Only get the numbers out of an URL

Question

I only want to have the numbers of my URL as return. At the moment I use:

alert(document.URL);

to get the whole URL. But is there any other easy solution to get only the ID-Numbers from my URL as result? I also use jQuery and PHP in this project.

maybe ur looking for query string [query string][1] [1]: http://stackoverflow.com/questions/901115/how-can-i-get-query-string-values — Vicky Gonsalves, Oct 24 '13 at 16:02

var numbers = document.URL.match(/\d+/g) will return all numbers in a URL (eg for this thread) document.URL.match(/\d+/g) => ["19570840"]

But can you tell me what this (/\d#/g) stands for? – Yannic Hansen Oct 25 '13 at 07:08

@YannicHansen `\d` will match a number, `#` is a symbol, and the `/g` is the global flag. So together that regex will match all the first numbers followed by a pound symbol. eg `"test1321#a and #1 and 313#a".match(/\d#/g);` => `["1#", "3#"]` – megawac Oct 25 '13 at 14:16
Thanks for explaining this to me! – Yannic Hansen Oct 25 '13 at 14:22

alert(document.URL.match(/\d+/g));

Simple. I would put it in a fiddle, but uhh, jsFiddle doesn't have any numbers in their url, so.
