1、路由跳转方式：域名?参数名=值&参数名=值
2、获取参数：
	let url = window.location.href;
	let option,strs;
	if (url) {
		if (url.indexOf("?") != -1) {
			let str = url.substr(0);
			strs = str.split("&");
			for (let i = 0;i < strs.length;i++) {
				param = (strs[i].split("="))[0];
				option = (strs[i].split("="))[1];// 拿到的参数
			}
		}
		option = decodeURI(option);//解码
	}
