Redirection using javascript

Question

I have an ASP.NET MVC 5 application in which I'd like to perform a redirection using Javascript:

var sPageURL = decodeURIComponent(window.location);
console.log(sPageURL);
var lengthUrl = sPageURL.split('/').length;
var NewUrl = '';
sPageURL.split('/').forEach(function(item, index) {
  if (index < lengthUrl - 2) NewUrl += item;
  if (index == lengthUrl - 1) {
    if (item == "Organisateur") NewUrl += sPageURL.split('/')[lengthUrl - 2];
  }
});
console.log(NewUrl);
window.location = NewUrl;

I get as output:

http://localhost:31569/Event/2

http://localhost:31569/Event/localhost:31569

The problem is that the new URL is concatenated with the old one: I'd like http://localhost:31569/Event/2 be replaced by localhost:31569.

I tried window.location = , window.location.href = and window.location.replace and I get the same result .

So I need to know:

What is the reason of this problem ?
How can I fix it?

Why don't you just do window.location = "/" if you want to navigate to the root of the URL? — Kian Cross

Using window.location = "/" should navigate to the host name of the web page, which I think is what you're trying to do.

The problem you are having sounds like you have not included the protocol (http:// or https://) in front of the URL you want to navigate to.
