javascript window.location not working

I am new to javascript, and stuck on this problem. I am trying to have the url query string change based on which checkbox checked. But I seem to have some issue with window.location, Some of the JavaScript is below
var urltest= window.location.pathname;
var urltest2 = window.location.host;
var currentURL = urltest2 + urltest;
url = currentURL + "?" + arr_opts.join('&');
document.getElementById('myurl').innerHTML = url;
//window.location.href = url;
window.location = url;
The window.location does not work here, but when I change var currentURL to
var currentURLL = window.location.href;
it is work, but not with
var urltest= window.location.pathname;
var urltest2 = window.location.host;
var currentURL = urltest2 + urltest;
I need window.location to point page to the currentURL above.
Any help would be appreciated.

You're not providing a protocol, so the location.href change is being treated as "go to this relative path from the current location", i.e. on this page
window.location = window.location.host + window.location.pathname;
// takes us to

Do one of the following
Provide a protocol so it knows it is an absolute URI,
window.location = window.location.prototcol + '//' + window.location.host + window.location.pathname + '?foo=bar';
Tell it to re-use the current protocol but work as an absolute URI
window.location = '//' + window.location.host + window.location.pathname + '?foo=bar';
Provide an origin (instead of host)
window.location = window.location.origin + window.location.pathname + '?foo=bar';
Tell it to re-use the same origin but work as an absolute path
window.location = window.location.pathname + '?foo=bar';
Just update the query
window.location = '?foo=bar';
Always choose the most simple option to make your life easier if you ever need to debug, i.e. if you can assume you will always want the same protocol, host and path, just update the query.
Useful knowledge
Starting a URL with..
// means same protocol
/ means same origin
? means same path
# means same query (will not re-load)

The pathname is going to be something like /questions/35254564/javascript-window-location-not-working, and the host is something like stackoverflow.com. If you put those together with code like yours, you get
stackoverflow.com/questions/35254564/javascript-window-location-not-working
That's clearly not correct; the host looks like part of the pathname. You can use protocol and port if you really feel the need to reconstruct the URL from its constituent parts, but using the href seems simpler if all you want to do is add a query string.

history.pushState how can I get rid of get parameters?

I am using
history.pushState('id','myTitle','myURL');
to manipulate the displayed URL and the history stack.
At some point I am pushing get parameters like so:
history.pushState('id','myTitle','?mySubLinkedStuff=hotSubLinkedStuff');
Now when I do
history.pushState('id','myTitle','#justSomeHashtag');
it produces http://example.com?mySubLinkedStuff=hotSubLinkedStuff#justSomeHashtag
I can also overwrite the value of mySubLinkedStuff but not seem to be able to get rif of it alltogether.
Desired result:
http://example.com#justSomeHashtag or http://example.com/#justSomeHashtag
and obviously I don't want to make the whole roundtrip over the server and I also want to avoid using absolute path or URL to keep the project portable.

As NimrodArgov rightly remarked: overwriting existing get-parameter strings works if you
push the full URL.
So for ensuring portability of the app (keep it usable on various domains) I did this:
history.statePush(document.location.origin + window.location.pathname + '#myHashValue');
Works perfectly well and fast.

To push current address without GET parameters :
history.pushState("id", "myTitle",
location.protocol + "//" + location.host +
location.pathname + location.hash
);
Other than that ;
To push a hash change I could do :
history.pushState("id", "myTitle",
location.protocol + "//" + location.host +
location.pathname + location.search + "#myHashHere"
);
To push a query change I could do :
history.pushState("id", "myTitle",
location.protocol + "//" + location.host +
location.pathname + "?my=query&over=here" + location.hash
);

bookmarklet to swap URL with URL/directory

I'm trying to create a bookmarklet (something I've never done) that will read the URL and check if it ends with "/directory". If it does, I want to remove "/directory". If it doesn't, I want to add it.
I'm using the following to successfully append the directory to the URL, but I don't know how to check if it's already there or delete it if it is.
javascript: window.location = window.location.protocol + '//' + window.location.hostname + window.location.pathname + '/directory';

This will do it:
var URL = window.location.href; window.location.href = /\/directory$/.test(URL) ? URL.replace(/\/directory$/, '') : URL + '/directory';
Checks if the url ends with /directory if does, removes it, else adds it.

Current URL without parameters, hash, http(s)://

I'm looking for a neat way of getting the URL of the current document in Javascript.
The URL should be clean of parameters (?parameter1=bla&parameter2=bla)
The URL should be clean of hash tags (#jumppoint)
http/https should be removed/consolidated into http
I know i can get the current URL with location.href and then use some regular expressions to clean it up but maybe there is a nicer/cleaner solution for getting rid of the junk?

There are many other parameters than the href in window.location. See full reference here: https://developer.mozilla.org/en/DOM/window.location
What you are looking for as a starter might be the window.location.hostname:
"the host name (without the port number or square
brackets)."
From the example URL http://[www.example.com]:80/search?q=devmo#test the hostname will be www.example.com.
If you also want to include the path and force a http:// protocol, try:
'http://' + window.location.hostname + window.location.pathname;
As a side note, a nifty trick to get the same parameters from another URL than the window.location is to create an empty anchor:
var a = document.createElement('a');
a.href = 'http://www.example.com:80/search?q=devmo#test';
console.log('http://' + a.hostname + a.pathname);

None of the given answers address the fact that the protocol can be http or https as in the OPs title. To accommodate this I suggest:
document.location.protocol +"//"+ document.location.hostname + document.location.pathname

The Location object got what you need
window.location.hostname + window.location.pathname

You have document.location object, so:
var oLoc = document.location,
sUrl = oLoc.protocol + oLoc.hostname;
// or "http://" + oLoc.hostname

You can use these replacement functions to remove the hash and search arguments and normalize https to http:
url = url.replace(/#[^#]*$/, "").replace(/\?[^\?]*$/, "").replace(/^https:/, "http:");
Or, if all you really want is the domain and path, you can just use this:
window.location.hostname + window.location.pathname

Please try this snippet:
if (!window.location.origin){
// For IE
window.location.origin = window.location.protocol + "//" + (window.location.port ? ':' + window.location.port : '');
}
url = window.location.origin + window.location.pathname;
document.write('Origin url: ' + url);

This page indicates that you could probably use window.location.host to get the part you're actually interested in. I haven't tested it, though.

Try:
window.location.hostname;

Get url with javascript

I want to get the url with javascript. But I just need http://www.mysite.com, without any parameters behind it. any idea how to get that?

Use this:
var url = window.location.protocol + "//" + window.location.host;

window.location.hostname

try
window.location.protocol+'//'+window.location.hostname
