I have this URL:
site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc
what I need is to be able to change the 'rows' url param value to something i specify, lets say 10. And if the 'rows' doesn't exist, I need to add it to the end of the url and add the value i've already specified (10).
To answer my own question 4 years later, after having learned a lot. Especially that you shouldn't use jQuery for everything. I've created a simple module that can parse/stringify a query string. This makes it easy to modify the query string.
You can use query-string as follows:
// parse the query string into an object
var q = queryString.parse(location.search);
// set the `row` property
q.rows = 10;
// convert the object to a query string
// and overwrite the existing query string
location.search = queryString.stringify(q);
I've extended Sujoy's code to make up a function.
/**

*/
function updateURLParameter(url, param, paramVal){
var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];
var additionalURL = tempArray[1];
var temp = "";
if (additionalURL) {
tempArray = additionalURL.split("&");
for (var i=0; i<tempArray.length; i++){
if(tempArray[i].split('=')[0] != param){
newAdditionalURL += temp + tempArray[i];
temp = "&";
}
}
}
var rows_txt = temp + "" + param + "=" + paramVal;

Function Calls:

newURL = updateURLParameter(newURL, 'resId', 'newResId');
window.history.replaceState('', '', updateURLParameter(window.location.href, "param", "value"));
Updated version that also take care of the anchors on the URL.
function updateURLParameter(url, param, paramVal)

var TheAnchor = null;
var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];

http://www.domain.com/index.php?action=my_action&view-all=Yes and I need to change the "view-all" value. My SO question that was closed: #13026380 –
Euphonize paramVal === null. For this effect I've replaced the last 2 lines to the following: if ( paramVal !== null ) newAdditionalURL += temp + '' + param + '=' + paramVal; return baseURL + '?' + newAdditionalURL; –
Heuristic "" onto a string: var rows_txt = temp + "" + param + "=" + paramVal; –
Pedo param and paramVal. It's not safe to use if user input can affect either parameter. –
Lehrer I think you want the query plugin.
E.g.:
window.location.search = jQuery.query.set("rows", 10);
This will work regardless of the current state of rows.
window.location.pathname. –
Calciferous jQuery.query.load to get a query object. Demo. –
Calciferous Quick little solution in pure js, no plugins needed:
function replaceQueryParam(param, newval, search) {
var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
var query = search.replace(regex, "$1").replace(/&$/, '');
return (query.length > 2 ? query + "&" : "?") + (newval ? param + "=" + newval : '');
}
Call it like this:
window.location = '/mypage' + replaceQueryParam('rows', 55, window.location.search)
Or, if you want to stay on the same page and replace multiple params:
var str = window.location.search
str = replaceQueryParam('rows', 55, str)
str = replaceQueryParam('cols', 'no', str)
window.location = window.location.pathname + str
edit, thanks Luke: To remove the parameter entirely, pass false or null for the value: replaceQueryParam('rows', false, params). Since 0 is also falsy, specify '0'.
To answer my own question 4 years later, after having learned a lot. Especially that you shouldn't use jQuery for everything. I've created a simple module that can parse/stringify a query string. This makes it easy to modify the query string.

