Current URL hashchange event append new hash to target URL and link out to it

Question

I have a page ex: test123.com/go#1 on that page if the hash changes ex: test123.com/go#2 I'd like to append the new hash value to a target URL and link out to it: test123.com/gopage2#2

Here's the code I've tried so far:

var url = window.location.href;
var res = url.split("#");
var hash = "#" + res[1];
$(window).on('hashchange', function() {
  window.location = 'test123.com/gopage2' + hash;
});

When the hash changes nothing happens... Any ideas?

Assuming you meant to update url, res, and hash in the event handler, and use the hash in the new URL, try this:

$(window).on('hashchange', function() {
  var url = window.location.href;
  var res = url.split("#");
  var hash = "#" + res[1];
  window.location = 'test123.com/gopage' + res[1] + hash;
});
