Determine if Link is valid upon user clicking on it
<p>I offer a widget where a user can store their links that they have created.</p>

<p>So in other words They:</p>

<ol>
<li>Click Add Link</li>
<li>Modal Pops up and they enter information: Link Title, Link URL, Order</li>
<li>Saves that to the DB via AJAX and then refreshes the widget to display all of the users links they have created.</li>
</ol>

<p>What I would like do is when the user clicks on their link, determine if the link exists(Could be not on this domain so I can see a foreseeable issue w/ AJAX) if it does then proceed with normal Open new Window and send them on their merry way. </p>

<p>However if not I would like to generate a Growl Like message that says something like.</p>

<blockquote>
  <p>I'm sorry that Link Does not exist,
  please verify your link.</p>
</blockquote>

<p>I basically need the method for validating the links existence on a client side basis. Is this even possible ?</p>