A modern approach to this is to use native standard based URLSearchParams. It's supported by all major browsers, except for IE where polyfills are available.
const paramsString = "site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc"
const searchParams = new URLSearchParams(paramsString);
searchParams.set('rows', 10);
console.log(searchParams.toString()); // return modified string.
site.fwx%3Fposition=1&archiveid=5000&columns=5&rows=10&sorting=ModifiedTimeAsc which is confusing because it's not what you would have built if you did it manually... –
Fealty new URLSearchParams("site.fwx?position=1&... should be new URLSearchParams("position=1&... (it only takes the search string, not a path as well). I'd edited to fix but the edit is being rejected? Also @the-godfather const searchParams = new URLSearchParams(location.search); searchParams.set('rows', 10); location.search = searchParams; is the extra info you wanted in this answer. –
Listel searchParams.get('param'). Works in Node. –
Dorcy Ben Alman has a good jquery querystring/url plugin here that allows you to manipulate the querystring easily.
As requested -
Goto his test page here
In firebug enter the following into the console
jQuery.param.querystring(window.location.href, 'a=3&newValue=100');
It will return you the following amended url string
http://benalman.com/code/test/js-jquery-url-querystring.html?a=3&b=Y&c=Z&newValue=100#n=1&o=2&p=3
Notice the a querystring value for a has changed from X to 3 and it has added the new value.
You can then use the new url string however you wish e.g using document.location = newUrl or change an anchor link etc
TypeError: jQuery.param.querystring is not a function –
Peridotite jQuery.param.querystring. I guess they have refactored the library. –
Potvaliant This is the modern way to change URL parameters:
function setGetParam(key,value) {
if (history.pushState) {
var params = new URLSearchParams(window.location.search);
params.set(key, value);
var newUrl = window.location.origin
+ window.location.pathname
+ '?' + params.toString();
window.history.pushState({path:newUrl},'',newUrl);
}
}
document.title for history title –
Tactless window.location.protocol + "//" + window.location.host + window.location.pathname simply with window.location.origin –
Astrict you can do it via normal JS also
var url = document.URL
var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];
var aditionalURL = tempArray[1];
var temp = "";
if(aditionalURL)
{
var tempArray = aditionalURL.split("&");
for ( var i in tempArray ){
if(tempArray[i].indexOf("rows") == -1){
newAdditionalURL += temp+tempArray[i];
temp = "&";
}
}
}
var rows_txt = temp+"rows=10";
var finalURL = baseURL+"?"+newAdditionalURL+rows_txt;
Use URLSearchParams to check, get and set the parameters value into URL
Here is the example to get the current URL set new parameters and update the URL or reload the page as per your needs
var rows = 5; // value that you want to set
var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));
url.search = url.searchParams;
url = url.toString();
// if you want to append into URL without reloading the page
history.pushState({}, null, url);
// want to reload the window with a new param
window.location = url;
2020 Solution: sets the variable or removes iti if you pass null or undefined to the value.
var setSearchParam = function(key, value) {
if (!window.history.pushState) {
return;
}
if (!key) {
return;
}
var url = new URL(window.location.href);
var params = new window.URLSearchParams(window.location.search);
if (value === undefined || value === null) {
params.delete(key);
} else {
params.set(key, value);
}
url.search = params;
url = url.toString();
window.history.replaceState({url: url}, null, url);
}
URLSearchParams does not work in the latest versions of all major browsers (2020) –
Babbage pushState? Is it to check if this is supported? –
Yaakov Would a viable alternative to String manipulation be to set up an html form and just modify the value of the rows element?
So, with html that is something like
<form id='myForm' target='site.fwx'>
<input type='hidden' name='position' value='1'/>
<input type='hidden' name='archiveid' value='5000'/>
<input type='hidden' name='columns' value='5'/>
<input type='hidden' name='rows' value='20'/>
<input type='hidden' name='sorting' value='ModifiedTimeAsc'/>
</form>
With the following JavaScript to submit the form
var myForm = document.getElementById('myForm');
myForm.rows.value = yourNewValue;
myForm.submit();
Probably not suitable for all situations, but might be nicer than parsing the URL string.
URL query parameters can be easily modified using URLSearchParams and History interfaces:
// Construct URLSearchParams object instance from current URL querystring.
var queryParams = new URLSearchParams(window.location.search);
// Set new or modify existing parameter value.
//queryParams.set("myParam", "myValue");
queryParams.set("rows", "10");
// Replace current querystring with the new one.
history.replaceState(null, null, "?"+queryParams.toString());
Alternatively instead of modifying current history entry using replaceState() we can use pushState() method to create a new one:
history.pushState(null, null, "?"+queryParams.toString());
https://zgadzaj.com/development/javascript/how-to-change-url-query-parameter-with-javascript-only
You can use this my library to do the job: https://github.com/Mikhus/jsurl
var url = new Url('site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc');
url.query.rows = 10;
alert( url);
Consider this one:
const myUrl = new URL("http://www.example.com?columns=5&rows=20");
myUrl.searchParams.set('rows', 10);
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10
myUrl.searchParams.set('foo', 'bar'); // add new param
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10&foo=bar
It will do exactly the same thing you required. Please note URL must have correct format. In your example you have to specify protocol (either http or https)
I wrote a little helper function that works with any select. All you need to do is add the class "redirectOnChange" to any select element, and this will cause the page to reload with a new/changed querystring parameter, equal to the id and value of the select, e.g:
<select id="myValue" class="redirectOnChange">
<option value="222">test222</option>
<option value="333">test333</option>
</select>
The above example would add "?myValue=222" or "?myValue=333" (or using "&" if other params exist), and reload the page.
jQuery:
$(document).ready(function () {
//Redirect on Change
$(".redirectOnChange").change(function () {
var href = window.location.href.substring(0, window.location.href.indexOf('?'));
var qs = window.location.href.substring(window.location.href.indexOf('?') + 1, window.location.href.length);
var newParam = $(this).attr("id") + '=' + $(this).val();
if (qs.indexOf($(this).attr("id") + '=') == -1) {
if (qs == '') {
qs = '?'
}
else {
qs = qs + '&'
}
qs = qs + newParam;
}
else {
var start = qs.indexOf($(this).attr("id") + "=");
var end = qs.indexOf("&", start);
if (end == -1) {
end = qs.length;
}
var curParam = qs.substring(start, end);
qs = qs.replace(curParam, newParam);
}
window.location.replace(href + '?' + qs);
});
});
Using javascript URL:
var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));
window.location = url;
var url = new URL(window.location.href);
var search_params = url.searchParams;
search_params.set("param", value);
url.search = search_params.toString();
var new_url = url.pathname + url.search;
window.history.replaceState({}, '', new_url);
In the URLSearchParams documentation, there's a very clean way of doing this, without affecting the history stack.
// URL: https://example.com?version=1.0
const params = new URLSearchParams(location.search);
params.set('version', 2.0);
window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?version=2.0
Similarily, to remove a parameter
params.delete('version')
window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?
Here I have taken Adil Malik's answer and fixed the 3 issues I identified with it.
/**
* Adds or updates a URL parameter.

