Use .text() for this:
alert($(this).text());
If you wanted the markup (.text() removes tags and such), use .html()
alert($(this).html());
In this case there’s no difference, if instead you had this:
<a href="http://www.google.com/">Google <span>(External)</span></a>
Then there would be:
$(this).text() //"Google (External)"
$(this).html() //"Google <span>(External)</span>"
