Is it possible to get the last path of a url using RegExp

Question

Is possible to get the last value in URL results in the following string:

http://www.example.com/snippets/rBN6JNO/

My RegEx is matching the whole string

\/.+\/

It matches:

//www.example.com/snippets/rBN6JNO/

I want to get the last value:

rBN6JNO

Or should I use another method?

use split by "/" and access last/last second value – Vinod Louis Feb 03 '17 at 10:53 — Vinod Louis, Feb 03 '17 at 10:53

You can split your URL with /, and then access the last object of the splited URL.

Try the following:

var url = "http://www.example.com/snippets/rBN6JNO";
var splitedUrl = url.split('/');   
var lastPath = splitedUrl[splitedUrl.length - 1]; //rBN6JNO

Perhaps, it is a good idea to remove any trailing `/` before splitting: `url.replace(/\/+$/, '').split('/')`. – Wiktor Stribiżew Feb 03 '17 at 10:56
Yep, could be a good idea. It will make `splitedUrl[]` simpler. – Mistalis Feb 03 '17 at 10:58

Try this using javaScript you can do it,

var URL_STRING = 'http://www.example.com/snippets/rBN6JNO/'
URL_STRING.split('/').slice(3)

/([a-z\d]+)(\/*|)$/i

And see "$1"

you have to check whether it has parameter or not. \?+ – ian park Feb 03 '17 at 11:54

To avoid to create an array, you can do this with string methods only - using substr() and lastIndexOf():

s = s.replace(/\/$/,"");
console.log(s.substr(s.lastIndexOf("/") + 1));
