There was an error with your code: ReferenceError: Can't find variable: target

I'm having difficulty passing this code challenge, am I using attr() incorrectly or do I need to write additional code for this to function?

Thanks!

js/app.js 
$("#external a").attr(target, "_blank");
index.html 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
  <title>Links Page</title>
</head>
<body>
  <h1>Links</h1>
  <ul>
    <li><a href="http://google.com" class="external">Google</a></li>
    <li><a href="http://yahoo.com" class="external">Yahoo</a></li>
  </ul>
  <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
  <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

Hi,

there's a couple of errors in your js script:

$("#external a").attr(target, "_blank");

First with # you select the id not the class and you need to reverse with the a at the beginning, second you must surround target with quotes.

See my code:

$("a.external").attr("target", "_blank");
