I have a simple script for replace prameter:
function replaceQueryParam(param, newval, search) {
//condition over accumulation & in url if I use null
if(newval == null){
ampersand = "";
} else{
ampersand = "&";
}
var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
var query = search.replace(regex, "$1").replace(/&$/, '');
return (query.length > 2 ? query + ampersand : "?") + (newval ? param + "=" + newval : '');
}
And I use it:
var str = window.location.search
str = replaceQueryParam('myParam', 'myValue', str)
window.location = window.location.pathname + str
It run perfect, but I want use the function edit to parameters with only one redirect. If I have it in onClick event, I cant use:
var str = window.location.search
str = replaceQueryParam('myParam', 'myValue', str)
window.location = window.location.pathname + str
var str = window.location.search
str = replaceQueryParam('SecondParam', 'null', str)
window.location = window.location.pathname + str
The second parameter I want null (I want delete second parameter from url) - if it by simple.
Thanks and sorry for my English
PS: It can by in jquery
All of my event:
$("#typ span").click(function() {
var url = window.location.href;
//if it exist
if (url.indexOf('typ') > -1){
var str = window.location.search
str = replaceQueryParam('typ', $(this).attr('id'), str)
window.location = window.location.pathname + str
//if its doesnt exist - add new
} else {
if (url.indexOf('?') > -1){
url += '&typ='+$(this).attr('id');
}else{
url += '?typ='+$(this).attr('id');
}
window.location.href = url;
}
});
if click on span I want do this (add or replace "typ") and null other parameter (if it exist) - with only one redirect.
Take a look at the existing URL interface.
Example:
const url = new URL('http://test.com/products?category=bears&page=3');
url.searchParams.set('category', 'puppies');
console.log(url.href); // Result: http://test.com/products?category=puppies&page=3

I want to remove the query string from my URL before I add my URL parameters. Say my site is https://www.abcd.com/test I am appending some parameters to my URL like /def?key=value through javascript. But the page is built as https://www.abcd.com/test?/def?key=value. I want it to be https://www.abcd.com/test/def?key=value Below is my code. Any input is greatly appreciated.
redirectURL: function() {
var currentURL = window.location.href;
var kvp = document.location.search.substr(1).split('&');
if (kvp == '') {
if (currentURL.indexOf("def") == -1){
document.location.search = '/def'+ '?' + 'key' + '=' + 'value';
}else{
document.location.search = '?' + 'key' + '=' + 'value';
}
}
else {
var i = kvp.length; var x; while (i--) {
x = kvp[i].split('=');
if (x[0] == key) {
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if (i < 0) { kvp[kvp.length] = [key, value].join('='); }
document.location.search = kvp.join('&');
}
}
You are appending your URL parameters to the location.search property which is the querystring:
document.location.search = '/def'+ '?' + 'key' + '=' + 'value';
I believe what you want to do is append your URL parameters to the location.href property, but first you will need to separate the existing search string (querystring) from it:
var urlBase = window.location.href.split('?')[0];
window.location.href = urlBase + '/def'+ '?' + 'key' + '=' + 'value';
The following function is designed to replace a variable in the URL.
It works, but I want to make it so that if you pass in a variable that doesn't exist in the URL, it will add it to the URL.
window.setUrlParameter = function(param, value) {
const regExp = new RegExp(param + "(.+?)(&|$)", "g");
const newUrl = window.location.href.replace(regExp, param + "=" + value + "$2");
window.history.pushState("", "", newUrl);
}
There is the function. It takes the param name that you want to replace, and the value you want to set.
As I stated earlier, I want it to be able to not only replace variables, but set them as well.
Thanks!
This function should also be faster than using a regex, modified from this answer.
