You have to select all the links that actually have that class already. You could do that like this:

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

Sorry, I thought it was other code challenge

Remember, you select all the anchor tags or "links" by using this selector:

$("a")

And if you need to select all the anchor tags who have the ".external" class you would do it like this:

$("a.external")

Hi,

You haven't added any code in your js snipet but what the challenge is asking you to do is a couple of things.

1 select all achor elements using jquery

$("a")

2 add the class of "external" to all of them.

$("a").addClass("external")

3 lastly add the attribute of target with a value of _blank

$("a").addClass("external").attr("target", "_blank")

This is what the finished code looks like.

I hope this helps.

Happy coding.
