Get the current URL via JavaScript and change url to short

Example if url is like this : 

http://localhost:8080/someapplication/?token=sUyJhbGciiOiJIUzI1NiJ9.eyJleHAiOjE0NjYxNzIxNTIs1NiJ9.eyJleHAiOjE0NjYInN1YiI6ImthZ2FtaS1hdXRoLXRpY2tldCIsImlzcyI6ImFkbWluIiwicm9sZSI6ImFkbWluIn0.d50P0r2dyeB-XyOG7I-daRp2Pu1OzaBxwisS4Et_rYI&service=auth#/somepage

and output URL to be : http://localhost:8080/someapplication/#/somepage

working code through javascript below : 

/*URL change start*/
if (history.pushState) {
    var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?token=/';
    window.history.pushState({path:newurl},'',newurl);
}
$(window).bind('hashchange', function() {
/* url change code here */
if (window.location.search.match("?token=")){
     var newHash = "/" + window.location.search;
var newHash = "/" ;
     if (window.history.replaceState){
       window.history.replaceState( {}, "", window.location.toString().replace(window.location.search, ""));
     }     
   }
});
function hashHandler(){
    this.oldHash = window.location.hash;
    this.Check;
    var that = this;
    var detect = function(){
        if(that.oldHash!=window.location.hash){
            //alert("HASH CHANGED - new has" + window.location.hash);
            that.oldHash = window.location.hash;
        }
    };
    this.Check = setInterval(function(){ detect() }, 100);
}
var hashDetection = new hashHandler();
/*URL change end*/

JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows:

var currentLocation = window.location;

Basic Structure of a URL

<protocol>//<hostname>:<port>/<pathname><search><hash>

1. Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
2. hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.com. A server provides services using the name of the host.
3. port -- A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
4. pathname -- The path gives info about the specific resource within the host that the Web client wants to access. For example, /index.html.
5. query -- A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).
6. hash -- The anchor portion of a URL, includes the hash sign (#).

With these Location object properties you can access all of these URL components

1. hash - Sets or returns the anchor portion of a URL.
2. host - Sets or returns the hostname and port of a URL.
3. hostname - Sets or returns the hostname of a URL.
4. href - Sets or returns the entire URL.
5. pathname - Sets or returns the path name of a URL.
6. port - Sets or returns the port number the server uses for a URL.
7. protocol - Sets or returns the protocol of a URL.
8. search - Sets or returns the query portion of a URL
