arrays - 将嵌套对象推送到数组

Question

如何将嵌套的 json 对象插入数组。这是示例 json 对象。假设我有 100 个 GROUP。

data="result": {
    "GROUP_A": {
        "statistics": {
            "year2000": 8666,
            "year2001": 1213,
            "year2002": 123,
        },
        "trending": {
            "year2000": 90,
            "year2001": 78,
            "year2002": 86,
        }
    }
    "GROUP_B": {
        "statistics": {
            "year2000": 43223,
            "year2001": 4234,
            "year2002": 124343,
        },
        "trending": {
            "year2000": 34,
            "year2001": 43,
            "year2002": 45,
        }
    }
}

示例输出如下:

"result": [{
    "GROUP_A": [{
        "statistics": {
            "year2000": 8666,
            "year2001": 1213,
            "year2002": 123,
        },
        "trending": {
            "year2000": 90,
            "year2001": 78,
            "year2002": 86,
        }
    }]
    "GROUP_B": [{
        "statistics": {
            "year2000": 43223,
            "year2001": 4234,
            "year2002": 124343,
        },
        "trending": {
            "year2000": 34,
            "year2001": 43,
            "year2002": 45,
        }
    }]
}] 

我不知道该怎么做。如果是简单的对象，我可以这样推送:

var arr=[];

arr.push(数据);

之所以插入数组，是因为组的键对象是动态的。我想使用组来过滤数据。

Answer 1

我用两种不同的方式做到了这一点:

1. 创建一个对象数组，这很常见

   var array = [];
   
   // ARRAY OF OBJECTS
   for(i in data) {
       // Create new array above and push every object in
       array.push(data[i]);
   }
   console.log(JSON.stringify(array));
   

2. 你想要的方式(有数组的对象有数组有对象)

   // OBJECT OF ARRAYS OF ARRAYS
   var result = data["result"];
   // Create head of object, "result"
   var obj = {"result":[]};
   var smallObj = {};
   // Push objects inside array
   for(i in result) {
       var smallArray = [];
       smallArray.push(result[i]);
       // Store that array onto array og objects, which in this case is array of arrays of objects
       smallObj[i] = smallArray;
   }
   // Final result
   obj["result"].push(smallObj);
   console.log(JSON.stringify(obj));
   

这是 JSFiddle，因此您可以在控制台中看到打印的字符串化版本:https://jsfiddle.net/0Loh0ucm/
