将对象数组转换为属性数组 [英] Convert array of objects into array of properties

问题描述

是否有一种简单的方法，使用 filter 或解析或其他内容来转换数组，如下所示：

Is there a simple way, using filter or parse or something else to convert an array like the following :

var someJsonArray = [
  {id: 0, name: "name", property: "value", otherproperties: "othervalues"},
  {id: 1, name: "name1", property: "value1", otherproperties: "othervalues1"},
  {id: 2, name: "name2", property: "value2", otherproperties: "othervalues2"}
];

进入一个简单的数组，其中包含前一个数组中包含的对象的一个​​属性，如下所示：

into a simple array filled with one attribute of the objects contained in the previous array like this :

[0, 1, 2]

推荐答案

使用 .map（） 功能：

finalArray = someJsonArray.map(function (obj) {
  return obj.id;
});

Snippet

var someJsonArray = [
  {id: 0, name: "name", property: "value", therproperties: "othervalues"},
  {id: 1, name: "name1", property: "value1", otherproperties: "othervalues1"},
  {id: 2, name: "name2", property: "value2", otherproperties: "othervalues2"}
];
var finalArray = someJsonArray.map(function (obj) {
  return obj.id;
});
console.log(finalArray);

上面的代码片段已更改为有效。

The above snippet is changed to make it work.