(The arrow function is just ES6 syntax, you can use normal functions if you want too)
window.setUrlParameter = (param, value) => {
var url = window.location.href;
var hash = location.hash;
url = url.replace(hash, '');
if (url.indexOf(param + "=") >= 0)
{
var prefix = url.substring(0, url.indexOf(param));
var suffix = url.substring(url.indexOf(param));
suffix = suffix.substring(suffix.indexOf("=") + 1);
suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
url = prefix + param + "=" + value + suffix;
}
else
{
if (url.indexOf("?") < 0)
url += "?" + param + "=" + value;
else
url += "&" + param + "=" + value;
}
window.history.pushState(null, null, url + hash);
}
You have the regex, you can just test the url for the same thing, and add it if it isn't there
window.setUrlParameter = function(param, value) {
const regex = new RegExp(param + "(.+?)(&|$)", "g");
const exist = regex.test(window.location.href);
let addQS = window.location.search.length > 0 : '&' : '?';
let newUrl;
if (exist) {
newUrl = window.location.href.replace(regExp, param + "=" + value + "$2");
} else {
newUrl = window.location.href + addQS + param + "=" + value;
}
window.history.pushState("", "", newUrl);
}
I'd highly recommend cleaning this up with RegEx, but you could just check whether or not the href includes the parameter
window.setUrlParameter = function(param, value) {
const regExp = new RegExp(param + "(.+?)(&|$)", "g");
let newUrl = window.location.href.replace(regExp, param + "=" + value + "$2");
if (! window.location.href.includes(param) )
newUrl+='&'+param+'='+value
window.history.pushState("", "", newUrl);
}
Nobody here used the URLSearchParams API, so I thought I'd show you that way:
function modifyLocation( param, value )
{
var qParams = window.location.search.split('?')[0];
var urlParams = new URLSearchParams(qParams);
if( urlParams.has(param) ){
urlParams.delete(param);
}
urlParams.append(param, value);
return window.location.href.split('?')[0] + '?' + urlParams.toString();
}
// To test on CodePen, I used editors = 4, because CodePen has that param
var newUrl = modifyLocation('editors','4');
console.log(newUrl);
// window.history.pushState("", "", newUrl);
I got this function from here in stack to replace url parameters like that :
function replaceUrlParam(paramName, paramValue){
var currentUrl = window.location.href;
var pattern = new RegExp('('+paramName+'=).*?(&|$)')
var newUrl = currentUrl.replace(pattern,'$1' + paramValue + '$2');
if(newUrl == currentUrl){
newUrl = newUrl + (newUrl.indexOf('?')>0 ? '&' : '?') + paramName + '=' + paramValue
}
window.history.pushState('',document.title,newUrl);
return newUrl;
}
www.mysite.com/index.php?id=14&&cat=20
and i use it like that:
replaceUrlParam('id', 15);
like that works fine.
But the problem is it duplicates the id if i use same id which is in the url like that.
replaceUrlParam('id', 14)--will give--->www.mysite.com/index.php?id=14&&cat=20&&id=14
How can i change this function to not give duplicates when its same id ?
Thanks
fiddle here
The if statement in the function explains everything. If the url hasn't changed then it tacks the param/value onto the end. Sounds like you want to also check that the value isn't already in there, like:
if(newUrl == currentUrl && newUrl.indexOf(paramName+'='+paramValue) === -1) {
//...
}
Here's an updated jsfiddle
www.mysite.com/index.php?id=14&&cat=20
and
replaceUrlParam('id', 14)
is trying to repalce id:14 with id:14. So in this case: newUrl == currentUrl will resolve to true.
newUrl = newUrl + (newUrl.indexOf('?')>0 ? '&' : '?') + paramName + '=' + paramValue
will find the index of the '?', which is 24, which is > 0.
So in the end you're doing this:
newUrl = www.mysite.com/index.php?id=15&&cat=20 + paramName + '=' + paramValue
In either scenario, if your (currentUrl == newUrl) == true your concatanation will end up either doing
newUrl = newUrl + '&' + paramName + '=' + paramValue
or
newUrl = newUrl + '?' + paramName + '=' + paramValue
Either way will duplicate your value at the end.
the website i maintain is moving from the standard php url format:
http://example.com/page.php?key=value&key=value...
to a more seo friendly format like this:
http://example.com/page/key/value/key/value...
