Trying to match Javascript regex group after slash and other optional slash and rest of string

Question

How to match some-blog-slug in all scenarios below:

/blog/some-blog-post-slug/whatever/anything (CASE 0)
/blog/some-blog-post-slug/whatever (CASE 1)
/blog/some-blog-post-slug/ (CASE 2)
/blog/some-blog-post-slug (CASE 3)

I'm trying: ^/\/blog\/([^\/]+)/

But it's not working at all.

I need to match some-blog-post so I can extract it from the string.

PS.: Sorry to post another REGEX question here on SO.

I think it works. Did you enable the global flag? `g` at the right top of regex101 https://regex101.com/r/nVUh47/1 — The fourth bird, Sep 12 '19 at 15:55

Try out this code using exec() and substring() method .

var re = /\//g,
  str = "/blog/some-blog-post-slug/whatever/anything"; //You can try out all the cases you mentioned in the question . 
var arr = [];
while ((match = re.exec(str)) != null) {
  arr.push(match.index);
  console.log("match found at " + match.index);
}
console.log(arr)
if (arr.length >= 3) {
  var str = str.substring(arr[1] + 1, arr[2]);
  console.log(str)
} else {
  var str = str.substring(arr[1]);
  console.log(str)
}

Thanks! I've thought of that. But even though I hate regex, I really think it's much cleaner to use it. – cbdeveloper Sep 12 '19 at 16:07

@PushprajsinhChudasama you can turn your code into a [`running snippet`](https://stackoverflow.blog/2014/09/16/introducing-runnable-javascript-css-and-html-code-snippets/) – Code Maniac Sep 12 '19 at 16:18
