Question

我想用新密钥将数组的结构更改为对象（名称：＆＃34;树＆＃34;）

const myArray = [{"my color": "orange color", "my value":1},{"my color": "red color", "my value":2},etc];

const myObject = {name: "tree",myArray: [{"my color": "orange color", "my value":1},{"my color": "red color", "my value":2},etc]};

此功能效果不佳：

  const k = Object.keys;
  const myObject = k(myArray).map((k) => ({ name: "tree",  myArray: myArray[k] }))

Answer 1

你的回答

const myArray = [{ "my color": "orange color", "my value": 1 }, { "my color": "red color", "my value": 2 }, etc];
    var myObject = new Object();
    myObject.name = "tree";
    myObject.myArray = myArray;
    console.log(myObject);

Answer 2

const myArray = [{"my color": "orange color", "my value":1},{"my color": "red color", "my value":2},etc];
const myObject = { name: "tree", myArray: myArray }

这应该可以解决问题。无需循环任何事情。

如果您需要对象的副本而不是引用，则可以使用spread operator这是一项新的JavaScript功能，旧的浏览器不支持它。

const myArray = [{"my color": "orange color", "my value":1},{"my color": "red color", "my value":2},etc];
const myObject = { name: "tree", myArray: [ ...myArray ] }