I was using this function in javascript to add, update/modify the old formatted url string:
function UpdateQueryString(key, value, url) {
if (!url) url = window.location.href;
var re = new RegExp("([?|&])" + key + "=.*?(&|#|$)(.*)", "gi");
if (re.test(url)) {
if (typeof value !== 'undefined' && value !== null)
return url.replace(re, '$1' + key + "=" + value + '$2$3');
else {
return url.replace(re, '$1$3').replace(/(&|\?)$/, '');
}
}
else {
if (typeof value !== 'undefined' && value !== null) {
var separator = url.indexOf('?') !== -1 ? '&' : '?',
hash = url.split('#');
url = hash[0] + separator + key + '=' + value;
if (hash[1]) url += '#' + hash[1];
return url;
}
else
return url;
}
}
This worked perfectly. Now this function highlights the two things im bad at, javascript and regexs. I am trying to modify this function to use slashes, '/' instead of ?&=. This is my first try at it:
function myUpdateQueryString(key, value, url)
{
if (!url) url = window.location.href;
var re = new RegExp("([/])" + key + "(/)(.*)", "gi");
if (re.test(url)) {
if (typeof value !== 'undefined' && value !== null)
return url.replace(re, '$1' + key + "/" + value + '$2$3');
else {
return url.replace(re, '$1$3').replace(/(\/)$/, '');
}
}
else {
if (typeof value !== 'undefined' && value !== null) {
var separator = '/',
hash = url.split('#');
url = hash[0] + separator + key + '/' + value;
if (hash[1]) url += '#' + hash[1];
return url;
}
else
return url;
}
}
This function is getting me very close. It will add new key/values to the url string, but i am having trouble updating/modifying current values in the string.
I think its an easy fix. I am just having trouble wrapping my head around $2$3 in the regex and a few other things.
Thanks
I think i have found the answer
This seems to be working for now:
function UpdateQueryString(key, value, url)
{
if (!url) url = window.location.href;
var re = new RegExp("([/])" + key + "/.*?(/|$)", "gi");
var separator = '/';
if (url.match(re)) {
return url.replace(re, '$1' + key + "/" + value + '$2');
}
else {
return url + separator + key + "/" + value;
}
}
Can anyone see anything wrong with this?
Could you do something like this instead?
url.split('/?|&|=/').join('/');
This should replace all question marks, ampersands, and equal signs in your URL with slashes.
function UpdateQueryString(key, value, url)
{
if (!url) url = window.location.href;
var re = new RegExp("([/])" + key + "/.*?(/|$)", "gi");
var separator = '/';
if (url.match(re)) {
return url.replace(re, '$1' + key + "/" + value + '$2');
}
else {
return url + separator + key + "/" + value;
}
}
This seems to work. Can anyone find anything wrong with this. I am not very good at regexs or javascript
If the &view-all parameter does NOT exist in the URL I need to add it to the end of the URL along with a value. If it DOES exist then I need to be able to just change the value without creating a new URL because it might, or might not, have other parameters before it.
I found this function but I can't get it to work: https://stackoverflow.com/a/10997390/837705
Here is the code I have using the function above (which I can't get to work): http://jsfiddle.net/Draven/tTPYL/4/
I know how to append the parameter and value already:
<div onclick="javascript: window.location.assign(window.location.href+='&view-all=Yes');">Blah Blah</div>
More Info:
If the URL is http://www.domain.com/index.php?action=my_action then the default "&view-all" value would be "Yes" so the URL they would be directed to when they click the button is http://www.domain.com/index.php?action=my_action&view-all=Yes.
