javascript read query parameters
// example url: https://mydomain.com/?fname=johnny&lname=depp
const queryString = window.location.search;
console.log(queryString);
// ?fname=johnny&lname=depp
const urlParams = new URLSearchParams(queryString);
const firstName = urlParams.get('fname');
console.log(firstName);
// johnny
const lastName = urlParams.get('lname');
console.log(lastName);
// deppjs get query param
const queryString = window.location.search;
const parameters = new URLSearchParams(queryString);
const value = parameters.get('key');get query param javascript
const urlParams = new URLSearchParams(window.location.search);
const myParam = urlParams.get('myParam');javascript get query parameter
function getUrlParameter(name) {
name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');
var regex = new RegExp('[\\?&]' + name + '=([^&#]*)');
var results = regex.exec(location.search);
return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' '));
};javascript get params from query strinG
let parameters = 'www.goole.com?code=1232';
// const value = parameters.get('emailVf');
var search = parameters.split('?')[1];
parameters = JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')
alert(JSON.stringify(parameters))
output : {code:1232}:
)=================================================
IF YOU WANT TO USE URL FROM BROWSER THEN USE
==========================
const parameters = window.location.search;
var search = parameters.split('?')[1];
parameters = JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')
alert(JSON.stringify(parameters))
___________________________________________
ANOTHER WAY IS ======================[[
const queryString = window.location.search;
const parameters = new URLSearchParams(queryString);
const value = parameters.get('key');query params
constructor(private router: Router) { }
public myMethodChangingQueryParams() {
const queryParams: Params = { myParam: 'myNewValue' };
this.router.navigate(
[],
{
relativeTo: activatedRoute,
queryParams: queryParams,
queryParamsHandling: 'merge', // remove to replace all query params by provided
});