self.setParameter = function (url, param, paramVal){
// https://mcmap.net/q/75486/-change-url-parameters-and-specify-defaults-using-javascript
var parts = url.split('?');
var baseUrl = parts[0];
var oldQueryString = parts[1];
var newParameters = [];
if (oldQueryString) {
var oldParameters = oldQueryString.split('&');
for (var i = 0; i < oldParameters.length; i++) {
if(oldParameters[i].split('=')[0] != param) {
newParameters.push(oldParameters[i]);
}
}
}
if (paramVal !== '' && paramVal !== null && typeof paramVal !== 'undefined') {
newParameters.push(param + '=' + encodeURI(paramVal));
}
if (newParameters.length > 0) {
return baseUrl + '?' + newParameters.join('&');
} else {
return baseUrl;
}
}
let url= new URL("https://example.com/site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc")
url.searchParams.set('rows', 10)
console.log(url.toString())Here is what I do. Using my editParams() function, you can add, remove, or change any parameter, then use the built in replaceState() function to update the URL:
window.history.replaceState('object or string', 'Title', 'page.html' + editParams('sorting', ModifiedTimeAsc));
// background functions below:
// add/change/remove URL parameter
// use a value of false to remove parameter
// returns a url-style string
function editParams (key, value) {
key = encodeURI(key);
var params = getSearchParameters();
if (Object.keys(params).length === 0) {
if (value !== false)
return '?' + key + '=' + encodeURI(value);
else
return '';
}
if (value !== false)
params[key] = encodeURI(value);
else
delete params[key];
if (Object.keys(params).length === 0)
return '';
return '?' + $.map(params, function (value, key) {
return key + '=' + value;
}).join('&');
}
// Get object/associative array of URL parameters
function getSearchParameters () {
var prmstr = window.location.search.substr(1);
return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}
// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
var params = {},
prmarr = prmstr.split("&");
for (var i = 0; i < prmarr.length; i++) {
var tmparr = prmarr[i].split("=");
params[tmparr[0]] = tmparr[1];
}
return params;
}
My solution:
const setParams = (data) => {
if (typeof data !== 'undefined' && typeof data !== 'object') {
return
}
let url = new URL(window.location.href)
const params = new URLSearchParams(url.search)
for (const key of Object.keys(data)) {
if (data[key] == 0) {
params.delete(key)
} else {
params.set(key, data[key])
}
}
url.search = params
url = url.toString()
window.history.replaceState({ url: url }, null, url)
}
Then just call "setParams" and pass an object with data you want to set.
Example:
$('select').on('change', e => {
const $this = $(e.currentTarget)
setParams({ $this.attr('name'): $this.val() })
})
In my case I had to update a html select input when it changes and if the value is "0", remove the parameter. You can edit the function and remove the parameter from the url if the object key is "null" as well.
Hope this helps yall
If you want to change the url in address bar:
const search = new URLSearchParams(location.search);
search.set('rows', 10);
location.search = search.toString();
Note, changing location.search reloads the page.
Here is a simple solution using the query-string library.
const qs = require('query-string')
function addQuery(key, value) {
const q = qs.parse(location.search)
const url = qs.stringifyUrl(
{
url: location.pathname,
query: {
...q,
[key]: value,
},
},
{ skipEmptyString: true }
);
window.location.href = url
// if you are using Turbolinks
// add this: Turbolinks.visit(url)
}
// Usage
addQuery('page', 2)
If you are using react without react-router
export function useAddQuery() {
const location = window.location;
const addQuery = useCallback(
(key, value) => {
const q = qs.parse(location.search);
const url = qs.stringifyUrl(
{
url: location.pathname,
query: {
...q,
[key]: value,
},
},
{ skipEmptyString: true }
);
window.location.href = url
},
[location]
);
return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)
If you are using react with react-router
export function useAddQuery() {
const location = useLocation();
