title: Hide control depending on url
body: <p>My url is of the format <a href="http://www.xyz.com/DisplayPost.php?postid=200" rel="nofollow noreferrer">http://www.xyz.com/DisplayPost.php?postid=200</a></p>
  
  <p>I want to detect if the url has "postid=250" in it and hide a div called divOne</p>
  
  <p>How can I do it using jQuery</p>
