js對象替換鍵值名稱

將obj中的id和name字段替換分別替換成為“@id”，“@name”

代碼如下：

let obj = [{id:1,name:"張三"},{id:2,name:"李四"}].map(function (item) {
    return{
        "@id":item.id,
        "@name":item.name
    }
})

 

對於對象

let obj = {
    id:1,
    name:"張三",
    age:20,
    grade:{
        Math :90,
        English :80
    }
}

例如：替換obj中grade屬性，將Math替換Chinese，將English替換成Chemistry

完整代碼為：

let obj = {
    id:1,
    name:"張三",
    age:20,
    grade:{
        Math :90,
        English :80
    }
}

obj.grade["Chinese"] = obj.grade.Math;
obj.grade["Chemistry"] = obj.grade.English;
delete obj.grade.Math;
delete obj.grade.English;
console.log(obj);       //{ id: 1,name: '張三',age: 20,grade: { Chinese: 90, Chemistry: 80 } }
