title: How to do 'back' in a div tag using jQuery
body: <p>I have a div element in my html and I have a link in it. On clicking this link, I load some other content to the div area using AJAX. The new content has a 'back' link and when user clicks this link I want to show the previous contents in the div area.</p>
  
  <p>I could achieve this by storing the contents to a dummy div before loading the new contents and putting it back when user clicks the back link. Is there a more straight-forward way to achieve this in jQuery?</p>
