Validate SoundCloud URL via javascript regex

Question

I have 2 urls from soundcloud that I would like to get everything after the .com/(or).sc/, I don't understand regex at all, I could do the javascript match/replace, only problem is the http vs https

https://soundcloud.com/ilyao/lyao-lj-mtx-and-lj-mtxs-hair

http://snd.sc/1cvgIjv

Any help would be much appreciated.

Here's what I've got, not sure how to do the https of the replace or if this is the best way to approach this...

function getSoundCloudInfo(url){
    return url.replace("https://soundcloud.com/", "").replace("http://snd.sc/", "");
}

Answer 1

function getSoundCloudInfo(url){
  var regexp = /^https?:\/\/(soundcloud\.com|snd\.sc)\/(.*)$/;
  return url.match(regexp) && url.match(regexp)[2]
}

Answer 2

It is too late, but...

Don't forget about:

1. mobile version (m. after http(s)://)
2. possible slash at the end
3. with or without SSL/TLS, so it can be http or https
4. with or without www

So, full regex is:

^(https?:\/\/)?(www.)?(m\.)?soundcloud\.com\/[\w\-\.]+(\/)+[\w\-\.]+/?$

Answer 3

((https:\/\/)|(http:\/\/)|(www.)|(m\.)|(\s))+(soundcloud.com\/)+[a-zA-Z0-9\-\.]+(\/)+[a-zA-Z0-9\-\.]+
