Answer 1

This should work:

var mySubString = str.split('user').pop().split('/')[1];

Answer 2

Here is one more solution. First split the string with separator / .

Suppose that should be either user or users in the result array.

Property indexOf of absent element equals -1. And 'abc' (or smth else) will always be the next to user|users.

So, index of 'abc' will be indexOf(present element) + indexOf(absent element) + 2 . Thus it's simplest way to find 'abc'

var str = '<span><a href="domain.com/user/abc/"></span>';
var s = str.split('/');
s = s[s.indexOf('user') + s.indexOf('users')+2]

Answer 3

Assuming only user is variable, you can split for all '/' characters.

var str = '<span><a href="domain.com/user/abc/"></span>';
var s = str.split('/');
console.log(s[2]);
