[jQuery] highlight navbar

[new to jquery]

I'm trying to make a navigation bar with highlighted tabs.  It works
when I specifically click the tab, but if I come to the page from an
outside link, I can't get the tab to highlight.  How could I say
something like:

$("#navbar a").each(function(){
     if(this.href *like* window.location)
        (this).addClass("selected")
}

What do I put in place of *like*?

Or if you know another good way to do it, that would be helpful.
Thanks in advance.
