Teach me how to do jQuery. How do I set this class to the target value _blank

I'm getting the message was expecting target to be '_blank' not ' '.

js/app.js 
$(".external").attr("_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>

Hey KORAXE IUHMAGEON,

You forgot to specify the target attr. First you specify what attribute to target, then you assign it's value.

Try this instead $('.external').attr('target', '_blank');

Per Karlsson is spot on. Also remember to call it from within a document ready function:

(function($){

  $(document).ready(function(){

    $('.external').attr('target', '_blank');

  });

})(jQuery);

This will ensure that the DOM structure has been loaded before trying to modify your element.
