. //This is working
    $('#content').append('<h1>Content added by jQuery - JavaScript!</h1>'); 
    //This not
    //When page loads...
     $(".tab_content").hide(); //Hide all content
     $("ul.tabs li:first").addClass("active").show(); //Activate first tab
     $(".tab_content:first").show(); //Show first tab content
     //On Click Event
     $("ul.tabs li").click(function() {







  2.   $("ul.tabs li").removeClass("active"); //Remove any "active" class
      $(this).addClass("active"); //Add "active" class to selected tab
      $(".tab_content").hide(); //Hide all tab content

  3.   var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content
      $(activeTab).fadeIn(); //Fade in the active ID content
      return false;
     });


Thanks for your support!