If the URL is http://www.domain.com/index.php?action=my_action&view-all=Yes then when they click the button it would change to http://www.domain.com/index.php?action=my_action&view-all=No
EDIT: Please give me examples. I don't know alot of JS, and I just can't think of a way to do it in PHP.
function setGetParameter(paramName, paramValue)
{
var url = window.location.href;
var hash = location.hash;
url = url.replace(hash, '');
if (url.indexOf(paramName + "=") >= 0)
{
var prefix = url.substring(0, url.indexOf(paramName + "="));
var suffix = url.substring(url.indexOf(paramName + "="));
suffix = suffix.substring(suffix.indexOf("=") + 1);
suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
url = prefix + paramName + "=" + paramValue + suffix;
}
else
{
if (url.indexOf("?") < 0)
url += "?" + paramName + "=" + paramValue;
else
url += "&" + paramName + "=" + paramValue;
}
window.location.href = url + hash;
}
Call the function above in your onclick event.
Why parse the query string yourself when you can let the browser do it for you?
function changeQS(key, value) {
let urlParams = new URLSearchParams(location.search.substr(1));
urlParams.set(key, value);
location.search = urlParams.toString();
}
All the preivous solution doesn't take in account posibility of the substring in parameter. For example http://xyz?ca=1&a=2 wouldn't select parameter a but ca. Here is function which goes through parameters and checks them.
function setGetParameter(paramName, paramValue)
{
var url = window.location.href;
var hash = location.hash;
url = url.replace(hash, '');
if (url.indexOf("?") >= 0)
{
var params = url.substring(url.indexOf("?") + 1).split("&");
var paramFound = false;
params.forEach(function(param, index) {
var p = param.split("=");
if (p[0] == paramName) {
params[index] = paramName + "=" + paramValue;
paramFound = true;
}
});
if (!paramFound) params.push(paramName + "=" + paramValue);
url = url.substring(0, url.indexOf("?")+1) + params.join("&");
}
else
url += "?" + paramName + "=" + paramValue;
window.location.href = url + hash;
}
I had a similar situation where I wanted to replace a URL query parameter. However, I only had one param, and I could simply replace it:
window.location.search = '?filter=' + my_filter_value
The location.search property allows you to get or set the query portion of a URL.
To do it in PHP: You have a couple of parameters to view your page, lets say action and view-all. You will (probably) access these already with $action = $_GET['action'] or whatever, maybe setting a default value.
Then you decide depending on that if you want to swich a variable like $viewAll = $viewAll == 'Yes' ? 'No' : 'Yes'.
And in the end you just build the url with these values again like
$clickUrl = $_SERVER['PHP_SELF'] . '?action=' . $action . '&view-all=' . $viewAll;
And thats it.
So you depend on the page status and not the users url (because maybe you decide later that $viewAll is Yes as default or whatever).
Some simple ideas to get you going:
In PHP you can do it like this:
if (!array_key_exists(explode('=', explode('&', $_GET))) {
/* add the view-all bit here */
}
In javascript:
if(!location.search.match(/view\-all=/)) {
location.href = location.href + '&view-all=Yes';
}
though i take the url from an input, it's easy adjustable to the real url.
var value = 0;
$('#check').click(function()
{
var originalURL = $('#test').val();
var exists = originalURL.indexOf('&view-all');
if(exists === -1)
{
$('#test').val(originalURL + '&view-all=value' + value++);
}
else
{
$('#test').val(originalURL.substr(0, exists + 15) + value++);
}
});

Here's a way of accomplishing this. It takes the param name and param value, and an optional 'clear'. If you supply clear=true, it will remove all other params and just leave the newly added one - in other cases, it will either replace the original with the new, or add it if it's not present in the querystring.
