This code is working perfect to mouseover:

1.  $(document).ready(function() {
                               
        $("#main ul li").hover(function(){
      
       var fade = $('img.g-img', this);
       fade.fadeTo('slow', 0.5);
       
   
      $("#main ul li").removeClass("active");
       $(this).toggleClass("active");
   });
   
       
   });
   
   
   
   
   
   
   
   
   
   
   
   
   
   

But what about mouseout? I want to remove effect like "removeEventListener" in as3.0,
How can I do this?
Thanks in advance
