Accessing iFrame with jQuery
Monday, September 21st, 2009Dynamically add an icon for external links with jQuery
Thursday, September 17th, 2009A common feature I've seen on “web 2.0” sites and wikis is the "external link" icon: 
. While I'm not crazy about the idea of sticking these little images all over the HTML, they're a great candidate for using progressive enhancement. In our case, we can use jQuery to add the images pretty easily.
Test the hostname
To identify the external links, we test for the location.hostname against the link's hostname, which will be represented by this.hostname once we have the selector in place, and make sure the two don't match. We should also test for the mere existence of this.hostname to avoid problems or false positives with "mailto" links. our tests will look like this: this.hostname && location.hostname !== this.hostname.
Use the filter function
Now let's wrap that test in a filter function. For our example, we'll test all links inside an "extlinks" element that match the above test. Here is what it looks like:
$(document).ready(function() {
$('#extlinks a').filter(function() {
return this.hostname && this.hostname !== location.hostname;
}).after(' <img src="/images/external.png" alt="external link"/>');
});
A $(document).ready() is wrapped around the script so that it will execute when the DOM has loaded. Line 4 shows the insertion of the image after each of the external links.