This is modified from the original top answer as that one broke if it replaced anything but the last value. This will work for any value, and preserve the existing order.
function setGetParameter(paramName, paramValue, clear)
{
clear = typeof clear !== 'undefined' ? clear : false;
var url = window.location.href;
var queryString = location.search.substring(1);
var newQueryString = "";
if (clear)
{
newQueryString = paramName + "=" + paramValue;
}
else if (url.indexOf(paramName + "=") >= 0)
{
var decode = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); };
var keyValues = queryString.split('&');
for(var i in keyValues) {
var key = keyValues[i].split('=');
if (key.length > 1) {
if(newQueryString.length > 0) {newQueryString += "&";}
if(decode(key[0]) == paramName)
{
newQueryString += key[0] + "=" + encodeURIComponent(paramValue);;
}
else
{
newQueryString += key[0] + "=" + key[1];
}
}
}
}
else
{
if (url.indexOf("?") < 0)
newQueryString = "?" + paramName + "=" + paramValue;
else
newQueryString = queryString + "&" + paramName + "=" + paramValue;
}
window.location.href = window.location.href.split('?')[0] + "?" + newQueryString;
}
i would suggest a little change to #Lajos's answer... in my particular situation i could potentially have a hash as part of the url, which will cause problems for parsing the parameter that we're inserting with this method after the redirect.
function setGetParameter(paramName, paramValue) {
var url = window.location.href.replace(window.location.hash, '');
if (url.indexOf(paramName + "=") >= 0) {
var prefix = url.substring(0, url.indexOf(paramName));
var suffix = url.substring(url.indexOf(paramName));
suffix = suffix.substring(suffix.indexOf("=") + 1);
suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
url = prefix + paramName + "=" + paramValue + suffix;
}else {
if (url.indexOf("?") < 0)
url += "?" + paramName + "=" + paramValue;
else
url += "&" + paramName + "=" + paramValue;
}
url += window.location.hash;
window.location.href = url;
}
This is my sample code for rebuild url query string with JS
//function get current parameters
$.urlParam = function(name){
var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
if (results==null){
return null;
}
else{
return results[1] || 0;
}
};
//build a new parameters
var param1 = $.urlParam('param1');
var param2 = $.urlParam('param2');
//check and create an array to save parameters
var params = {};
if (param1 != null) {
params['param1'] = param1;
}
if (order != null) {
params['param2'] = param2;
}
//build a new url with new parameters using jQuery param
window.location.href = window.location.origin + window.location.pathname + '?' + $.param(params);
I used JQUERY param: http://api.jquery.com/jquery.param/ to create a new url with new parameters.
I need help to adjust my script below or to find a script that could be used on my wordpress site to grab the url suffix parameters from a forward url, then to be added at the button click url for tracking the proper forward ads id.
REASON: parameters are used for advertisement tracking to find out from which ad the user has been forward, even if the user hops from optin page to the sales page by using button click.
Here the goal to reach:
1. An FB ad points to an optin page with tracking code: https://ownsite.com/optin-page/?tid=fbad1
2. At the optin-page there is a button with a setup URL to forward to the sales page, but if clicked then only the URL is forward, but the parameter "?tid=fbad1" is missing.
3. The auto-forward script below (which is working properly) can be used to change for button click forward, but has a limitation as it grab only "tid" parameters instead also utm parameters.
Therefore a script code shall be implemented to establish click buttons (also to style them or use images instead) and while clicking the button to forward to a different sales page with grabbing the suffix parameter form the current optin-page to forward then to sales-page https://ownsite.com/sales-page/?tid=fbad1 also including UTM parameters
Currently, I could have solved this by using an auto-redirect script, but
A.) I do not want to use an autoredirect at this page. Better is an event click button used to let the user himself click to forward with the URL parameter included.
B.) The tracking ID parameter in this script is limited to "?tid=..." instead I do also want to track the UTM code on button click also
i.e. Grab from current page the paramater of URL https://www.optin-page.com/?tid=facebookad1?utm_campaign=blogpost then on button click grab parameters and add to button set URL https://www.sales-page.com/?tid=facebookad1?utm_campaign=blogpost
Please now find here the Code below in use for auto-redirect and grabbing the URL parameters. This code shall be changed now to be able to create a button with a click-event to be redirect then to the forward URL with parameter grabbing of current URL if the button is clicked (as stated above).

}
