Answer 1

If you are doing extensive url manipulations, then you shoud check out JQuery URL plugin.

To access the params in url hashes

    $.url('http://www.google.com/#hfh=fdg&hash=value2x').fparam('hash');

or if its current url

    $.url().fparam('hash');

Hope it helps

Answer 2

How about

location.hash.split('hash=')[1].split('&')[0]

This will split the hash at hash= and take the value after hash= and before any other argument .

Answer 3

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

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

Answer 4

The URLSearchParams class can be reused for this purpose.

var urlParams = new URLSearchParams(window.location.hash.replace("#","?"));
var hash = urlParams.get('hash');

Answer 5

location.parseHash = function(){
   var hash = (this.hash ||'').replace(/^#/,'').split('&'),
       parsed = {};

   for(var i =0,el;i<hash.length; i++ ){
        el=hash[i].split('=')
        parsed[el[0]] = el[1];
   }
   return parsed;
};

var obj= location.parseHash();
    obj.hash;  //fdg 
    obj.hfh;   //value2x

Answer 6

Split on & and then on =:

pairs = location.hash.substr(1).split('&').map(function(pair) {
    var kv = pair.split('=', 2);
    return [decodeURIComponent(kv[0]), kv.length === 2 ? decodeURIComponent(kv[1]) : null];
})

Here pairs will be an array of arrays with the key at 0 and the value at 1:

[["hfh","fdg"],["hash","value2x"]]
