How can I get a value from an URL?

Question

Asuming I have something like

var url = 'http://stackoverflow.com/questions/24a34b83c72/js-regex-get-values-between-two-characters'

How could I get the 24a34b83c72 ID using pure javascript? I know that it's always after the questions/ part and that regardless if it contains a number or symbol, it needs to end before the next /. I tried things like;

url.substring(url.lastIndexOf('questions/'))

But that resulted in the entire thread after it. I tried regular expresions but the closest I got to is:

var regex = /"details\/"[a-zA-Z0-9]+"\/"/

Can anyone help me?

Answer 1

You could group everything after questions/ and before the next /, like so:

url.match(/questions\/([^/]+)/)[1]

You can see the output of url.match(..) is this:

["questions/24a34b83c72", "24a34b83c72"]

The second item is there because of the parenthesis around [^/]+, so you access it with url.match(..)[1].
