Question

On my web app, I take a look at the current URL, and if the current URL is a form like this:

http://www.domain.com:11000/invite/abcde16989/root/index.html

-> All I need is to extract the ID which consists of 5 letters and 5 numbers (abcde16989) in another variable for further use.

So I need this:

var current_url = "the whole path, not just the hostname";

if (current_url has ID)
    var ID = abcde16989;

Answer 1

You could always use split using / as the delimiter if the ID is always going to be in the same position, eg

var parts = current_url.split('/');
var id = parts[4];

Though your requirement of matching “5 letters and 5 numbers” really does suit a regex match.

var id = current_url.match(/[a-zA-Z]{5}[0-9]{5}/); // returns null if not found