const history = useHistory();
const addQuery = useCallback(
(key, value) => {
let pathname = location.pathname;
let searchParams = new URLSearchParams(location.search);
searchParams.set(key, value);
history.push({
pathname: pathname,
search: searchParams.toString()
});
},
[location, history]
);
return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)
PS: qs is the import from query-string module.
Another variation on Sujoy's answer. Just changed the variable names & added a namespace wrapper:
window.MyNamespace = window.MyNamespace || {};
window.MyNamespace.Uri = window.MyNamespace.Uri || {};
(function (ns) {
ns.SetQueryStringParameter = function(url, parameterName, parameterValue) {
var otherQueryStringParameters = "";
var urlParts = url.split("?");
var baseUrl = urlParts[0];
var queryString = urlParts[1];
var itemSeparator = "";
if (queryString) {
var queryStringParts = queryString.split("&");
for (var i = 0; i < queryStringParts.length; i++){
if(queryStringParts[i].split('=')[0] != parameterName){
otherQueryStringParameters += itemSeparator + queryStringParts[i];
itemSeparator = "&";
}
}
}
var newQueryStringParameter = itemSeparator + parameterName + "=" + parameterValue;
return baseUrl + "?" + otherQueryStringParameters + newQueryStringParameter;
};
})(window.MyNamespace.Uri);
Useage is now:
var changedUrl = MyNamespace.Uri.SetQueryStringParameter(originalUrl, "CarType", "Ford");
I too have written a library for getting and setting URL query parameters in JavaScript.
Here is an example of its usage.
var url = Qurl.create()
, query
, foo
;
Get query params as an object, by key, or add/change/remove.
// returns { foo: 'bar', baz: 'qux' } for ?foo=bar&baz=qux
query = url.query();
// get the current value of foo
foo = url.query('foo');
// set ?foo=bar&baz=qux
url.query('foo', 'bar');
url.query('baz', 'qux');
// unset foo, leaving ?baz=qux
url.query('foo', false); // unsets foo
I was looking for the same thing and found: https://github.com/medialize/URI.js which is quite nice :)
-- Update
I found a better package: https://www.npmjs.org/package/qs it also deals with arrays in get params.
No library, using URL() WebAPI (https://developer.mozilla.org/en-US/docs/Web/API/URL)
function setURLParameter(url, parameter, value) {
let url = new URL(url);
if (url.searchParams.get(parameter) === value) {
return url;
}
url.searchParams.set(parameter, value);
return url.href;
}
This doesn't work on IE: https://developer.mozilla.org/en-US/docs/Web/API/URL#Browser_compatibility
I know this is an old question. I have enhanced the function above to add or update query params. Still a pure JS solution only.
function addOrUpdateQueryParam(param, newval, search) {
var questionIndex = search.indexOf('?');
if (questionIndex < 0) {
search = search + '?';
search = search + param + '=' + newval;
return search;
}
var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
var query = search.replace(regex, "$1").replace(/&$/, '');
var indexOfEquals = query.indexOf('=');
return (indexOfEquals >= 0 ? query + '&' : query + '') + (newval ? param + '=' + newval : '');
}
my function support removing param
function updateURLParameter(url, param, paramVal, remove = false) {
var newAdditionalURL = '';
var tempArray = url.split('?');
var baseURL = tempArray[0];
var additionalURL = tempArray[1];
var rows_txt = '';
if (additionalURL)
newAdditionalURL = decodeURI(additionalURL) + '&';
if (remove)
newAdditionalURL = newAdditionalURL.replace(param + '=' + paramVal, '');
else
rows_txt = param + '=' + paramVal;
window.history.replaceState('', '', (baseURL + "?" + newAdditionalURL + rows_txt).replace('?&', '?').replace('&&', '&').replace(/\&$/, ''));
}
I just wrote a simple module to deal with reading and updating the current url query params.
Example usage:
import UrlParams from './UrlParams'
UrlParams.remove('foo') //removes all occurences of foo=?
UrlParams.set('foo', 'bar') //set all occurences of foo equal to bar
UrlParams.add('foo', 'bar2') //add bar2 to foo result: foo=bar&foo=bar2
UrlParams.get('foo') //returns bar
UrlParams.get('foo', true) //returns [bar, bar2]
