Using wildcards in URL variables (very simple question, i know)

Hi all!

Pulling my hair out over this... How do I use wildcards in URL variables? I have this code in compositionReady (which is working):

var myurl = "http://www.mydomain.com/sub1/sub2/pagename";

var currenturl = window.location

if(myurl == currenturl) {

    sym.getSymbol("symbolname").play();

}

It simply makes the symbol "symbolname" play when the current URL matches the variable 'myurl'. However, I want the symbol to play on ALL subpages to http://www.mydomain.com/sub1/sub2/ and therefore it seems logical to put in a wildcard like:

http://www.mydomain.com/sub1/sub2/* or something similar, but I just can't seem to make it work??

Any help will be greatly appreciated!

:-)

Best,

Thomas
