Hash retrieval from URL

Question

I am trying to setup a form which grabs the hash from the url, then uses that value to determine what radio inputs to check. The latter part is working, but i cannot get the hash retrieval to work.

var url = document.referrer;
var dec= decodeURIComponent(url.replace(/\+/g, '%20'));
var hash = url.substring(url.indexOf('?')+1);
var hash = decodeURI(hash);

In firefox console, i try 'console.log(hash)', and simply get a Reference Error saying that 'hash is not defined'.

The entire script is here if needed - http://pastebin.com/Yq9NbHyz

What exactly do you mean by "hash"? At first I thought you meant the fragment identifier (`#foo`) but your code is looking for `?`. — melpomene, Jan 04 '17 at 13:45
... what? What do you mean, aesthetic reasons? They're different characters! — melpomene, Jan 06 '17 at 11:37

Because hash is not global variable. Use window.location.hash or location.hash

If you meant adding it in the if statement, then it solved the reference error, but it is still saying that 'hash' is undefined. Why would this be? – Jake6192 Jan 06 '17 at 09:24
