Question

如何将嵌套的json对象推入数组。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。如果简单的对象，我可以这样推：

var arr=[];

arr.push（数据）;

推入阵列的原因，因为组的关键对象是动态的。我想用group来过滤数据。

我做了两种不同的方式：

创建一个对象数组，这是常见的

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));

您想要的方式（包含数组的数组的对象具有对象）

// 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，因此您可以看到控制台中打印的字符串化版本：https://jsfiddle.net/0Loh0ucm/
