url參數轉對象

let url="http://www.aaa.com?id=zhangsan&name=%E5%BC%A0%E4%B8%89&age=35&%E5%BC%A0%E4%B8%89=666";
function queryString2Obj(url){
	let str=url.split("?")[1];
	let items=str.split("&");
	let result={}
	let arr=[];
	for(let i=0; i<items.length; i++){
		arr=items[i].split('=');
		result[decodeURIComponent(arr[0])]=decodeURIComponent(arr[1]);
	}
	
	return result;
}

let obj=queryString2Obj(url);
console.log(obj)

{id: "zhangsan", name: "張三", age: "35", 張三: "666"}
