const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const code = urlParams.get('code')
Awful Anaconda
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const code = urlParams.get('code')// Example URL: https://example.com/over/there?name=ferret
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const parameter_name = urlParams.get('name')
console.log(parameter_name);let url = 'https://www.example.com?name=n1&name=n2';
let params = (new URL(url)).searchParams;
params.get('name') // "n1"
params.getAll('name') // ["n1", "n2"]const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const page_type = urlParams.get('page_type')
console.log(page_type);var url_string = "http://www.example.com/t.html?a=1&b=3&c=m2-m3-m4-m5"; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("c");
console.log(c);www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5
