Opening a link in a new tab using JQuery

I'm trying to get all the links of a given class ('external') to open in a new tab. The error message from the Challenge Question is 'I was expecting target to be _blank not ``.

$('#external a').attr('target', '_blank');
<!DOCTYPE html>
  <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
  <title>Links Page</title>
    <li><a href="http://google.com" class="external">Google</a></li>
    <li><a href="http://yahoo.com" class="external">Yahoo</a></li>
  <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>

You'll want to adjust the selector you're using. # let's you select IDs just like a CSS selector. You want to do something like this instead:

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

Which would be every link with the class external.

The selector you're using in JQuery is selecting all the link ("a") tags inside of the id "external". Looking at your html, you have a link with the class of "external" but with no links inside it.

Therefore, your JQuery should look like what Tim wrote; with a "." instead of a "#" and with the "a" tag before the class name. If the "a" tag is confusing to you, you can just not use it, though it's a good habit to include it.

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


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