Change href of external links

Hi all,

New to jQuery, and I'm trying to use it to set my external links to open a new window without using any attributes to  mark the external links.  I can do this with regular js, using a.href.match, but I can't get it to work with jQuery.  Tried various directions, but no go.

Sure I'll feel pretty stupid when this is answered, but here is my ugly, non-functioning code:

$(function(){
    if ($!("a").href.match("http://www.internal.com")) {
        $("a").click(
             function() {
                 window.open(this.href); return false;
                 console.log("external");
             };
        );
    };
});



Thanks for any help,
Adam
