操纵对象的javascript

Question

我有一个物体看起来像这样

{
   "A": [ "1", "2", "3" ]
}  

我想操纵对象以获得以下结果：

{
    "A": [{
        "A": "1"
    }, {
        "A": "2"
    }, {
        "A": "3"
   }]
}

实现这一目标的途径是什么

Answer 1

如果你想知道如何转换

var myObj = {
   "A": [ "1", "2", "3" ]
} // this is the object you want to convert

var newObj = {}; //create a new empty object

newObj.A = [];// set a Key "A" of newObj to an empty Array.

for (i = 0; i < myObj.A.length; i++) //loop through the initial object and convert it
    {

     newobj.A[i] = {"A":myObj.A[i]} //for every iteration, add an object to the empty array.(newObj.A)
};

Answer 2

正如@MelanciaUK所提到的，您必须编写代码。你需要调用的不仅仅是convert方法

以下示例适用于您的用例

var myObj = {
   "A": [ "1", "2", "3" ]
}

//convert it
myObj = {
    "A": [{
        "A": "1"
    }, {
        "A": "2"
    }, {
        "A": "3"
   }]
}

//print result
console.log(myObj);
