js获取url地址？后面参数

let url = window.location.search;

var theRequest = new Object();

if (url.indexOf("?") != -1) {

var str = url.substr(1);

strs = str.split("&");

for (var i = 0; i < strs.length; i++) {

theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);

}

}

console.log(theRequest)
