I am trying to remove everything after the "?" in the browser url on document ready.
Here is what I am trying:
jQuery(document).ready(function($) {
var url = window.location.href;
url = url.split('?')[0];
});
I can do this and see it the below works:
jQuery(document).ready(function($) {
var url = window.location.href;
alert(url.split('?')[0]);
});
TL;DR
1- To modify current URL and add / inject it (the new modified URL) as a new URL entry to history list, use pushState:
window.history.pushState({}, document.title, "/" + "my-new-url.html");
2- To replace current URL without adding it to history entries, use replaceState:
window.history.replaceState({}, document.title, "/" + "my-new-url.html");
3- Depending on your business logic, pushState will be useful in cases such as:
you want to support the browser's back button
you want to create a new URL, add/insert/push the new URL to history entries, and make it current URL
allowing users to bookmark the page with the same parameters (to show the same contents)
to programmatically access the data through the stateObj then parse from the anchor
As I understood from your comment, you want to clean your URL without redirecting again.
Note that you cannot change the whole URL. You can just change what comes after the domain's name. This means that you cannot change www.example.com/ but you can change what comes after .com/
www.example.com/old-page-name => can become => www.example.com/myNewPaage20180322.php
Background
We can use:
1- The pushState() method if you want to add a new modified URL to history entries.
2- The replaceState() method if you want to update/replace current history entry.
.replaceState() operates exactly like .pushState() except that .replaceState() modifies the current history entry instead of creating a new one. Note that this doesn't prevent the creation of a new entry in the global browser history.
.replaceState() is particularly useful when you want to update the
state object or URL of the current history entry in response to some
user action.
Code
To do that I will use The pushState() method for this example which works similarly to the following format:
var myNewURL = "my-new-URL.php";//the new URL
window.history.pushState("object or string", "Title", "/" + myNewURL );
Feel free to replace pushState with replaceState based on your requirements.
You can substitute the paramter "object or string" with {} and "Title" with document.title so the final statment will become:
window.history.pushState({}, document.title, "/" + myNewURL );
Results
The previous two lines of code will make a URL such as:
https://domain.tld/some/randome/url/which/will/be/deleted/
To become:
https://domain.tld/my-new-url.php
Action
Now let's try a different approach. Say you need to keep the file's name. The file name comes after the last / and before the query string ?.
http://www.someDomain.com/really/long/address/keepThisLastOne.php?name=john
Will be:
http://www.someDomain.com/keepThisLastOne.php
Something like this will get it working:
//fetch new URL
//refineURL() gives you the freedom to alter the URL string based on your needs.
var myNewURL = refineURL();
//here you pass the new URL extension you want to appear after the domains '/'. Note that the previous identifiers or "query string" will be replaced.
window.history.pushState("object or string", "Title", "/" + myNewURL );
//Helper function to extract the URL between the last '/' and before '?'
//If URL is www.example.com/one/two/file.php?user=55 this function will return 'file.php'
//pseudo code: edit to match your URL settings
function refineURL()
{
//get full URL
var currURL= window.location.href; //get current address
//Get the URL between what's after '/' and befor '?'
//1- get URL after'/'
var afterDomain= currURL.substring(currURL.lastIndexOf('/') + 1);
//2- get the part before '?'
var beforeQueryString= afterDomain.split("?")[0];
return beforeQueryString;
}
UPDATE:
For one liner fans, try this out in your console/firebug and this page URL will change:
window.history.pushState("object or string", "Title", "/"+window.location.href.substring(window.location.href.lastIndexOf('/') + 1).split("?")[0]);
This page URL will change from:

Note: as Samuel Liew indicated in the comments below, this feature has been introduced only for HTML5.
An alternative approach would be to actually redirect your page (but you will lose the query string `?', is it still needed or the data has been processed?).
window.location.href = window.location.href.split("?")[0]; //"http://www.newurl.com";
Note 2:
Firefox seems to ignore window.history.pushState({}, document.title, ''); when the last argument is an empty string. Adding a slash ('/') worked as expected and removed the whole query part of the url string.
