JavaScript获取地址栏参数的方法实现

//获取地址栏参数，key:参数名称
function getUrlParams(key) {
	let reg = new RegExp("(^|&)" + key + "=([^&]*)(&|$)");
	let r = window.location.search.substr(1)
		.match(reg);
	if (r != null)
		return unescape(r[2]);
	return null;
}
let title = getUrlParams("title"); // abc
let type = getUrlParams("type"); // 12

//获取地址栏参数
function getUrlParams() {
	let url = window.location.search; //获取url中"?"符后的字串
	let paramsObj = new Object();
	if (url.indexOf("?") != -1) {
		let str = url.substr(1);
		strs = str.split("&");
		for (let i = 0; i < strs.length; i++) {
			paramsObj[strs[i].split("=")[0]] = decodeURI(strs[i].split("=")[1]);
		}
	}
	return paramsObj;
}
let type = getUrlParams().type; // 12
let title = getUrlParams().title; // abc
