Why is window.location.href appending url again - javascript

In my code, I'm assigning the following:
window.location.href = "www.example.com/test";
But when the page actually loads, the browser URL is www.example.com/test/www.example.com/test. I'm not appending anything to the URL, and I'm not sure how its appending the URL again.

I think you're missing the "http" or "https" part. Have you tried the following?
window.location.href = "https://www.example.com/test";
or
window.location.href = "http://www.example.com/test";

Because you forgot the protocol. If you omit the protocol, window.location.href thinks you are trying to access a folder with the name of www.example.com, relative to the page you are currently on.
window.location.href="http://www.example.com/test/" will ensure that you access the external website www.example.com.
Hope this helps! :)

Check the way you are constructing the url, sometimes we miss the host, or enter the incorrect path
A safe way to change the URl is by making changes in the exisiting URL
first get the existing URL by
let exisitingURl = window.location.href;
now manipulate this url, for eg
exisitingURL = exisitingURL.replace('/auth', '/gateway');
now go to the url by
window.location.href = existingURL;

Redirect to different URL when current URL contains some string

I have a requirement wherein I need to redirect my page to a different URL when my current URL contains some string.
For instance,
If my current URL contains www.testdomain.com or www.testdomain.com/web/region then it should redirect to www.testdomain.com/group/region. I tried the below code but it returns "The requested resource could not be found -- https://www.testdomain.com/web/region/testdomain.com/group/region".
$(document).ready(function() {
if (window.location.href.indexOf("web/region") > -1) {
window.location.href=window.location.hostname+'/group/region';
}
})
It is adding the URL twice here. But when I pass the direct URL window. location.href="www.testdomain.com/group/region" it is working.
Can someone guide me on how do I force redirect my page if the URL contains www.testdomain.com or www.testdomain.com/web/region?
Thanks
Start with // so that the browser knows it's not a relative URI:
window.location.href = '//' + window.location.hostname+'/group/region';
You can also prepend the protocol:
window.location.href = window.location.protocol + '//' + window.location.hostname+'/group/region';
It's adding the URL twice because browsers interpret /group/region as a relative path, automatically prepending the current domain UNLESS otherwise specified. (Maybe others can explain why window.location.hostname doesn't immediately return, thus preventing the browser from assuming a relative path?)
Example: If you explicitly set a domain, the browser will redirect to it as expected.
window.location.href='http://www.google.com/'
Otherwise, if you take away "www."
window.location.href='google.com/'
Your browser will redirect to "www.testdomain.com/google.com", appending the string.
The fix is simple.
Just delete window.location.hostname+ and it will only return the URL once.
Or... for a better user experience, I would suggest using window.location.replace() which DOES NOT save the current page in session history.(You don't want to go back, just to be redirected again!)
SOLUTION:
Replace your return block with this.
window.location.replace('/group/region')

Javascript How to check if the page opened is Home Page [duplicate]

