编写一个JavaScript函数,把URL参数解析为一个对象

 <script>

let url = "http://witmax.cn/index.php?key0=0&key1=1&key2=2";

let hongdou = url.indexOf("?");   //检索

let str = url.slice(hongdou+1);   //选取

let arr = str.split("&");                //分割

let result =[];

let obj = {};

for(let i=0;i<arr.length;i++){

result = arr[i].split("=");         //分割

obj[result[0]] = result[1];

}

console.log(obj);

</script>
