Javascript：将对象的对象转换为对象数组 [英] Javascript: Converting Object of Objects to Array of Objects

问题描述

我正在使用Polymer 1.0进行项目，我想使用 dom-repeat 列出来自Firebase 3.0的数据。

I'm working on a project using Polymer 1.0 and I want to use dom-repeat to list data from Firebase 3.0.

在Firebase中，我有一个像这样的对象：

In Firebase I have an object of objects like this:

var objectofobjects = {
    "-KR1cJhKzg9uPKAplLKd" : {
        "author" : "John J",
        "body" : "vfdvd",
        "time" : "September 6th 2016, 8:11",
        "title" : "vfvfd"
    },
    "-KR1cLZnewbvo45fDnEf" : {
        "author" : "JJ",
        "body" : "vfdvdvf",
        "time" : "September 6th 2016, 8:11",
        "title" : "vfvfdvfdv"
    }
};

我希望将它转换为这样的对象数组：

and I want to convert it to an array of objects like this:

var arrayofobjects = [ { '-KR1cJhKzg9uPKAplLKd': 
 { author: 'John J',
   body: 'vfdvd',
   time: 'September 6th 2016, 8:11',
   title: 'vfvfd' },
'-KR1cLZnewbvo45fDnEf': 
 { author: 'JJ',
   body: 'vfdvdvf',
   time: 'September 6th 2016, 8:11',
   title: 'vfvfdvfdv' } } ];

推荐答案

你可以做到以这种简单的方式：

You can do it in this simple way:

 var arrObj = [];
 var obj = JSON.stringify(objectofobjects, function(key, value) {
     arrObj.push(value);
 })
 console.log(arrObj);

输出将是：

[{
    '-KR1cJhKzg9uPKAplLKd': {
        author: 'John J',
        body: 'vfdvd',
        time: 'September 6th 2016, 8:11',
        title: 'vfvfd'
    },
    '-KR1cLZnewbvo45fDnEf': {
        author: 'JJ',
        body: 'vfdvdvf',
        time: 'September 6th 2016, 8:11',
        title: 'vfvfdvfdv'
    }
}]

注意：您提到的输出不是有效的JSON数组。

Note: The output which you have mentioned is not a valid JSON array.

希望这应该有效。