All I want is to get the website URL. Not the URL as taken from a link. On the page loading I need to be able to grab the full, current URL of the website and set it as a variable to do with as I please.
Use:
window.location.href
As noted in the comments, the line below works, but it is bugged for Firefox.
document.URL
See URL of type DOMString, readonly.
URL Info Access
JavaScript provides you with many methods to retrieve and change the current URL, which is displayed in the browser's address bar. All these methods use the Location object, which is a property of the Window object. You can read the current Location object by reading window.location:
var currentLocation = window.location;
Basic URL Structure
<protocol>//<hostname>:<port>/<pathname><search><hash>
protocol: Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
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.
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.
pathname: The path gives info about the specific resource within the host that the Web client wants to access. For example, /index.html.
search: 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).
hash: The anchor portion of a URL, includes the hash sign (#).
With these Location object properties you can access all of these URL components and what they can set or return:
href - the entire URL
protocol - the protocol of the URL
host - the hostname and port of the URL
hostname - the hostname of the URL
port - the port number the server uses for the URL
pathname - the path name of the URL
search - the query portion of the URL
hash - the anchor portion of the URL
origin - the window.location.protocol + '//' + window.location.host
I hope you got your answer..
Use window.location for read and write access to the location object associated with the current frame. If you just want to get the address as a read-only string, you may use document.URL, which should contain the same value as window.location.href.
Gets the current page URL:
window.location.href
OK, getting the full URL of the current page is easy using pure JavaScript. For example, try this code on this page:
window.location.href;
// use it in the console of this page will return
// http://stackoverflow.com/questions/1034621/get-current-url-in-web-browser"
The window.location.href property returns the URL of the current page.
document.getElementById("root").innerHTML = "The full URL of this page is:<br>" + window.location.href;
<!DOCTYPE html>
<html>
<body>
<h2>JavaScript</h2>
<h3>The window.location.href</h3>
<p id="root"></p>
</body>
</html>
Just not bad to mention these as well:
if you need a relative path, simply use window.location.pathname;
if you'd like to get the host name, you can use window.location.hostname;
and if you need to get the protocol separately, use window.location.protocol
also, if your page has hash tag, you can get it like: window.location.hash.
So window.location.href handles all in once... basically:
window.location.protocol + '//' + window.location.hostname + window.location.pathname + window.location.hash === window.location.href;
//true
Also using window is not needed if already in window scope...
So, in that case, you can use:
location.protocol
location.hostname
location.pathname
location.hash
location.href
To get the path, you can use:
console.log('document.location', document.location.href);
console.log('location.pathname', window.location.pathname); // Returns path only
console.log('location.href', window.location.href); // Returns full URL
Open Developer Tools, type in the following in the console and press Enter.
window.location
Ex: Below is the screenshot of the result on the current page.
Grab what you need from here. :)
Use: window.location.href.
As noted above, document.URL doesn't update when updating window.location. See MDN.
Use window.location.href to get the complete URL.
Use window.location.pathname to get URL leaving the host.
You can get the current URL location with a hash tag by using:
JavaScript:
// Using href
var URL = window.location.href;
// Using path
var URL = window.location.pathname;
jQuery:
$(location).attr('href');
For complete URL with query strings:
document.location.toString()
For host URL:
window.location
// http://127.0.0.1:8000/projects/page/2?name=jake&age=34
let url = new URL(window.location.href);
/*
hash: ""
host: "127.0.0.1:8000"
hostname: "127.0.0.1"
href: "http://127.0.0.1:8000/projects/page/2?username=jake&age=34"
origin: "http://127.0.0.1:8000"
password: ""
pathname: "/projects/page/2"
port: "8000"
protocol: "http:"
search: "?name=jake&age=34"
username: ""
*/
url.searchParams.get('name')
// jake
url.searchParams.get('age')
// 34
url.searchParams.get('gender')
// null
To get the path, you can use:
http://www.example.com:8082/index.php#tab2?foo=789
Property Result
------------------------------------------
window.location.host www.example.com:8082
window.location.hostname www.example.com
window.location.port 8082
window.location.protocol http:
window.location.pathname index.php
window.location.href http://www.example.com:8082/index.php#tab2
window.location.hash #tab2
window.location.search ?foo=789
window.location.origin https://example.com
var currentPageUrlIs = "";
if (typeof this.href != "undefined") {
currentPageUrlIs = this.href.toString().toLowerCase();
}else{
currentPageUrlIs = document.location.toString().toLowerCase();
}

