Change arrows.

Change arrows.

Hi, I'm trying to change image for my button when class .slide is up or down. This is the code:


  1. $(document).ready(function() {
  2.       var $panel = $('.slide');
  3.       var $panelBut = $('.button');
  4. $panel.slideUp('fast');
  5. $panelBut.click(function() {
  6.              $panel.slideToggle('fast').css('background-image', 'url(../img/up.jpg)'); 
  7.     });
  8. });
