javascript - 将javascript关联数组转换为多对象数组

Question

这是我的输入:

输入可能会收到更多数据，如 'e:5'

  var input = {a:2,b:3,c:2,d:1};

我想将此输入转换为以下输出:

var output = [{name="a",id="2"},
              {name="b",id="3"},
              {name="c",id="2"},
              {name="d",id="1"}];

提前致谢。

使用Array#map在 Object.keys

The Object.keys() method returns an array of a given object's own enumerable properties.

---

The map() method creates a new array with the results of calling a provided function on every element in this array.

---

var input = {
  a: 2,
  b: 3,
  c: 2,
  d: 1
};

var mapped = Object.keys(input).map(function(key) {
  return {
    name: key,
    id: input[key]
  };
});
console.log(mapped);
