Remove '/' at the end of string?

I'm using this function to remove http://, https:// and www. from my URLs.

function cleanUrl2(url) { 
    return url.replace(/^(http(s)?:\/\/)?(www\.)?/gi,"");
}

My problem is that I sometimes get:

google.com

and sometimes:

google.com/something/

The '/' at the end causes a lot of problems with my database. I need my function to also remove '/' if it's the last character.

How can I do this?

The URL google.com/something/ is not equivalent with google.com/something the webserver (or code behind it) decides which data is being served when requesting these URLs.

And also www.google.com is not the same as google.com, maybe they even point to different IP addresses on different machines.

So before you make any replacements think about this.

url = url.replace(/\/$/, "");

But are you sure you want to be doing this ? Depending on the web server, the URL won't necessarily work if you remove the trailing slash. You'd be better off fixing the problem with your database code that's causing having a trailing slash to be an issue really.

Try

"google.com/something/".replace(/\/$/,"")

function cleanUrl2() {
    return url.replace(/^(http(s)?:\/\/)?(www\.)?|\/$/gi,"");
}

should do the trick (on ff does)
