JavaScript如何深度克隆函数对象！

JavaScript如何深度克隆函数对象 在js中函数是对象有属性 但是要怎样做才能让函数对象拷贝出一个完整的副本

//深度克隆
function deepClone(obj){
var result,oClass=isClass(obj);
//确定result的类型
if(oClass==="Object"){
result={};
}else if(oClass==="Array"){
result=[];
}else{
return obj;
}
for(key in obj){
var copy=obj[key];
if(isClass(copy)=="Object"){
result[key]=arguments.callee(copy);//递归调用
}else if(isClass(copy)=="Array"){
result[key]=arguments.callee(copy);
}else{
result[key]=obj[key];
}
}
return result;
}
//返回传递给他的任意对象的类
function isClass(o){
if(o===null) return "Null";
if(o===undefined) return "Undefined";
return Object.prototype.toString.call(o).slice(8,-1);
}
var oPerson={
oName:"rookiebob",
oAge:"18",
oAddress:{
province:"beijing"
},

ofavorite:[
"swimming",
{reading:"history book"}
],
skill:function(){
console.log("bob is coding");
}
};
//深度克隆一个对象
var oNew=deepClone(oPerson);

oNew.ofavorite[1].reading="picture";
console.log(oNew.ofavorite[1].reading);//picture
console.log(oPerson.ofavorite[1].reading);//history book

oNew.oAddress.province="shanghai";
console.log(oPerson.oAddress.province);//beijing
console.log(oNew.oAddress.province);//shanghai
