JavaScript jQuery Basics (2014) Creating a Simple Lightbox Adding New Attribute Values with attr()

Posted by Travis Dalhoff

Using jQuery only, add to all links with the class "external", the target attribute with the value of "_blank"

I'm really not sure what this question is asking for. I've gone back through the videos in this section and I can't find where we used the target attribute before and I'm really confused. I've tried multiple variations of the code I have here and nothing seems to be working. Any help would be appreciated.

js/app.js 
$(".external:target").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>

You have the right structure, but the arguments are a bit mixed up.

First, there's no "target" pseudo-class, but the challenge only asks that the ordinary class "external" be selected. On the other hand, the attr function takes two arguments, the name of the attribute and the value being assigned to it. And "target" is the name of the attribute that you want to set. So with a little re-arranging, you might have this:

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

Thanks a lot! I appreciate it. I've been stuck on that for awhile!
