Regex match string until whitespace Javascript

Question

I want to be able to match the following examples:

www.example.com
http://example.com
https://example.com

I have the following regex which does NOT match www. but will match http:// https://. I need to match any prefix in the examples above and up until the next white space thus the entire URL.

var regx = ((\s))(http?:\/\/)|(https?:\/\/)|(www\.)(?=\s{1});

Lets say I have a string that looks like the following:

I have found a lot of help off www.stackoverflow.com and the people on there!

I want to run the matching on that string and get

www.stackoverflow.com

Thanks!

Answer 1

You can try

(?:www|https?)[^\s]+

Here is online demo

sample code:

var str="I have found a lot of help off www.stackoverflow.com and the people on there!";
var found=str.match(/(?:www|https?)[^\s]+/gi);
alert(found);

Pattern explanation:

  (?:                      group, but do not capture:
    www                      'www'
   |                        OR
    http                     'http'
    s?                       's' (optional)
  )                        end of grouping
  [^\s]+                   any character except: whitespace 
                            (\n, \r, \t, \f, and " ") (1 or more times)
