javascript - How to get #hash value in a URL in JS

Question

For example, I have a URL as :

http://www.google.com/#hash=value2x

I want a js code to return just value2x. I tried location.hash.split('=')[1] but that results the first hash value like if url is

http://www.google.com/#hfh=fdg&hash=value2x

It returns fdg&hash. I want just the value of hash.

NO jQuery Please.

Thanks for the help in advance.

function getHashValue(key) {
  var matches = location.hash.match(new RegExp(key+'=([^&]*)'));
  return matches ? matches[1] : null;
}

// usage
var hash = getHashValue('hash');
