利用stringify()方法，return underfined;可以過(guò)濾key為name的鍵，但是一下過(guò)濾了所有key為name的鍵，怎么控制只過(guò)濾company對(duì)象下面的name呢？

var person = {
            name: "張三",
            age: 14,
            sex: "男",
            tell: 5033453,
            birthday:new Date(),
            company:{
                name:"百度",
                contry:"中國(guó)",
                boss:"馬化騰",
                state:1
            }
        };

        var jperson = JSON.stringify(person,function(key,value){
            switch (key) {
                case "name":
                    return undefined;
                case "state":
                    return value===1?"通過(guò)":"未通過(guò)";
                case "birthday":
                    return value.replace("T"," ").replace("Z","").substr(0,19);
                default:
                    return value;
            }

        });
        console.log(jperson);

結(jié)果：{"age":14,"sex":"男","tell":5033453,"birthday":"2016-05-10 10:48:54","company":{"contry":"中國(guó)","boss":"馬化騰","state":"通過(guò)"}}
