title: How to reload, a part of a webpage after a given time?
body: <p>What i want to do is, to show a message based on certain condition.
  So, i will read the database after a given time continuously, and accordingly, show the message to the user. 
  But i want the message, to be updated only on a part of the page(lets say a DIV).</p>
  
  <p>Any help would be appreciated !
  Thanks ! </p>
