Code is not working.

I added an id to the ul called "links" and used it to write this:
$("links a").append("target='_blank'");

js/app.js

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>

:point_right: You may be using the wrong function.

"Append" is used for adding new content to the document. You probably want the function that will add an attribute to an existing element (or set of elements).

Hint: It also starts with "a".

So if I write: $(".external a").attr("target", "_blank"); I'm still getting an error " Bummer! I was expecting target to be _blank not ``"

Do I have to add the "target" attribute somehow? Doesn't seem like it should be this difficult? Thanks btw!

I figured it out thanks. Overthinking it I believe: $("a.external").attr('target','_blank');
