javascript - 从具有许多记录的 JSON 结果创建 JSON 结构

Question

friend 们，进一步回答我关于Creating JSON structure from JSON results的问题如何创建包含数组中许多 header 的对象？

Here is my Fiddle我的代码如下。

var array = [
    [{
    "label": "NewNetworkServiceProvider",
        "value": "NewNetworkServiceProvidered46c4ee-7ec1-45d6-9d13-94e301d2f890"
}, {
    "label": "PurchaseOrderNumber",
        "value": "PurchaseOrderNumber4be9f460-0c98-4038-910d-027565f83e1c"
}, {
    "label": "RawRecordType",
        "value": "RawRecordType2a774afb-0fd4-4fd4-a3c6-88041de5b1ad"
}],
[{
    "label": "NewNetworkServiceProvider",
        "value": "NewNetworkServiceProvidered46c4ee-7ec1-45d6-9d13-94e301d2f890"
}, {
    "label": "PurchaseOrderNumber",
        "value": "PurchaseOrderNumber4be9f460-0c98-4038-910d-027565f83e1c"
}, {
    "label": "RawRecordType",
        "value": "RawRecordType2a774afb-0fd4-4fd4-a3c6-88041de5m321"
}]
   ];

var obj = {
    header: {}
};
array.forEach(function (item) {
    item.forEach(function (data) {
        obj.header[data.label] = data.value;
    });
});

console.log(obj)

我猜你想要这个:

array.forEach(function (item) {
    item.forEach(function (data) {
        obj.header[data.label] = obj.header[data.label] || [];
        obj.header[data.label].push(data.value);
    });
});
