编写一个函数实现对Object，Array，Boolean，Number，String这五种主要数据类型进行值复制。
网上搜到的参考解答：Object，Array，Boolean，Number，String分为三种情况：普通变量，Array，Object ，使用递归调用方式解题-->
<h1 id="arra"></h1>
<h1 id="obj"></h1>
<h1 id="num"></h1>
<script>
function clone(Obj){
var buf;
if(Obj instanceof Array){
buf = []; //创建一个空数组
var i = Obj.length;
while(i--){
buf[i] = clone(Obj[i]);
}
return buf;
}
else if (Obj instanceof Object) {
buf = {}; //创建一个空对象
for(var k in Obj){
buf[k] = clone(Obj[k]);
}
return buf;
}
else {
return Obj; //普通对象直接赋值
}
}
var data = clone([1,2,3,4,5,'fff']);
document.getElementById("arra").innerHTML = data;
console.log(data);
var data1 = clone({'id':1,'name':'lily'});