For those who want an actual URL object, potentially for a utility which takes URLs as an argument:
const url = new URL(window.location.href)
https://developer.mozilla.org/en-US/docs/Web/API/URL
Nikhil Agrawal's answer is great, just adding a little example here you can do in the console to see the different components in action:
If you want the base URL without path or query parameter (for example to do AJAX requests against to work on both development/staging AND production servers), window.location.origin is best as it keeps the protocol as well as optional port (in Django development, you sometimes have a non-standard port which breaks it if you just use hostname etc.)
You have multiple ways to do this.
1:
location.href;
2:
document.URL;
3:
document.documentURI;
Use this:
var url = window.location.href;
console.log(url);
In jstl we can access the current URL path using pageContext.request.contextPath. If you want to do an Ajax call, use the following URL.
url = "${pageContext.request.contextPath}" + "/controller/path"
Example: For the page http://stackoverflow.com/posts/36577223 this will give http://stackoverflow.com/controller/path.
The way to get the current location object is window.location.
Compare this to document.location, which originally only returned the current URL as a string. Probably to avoid confusion, document.location was replaced with document.URL.
And, all modern browsers map document.location to window.location.
In reality, for cross-browser safety, you should use window.location rather than document.location.
location.origin+location.pathname+location.search+location.hash;
and
location.href
does the same.
You can get the full link of the current page through location.href
and to get the link of the current controller, use:
location.href.substring(0, location.href.lastIndexOf('/'));
Short
location+''
let url = location+'';
console.log(url);
Getting the current URL with JavaScript :
window.location.toString();
window.location.href
if you are referring to a specific link that has an id this code can help you.
$(".disapprove").click(function(){
var id = $(this).attr("id");
$.ajax({
url: "<?php echo base_url('index.php/sample/page/"+id+"')?>",
type: "post",
success:function()
{
alert("The Request has been Disapproved");
window.location.replace("http://localhost/sample/page/"+id+"");
}
});
});
I am using ajax here to submit an id and redirect the page using window.location.replace. just add an attribute id="" as stated.
let url = new URL(window.location.href);
console.log(url.href);
Use the above code to get the current URL of the website.
or try this - https://bbbootstrap.com/code/get-current-url-javascript-54628697
Firstly check for page is loaded completely in
browser,window.location.toString();
window.location.href
then call a function which takes url, URL variable and prints on console,
$(window).load(function(){
var url = window.location.href.toString();
var URL = document.URL;
var wayThreeUsingJQuery = $(location).attr('href');
console.log(url);
console.log(URL);
console.log(wayThreeUsingJQuery );
});

How can I make a page that look for URL and create a text that refer to the URL?

So it's kind of a dumb question but I'm really wondering how I can make this :
user type www.mydomaine.com/something
page display : something
and it does with anything he type after the domain name
I've no idea how I could do that. I know I can get an info from an URL with jQuery but how can i remove the thing like index.html in the url? My guess would be with the htaccess?
Also, there won't be any other page but this with some design, how can I make sure someone doesn't go anywhere else but on the page that display what he wrote after the domain name?
I hope that's clear, thanks for reading and your answers !
Pierre
When creating an anchor tag and adding an href (or making a URL) I needed the URL to have a protocol (http or https), so I made a validation to add it, and then you can access the parameters of the URL easier.
Also, if you want to remove the / from the pathname you can use a .replace('/', '') when using parser.pathname
For removing index.html from the URL, you can split the path and get only the first element, or the ones you need f.e. parser.pathname.split('/')[0]
var myUrl = "www.mydomaine.com/something"
if (!myUrl.startsWith('http')) myUrl = 'http://' + myUrl;
var parser = document.createElement('a');
parser.href = myUrl;
console.log(parser.pathname);
// Other option
var theUrl = new URL(myUrl);
console.log(theUrl.pathname);

Redirect to url with some addition in the url

Suppose, i've my current url:
http://localhost:3000/contests
after the button press, i am going to redirect to the following url:
http://localhost:3000/contests?keywords=algo
My problem is, i want to redirect to the path with other additional information like:
http://localhost:3000/contests?keywords=algo&show=present
here, the &show=present is added to the redirected url. How can i do that using javascript?
How can i get the redirect url using javascript?
Do this in your button click.
var url=document.URL + "&show=present";
window.location.href = url;
Use document.URL to get the current url.
Hope this will help you!!
location.href = location.href + "?keywords=algo"
also check all the other possibilities with window.location object at MDN

Forcing Javascript Redirection

I am trying to implement what seems to be very simple JavaScript redirection, via the following rudimentary command:
window.location.href = "http://www.somesite.com";
So far so good, it works. I also can do it via the following method:
location.replace("http://www.somesite.com");
No problem here, it works again! The problem comes when I loose the protocol out of the string:
window.location.href = "www.somesite.com";
OR:
location.replace("www.somesite.com");
It just appends the new location to the current url:
www.currentsite.com/www.somesite.com
Of cause, that's not what I want. Is there any way to force the redirect?
One way is to use protocol-relative url like this:
window.location = "//www.somesite.com";
Or
window.location = "//somesite.com";
This way, it would redirect and browser itself will take care of figuring out protocol part eg http or https
Working Example
The protocol is required.
How else would the browser know whether
location.replace("mysite.pl");
was going to a Polish website or a Perl script on the current website?
You could do something like this to add http:// to the URL if it's not already there... although I can't think of a reason for not just including it yourself. Why complicate things?
​function redirect(url) {
if(url.substr(4) != "http")
url = "http://" + url;
window.location.href = url;
}
redirect("www.google.com")
