Remove or hide div if undifined/null or empty
<p>I have a script which can display information based up on  url and save this information: <a href="http://moskah.nl" rel="nofollow">moskah.nl</a></p>

<p>The problem is that if you would click the button without giving url than the script will give an empty div. Just reload the page and you will see it will still be there. </p>

<p>What can I do in Jquery in order to remove or hide these emty divs on document ready?</p>
