js 克隆 博客分类： javascript 克隆clone复制对象

js 如何克隆一个对象呢?

var clone = function(src){
            var target = {};
            for(var i in src){
              if(typeof src[i]==='object'){
              target[i] = arguments.callee(src[i]);
                
              }else{
                target[i] = src[i];
              }
            }
            return target;
        }

 测试代码:

var obj2={name:"whuang",age:27,say:function(){console.log("Hello,"+this.name)}};
var obj3={school:"whut"};
obj2.sch=obj3;
var target2=clone(obj2);

console.log(target2.sch.school);
obj2.sch.school="ccc";
console.log(target2.sch.school);
target2.say();

 运行结果:

whut

whut

 

Hello,whuang
