经过多年的丑陋字符串解析之后，有一种更好的方法： URLSearchParams 让我们看看如何使用这个新的API从该位置获取值！

//假设“？post = 1234＆action = edit”

var urlParams = new URLSearchParams(window.location.search);console.log(urlParams.has('post')); // trueconsole.log(urlParams.get('action')); // "edit"console.log(urlParams.getAll('action')); // ["edit"]console.log(urlParams.toString()); // "?post=1234&action=edit"console.log(urlParams.append('active', '1')); // "?post=1234&action=edit&active=1"

更新：不支持IE

使用此函数代替 URLSearchParams

$.urlParam = function (name) {    var results = new RegExp('[?&]' + name + '=([^&#]*)').exec(window.location.href);    if (results == null) {         return 0;    }    return results[1] || 0;}console.log($.urlParam('action')); //edit
