Using Javascript regex, how to get a value between some phrase..?

Question

In my url, i'm suppose to get the token number, but the token number may be Numeric or Alpha. I need to get the token always in different scenario. How do I achieve that using Regular Expressions?

Sample URLs:

?&token=1905477219/someother/stuff

&token=1905477219

&token=xyzbacsfhsaof

&token=xyzbacsfhsaof/some/other

How can I always get the token from these kind of URLs?

I tried this:

/(token=.*)/g

I am looking for :

?&token=1905477219/someother/stuff - in this case "1905477219"

and

&token=xyzbacsfhsaof - in this case "xyzbacsfhsaof" .. like so

But it's not working. Can any one can help me?

Thanks all, this is working fine for me:

var reg = window.location.href.match(/token=([^\/]*)/)[1];

You can use this pattern to match any token with a Latin letter or decimal digit:

/token=([a-z0-9]*)/

Or this which will allow the token to contain any character other than /:

/token=([^\/]*)/

Note that unless you expect to capture multiple tokens, the global modifier (g) is not necessary.

@3gwebtrain You just have to change where you put the parenthesis; see my updated answer.

I tested, still i am getting like this: "token=1905477219" - instead "1905477219"

@3gwebtrain How are you getting that value? /token=([a-z0-9]*)/.exec("token=1905477219")[1] will result in "1905477219".

it works fine to me: window.location.href.match(/token=([^\/]*)/)[1];

/token=(\w*)/g

without the token

/token=(\w*)/.exec("token=1905477219")[1]
/token=(\w*)/.exec("token=1905477219/somestuff")[1]
/token=(\w*)/.exec("somestuf/token=1905477219")[1]
/token=(\w*)/.exec("somestuf/token=1905477219/somestuff")[1]

// all will return 1905477219

this will capture letters, numbers and underscores while stopping at the forward slash if present
