想取得網頁傳遞參數可透過JavaScript的方法解析網址geturlparameter
目標從 http://localhost/geturlparameter.html?id=21&name=Tom
var getUrlString = location.href;
url.searchParams.get('id'); // 回傳 21
url.searchParams.get('name'); //回傳 Tom
或是
let params = (new URL(document.location)).searchParams;
let name = params.get('id'); // 21.
let age = parseInt(params.get('name')); // Tom