Chrome seems to be fine with an empty string.
These are all misleading, you never want to add to the browser history unless you want to go to a different page in a single page app. If you want to remove the parameters without a change in the page, you must use:
window.history.replaceState(null, null, window.location.pathname);
I belive the best and simplest method for this is:
var newURL = location.href.split("?")[0];
window.history.pushState('object', document.title, newURL);
a simple way to do this, works on any page, requires HTML 5
// get the string following the ?
var query = window.location.search.substring(1)
// is there anything there ?
if(query.length) {
// are the new history methods available ?
if(window.history != undefined && window.history.pushState != undefined) {
// if pushstate exists, add a new state to the history, this changes the url without reloading the page
window.history.pushState({}, document.title, window.location.pathname);
}
}
I wanted to remove only one param success. Here's how you can do this:
let params = new URLSearchParams(location.search)
params.delete('success')
history.replaceState(null, '', '?' + params + location.hash)
This also retains #hash.
URLSearchParams won't work on IE, but being worked on for Edge. You can use a polyfill or a could use a naïve helper function for IE-support:
function take_param(key) {
var params = new Map(location.search.slice(1).split('&')
.map(function(p) { return p.split(/=(.*)/) }))
var value = params.get(key)
params.delete(key)
var search = Array.from(params.entries()).map(
function(v){ return v[0]+'='+v[1] }).join('&')
return {search: search ? '?' + search : '', value: value}
}
This can be used like:
history.replaceState(
null, '', take_param('success').search + location.hash)
Better solution :
window.history.pushState(null, null, window.location.pathname);
if I have a special tag at the end of my URL like: http://domain.com/?tag=12345
Here is the below code to remove that tag whenever it presents in the URL:
<script>
// Remove URL Tag Parameter from Address Bar
if (window.parent.location.href.match(/tag=/)){
if (typeof (history.pushState) != "undefined") {
var obj = { Title: document.title, Url: window.parent.location.pathname };
history.pushState(obj, obj.Title, obj.Url);
} else {
window.parent.location = window.parent.location.pathname;
}
}
</script>
This gives the idea to remove one or more (or all) parameters from URL
With window.location.pathname you basically get everything before '?' in the url.
var pathname = window.location.pathname; // Returns path only
var url = window.location.href; // Returns full URL
None of these solutions really worked for me, here is a IE11-compatible function that can also remove multiple parameters:
/**
* Removes URL parameters
* #param removeParams - param array
*/
function removeURLParameters(removeParams) {
const deleteRegex = new RegExp(removeParams.join('=|') + '=')
const params = location.search.slice(1).split('&')
let search = []
for (let i = 0; i < params.length; i++) if (deleteRegex.test(params[i]) === false) search.push(params[i])
window.history.replaceState({}, document.title, location.pathname + (search.length ? '?' + search.join('&') : '') + location.hash)
}
removeURLParameters(['param1', 'param2'])
var currURL = window.location.href;
var url = (currURL.split(window.location.host)[1]).split("?")[0];
window.history.pushState({}, document.title, url);
This will be a cleaner way to clear only query string.
//Joraid code is working but i altered as below. it will work if your URL contain "?" mark or not
//replace URL in browser
if(window.location.href.indexOf("?") > -1) {
var newUrl = refineUrl();
window.history.pushState("object or string", "Title", "/"+newUrl );
}
function refineUrl()
{
//get full url
var url = window.location.href;
//get url after/
var value = url = url.slice( 0, url.indexOf('?') );
//get the part after before ?
value = value.replace('#System.Web.Configuration.WebConfigurationManager.AppSettings["BaseURL"]','');
return value;
}
To clear out all the parameters, without doing a page refresh, AND if you are using HTML5, then you can do this:
history.pushState({}, '', 'index.html' ); //replace 'index.html' with whatever your page name is
This will add an entry in the browser history. You could also consider replaceState if you don't wan't to add a new entry and just want to replace the old entry.
a single line solution :
history.replaceState && history.replaceState(
null, '', location.pathname + location.search.replace(/[\?&]my_parameter=[^&]+/, '').replace(/^&/, '?')
