Regex on url in Javascript

Question

I've NEVER been good with regular expressions despite my efforts. Can someone please help me out I'm trying to match urls in this format:

"/year/monthnum/day/postname/"

so:

"2012/05/03/whatever-the-text-here"

using:

if(window.location.pathname.match(...))
{
 //do something
}

I've tried a couple of things but I'm just terrible with regex... Can someone help me out here?

http://regexr.com?30ram

if(window.location.pathname.match(/\/?[0-9]{4}\/[0-9]{1,2}\/[0-9]{1,2}\/.+$/))

this can be enhanced also to check that day is not 0... or things like that... but i think its enough.

Awesome.. thanks very much Royi, one day I will find the time to spend a whole day getting to grips with regex but it's always been a minefield to me..

Try this:

if (/(?:(?:\d{4})[\\\/](?:\d{2})[\\\/](?:\d{2})[\\\/])([^\\\/]+)/m.test(subject)) {
    // Successful match
} else {
    // Match attempt failed
}

@stema:Right, but it could supports both the slashes, hence the effort!

hey Cylian, Thanks for your help, I've gone with the other simply because I understand whats going on better which is a little unfiar because I really dont understand regex too well but it will make it easier for me if I need to work with it
