編寫一個JavaScript函數,把URL參數解析為一個對象

 <script>

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

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

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

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>