);

Here is an ES6 one liner which preserves the location hash and does not pollute browser history by using replaceState:
(l=>{window.history.replaceState({},'',l.pathname+l.hash)})(location)
Running this js for me cleared any params on the current url without refreshing the page.
window.history.replaceState({}, document.title, location.protocol + '//' + location.host + location.pathname);
Here is how can specific query param be removed (even if repeated), without removing other query params:
const newUrl = new URL(location.href);
newUrl.searchParams.delete('deal');
window.history.replaceState({}, document.title, newUrl.href);
In Javascript:
window.location.href = window.location.href.split("?")[0]
I am writing a simple if else if function. If prevPage contains any of 'accounts.google.com' redirect to homepage, else if not from 'accounts.google.com' redirect to login, as simple as that. I only need to detect if it contains 'accounts.google.com' but sometimes the url path is wildcard. if the url is 'accounts.google.com/blablabla' the if statement is at loss and not working
You can simply use URL api and check if host includes google or not
let urls = ['https://accounts.google.co.id/accounts/SetSID', 'https://accounts.google.com/signin/oauth/oauthchooseaccount=certainrandomparameters', 'https://accounts.google.com/blabla', 'google.com', 'xyz']
let domainDetector = (str) => {
let newStr = /^https?:\/\//i.test(str) ? str : 'http://' + str
let url = new URL(newStr)
console.log(url.host.includes('google'))
}
urls.forEach(domainDetector)
I'm trying to get three values from a front-end form in JavaScript and then passing those values to the Laravel controller.
I can get two values (Key and Id) but I cannot get the third value because it is a URL. If I comment the URL variable then I'm getting the rest of the two values (Key and Id) but if I'm passing the URL along other two values then I'm not getting anything in my controller.
I have tried these two JavaScript methods encodeURIComponent() and encodeURI() to encode the https URL given but still no luck.
This is my code in JavaScript:
let get_url = $("#get-url").val();
let get_key = $("#get-key").val();
let get_id = $("#get-area").data('getId');
toastr.remove();
if (get_key) {
var req = new Image();
req.src = api_url + 'senddata/' + get_id + '/' + get_key + '/' + get_url;
console.log(req.src);
toastr.success(MEASURE.UTILITIES.translate("success_request_successfully_sent"));
$("#btn-send-data-request").hide();
$("#block_get_url").hide();
$("#block_get_key").hide();
$("#csv_get_request_message").show();
} else {
toastr.error(MEASURE.UTILITIES.translate("error_enter_valid_data"));
}
Your get_url contains a url, which i believe has https:// or http://
This is a problem when you are adding to the API URL you are constructing as adding more / changes the ROUTE.
For example your API URL expects req.src = api_url + 'senddata/' + get_id + '/' + get_key + '/' + get_url;
which is something like http://www.laravel.com/api/senddata/123/123/urlhere but you are making is something like http://www.laravel.com/api/senddata/123/123/http://urlhere which means you are altering the ROUTE.
To solve that you can URL Encode the URL before passing it.
Change your code to this should work : let get_url = encodeURIComponent($("#get-url").val());

I'm trying to reload a page with an appended variable in the URL, deviceID. It shows up in "realtime" div just fine. What am I doing wrong?:
document.getElementById("realtime").innerHTML = "<pre>"+JSON.stringify(msg)+"</pre>";
var obj = jQuery.parseJSON(JSON.stringify(msg));
var deviceId = obj.deviceId;
var pathname = window.location.pathname;
var pathAppend = pathname + "?deviceId=" + deviceId;
window.location.reload(pathAppend);
It's because you're using window.location.reload incorrectly. reload accepts a boolean which:
when it is true, causes the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache. - MDC
You should do something like:
var query = window.location.search, deviceParam = "deviceId=" + deviceId;
//if there is a query string, append it, otherwise construct the query string.
query += (query === "" ? "?" : "&") + deviceParam;
window.location.search = query; // page should reload
