对象的深度克隆

1.使用typeof区分基本数据类型和引用数据类型 

2.使用Object.prototype.toString.call()来区分array和object

具体实现代码：

function deepclone(origin,target){
			var obj_value = "[objcet objcet]";
			toStr = Object.prototype.toString;
			for(var prop in origin){
				if(origin.hasOwnProperty(prop)){
					if(typeof origin[prop] =="object"){
						if(toStr.call(origin[prop],null)==obj_value){
							target[prop]={}
						}else{
							target[prop]=[];
						}
					deepclone(origin[prop],target[prop]);
					}else{
						target[prop]=origin[prop];
					}
				}
			}
			return target;
		}

		var obj ={
			name:"chen",
			age:23,
			skill:["132",456,3543],
			habbits:{
				name:"dsjak",
				age:"0"
			}
		}
		var obj1 = {};
		deepclone(obj,obj1);
