title: Jquery replacing body background-image with fadeout and fadein effect
body: <p>I just want to change background-image of body with a fadeOut and replace the second image with fadeIn.<br>
  But I get the following error:</p>
  
  <pre><code>Uncaught TypeError: Object url(file:///C:/Users/.../p1bg_cutted.png) has no method 'fadeOut'
  </code></pre>
  
  <pre class="lang-js prettyprint-override"><code> $('body').css("background-image").fadeOut('slow',function(){
      $("body").css("background-image",
      "url(Images/son_componentler/p2bg_cutted.png)").fadeIn('slow')
  
   });
  </code></pre>
  
  <p>I can change the image without fadein/fadeout but I guess in that case I am making a sytax mistake.</p>
