将数据格式从单个对象转换为键值对的对象数组

Question

I have a data in a single object as json-format:

var a = {
    "1": "alpha",
    "2": "beta",
    "3": "ceta"
}

I want to convert it into the following format:

var b = [
    {id: 1, label: "alpha"},
    {id: 2, label: "beta"},
    {id: 3, label: "ceta"}
];

Can someone suggest a way to do this?

Answer 1

You can try following

 var a = { "1": "alpha", "2": "beta", "3": "ceta" } var b = []; for (var key in a) { if (a.hasOwnProperty(key)) { b.push({ "id": key, "label": a[key] }); } } console.dir(b); 

Please note - You need to update your object a - Commas are missing

Answer 2

This proposal features Object.keys() and Array#map() .

 var a = { "1": "alpha", "2": "beta", "3": "ceta" }, b = Object.keys(a).map(function (k) { return { id: k, label: a[k] }; }); document.write('<pre>' + JSON.stringify(b, 0, 4) + '</pre>'); 

Answer 3

try

var b = [];

for ( var key in a )
{
   b.push( { id : key, label :a[key] } );
}
console.log(b);
