Javascript 过滤嵌套的JSON数据,javascript,json,javascript-objects,Javascript,Json,Javascript Objects,首先，让我解释一下我想要实现的目标 我希望获取从API接收的数据，并根据某个值对其进行过滤。我将在下面发布JSON { assetNo: { type: 'string', format: 'short-text', minLength: 0, maxLength: 100, description: 'Asset ID' }, serialNo: { type: 'string', format: 'short-text', minLength: 0, maxLength:

首先，让我解释一下我想要实现的目标

我希望获取从API接收的数据，并根据某个值对其进行过滤。我将在下面发布JSON

{ assetNo:
{ type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'Asset ID' },
 serialNo:
 { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'Serial Number' },
 'item:model':
 { type: 'object',
 properties: { title: [Object], _id: [Object] },
 description: 'Model' },
 'location:location':
 { type: 'object',
 properties: { title: [Object], _id: [Object] },
 description: 'Location ID' },
 'item:status':
 { type: 'object',
 properties: { title: [Object], _id: [Object] },
 description: 'Status' },
 imei:
 { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'IMEI' },
 hostName:
 { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'Host Name' },
 staticIp:
 { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'Static IP' },
 mac:
  { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'MAC' },
 macFriendlyName:
 { type: 'string',
 format: 'short-text',
 minLength: 0,
 maxLength: 100,
 description: 'MAC Friendly Name' },
 manufacturerWarrantyEndDate:
 { type: 'string',
 format: 'date-time',
 description: 'Manufacturer Warranty End Date' },
 notes:
 { type: 'string',
 format: 'long-text',
 minLength: 0,
 maxLength: 100,
 description: 'Notes' },
 _id:
 { type: 'string',
 format: 'BSON ObjectID',
 example: '12344ac4ac34d504212c0db6' } }
如您所见，有几个嵌套对象。。。平展下来，数据看起来像这样

我如何遍历这些数据，展平嵌套对象，并仅返回“type”的key/val

例如。。。我想退回这样的东西

您必须使用递归函数，因为您不知道对象的嵌套方式。查看此函数

const mapObj = (data) => {
    return Object.keys(data).reduce((agg, ele) => {
        if (ele === 'type') {
            agg.type = data[ele];
        } else if (typeof data[ele] === 'object') {
            agg[ele] = mapObj(data[ele]);
        }
        return agg;
    }, new Object());
};
用JSON调用此函数，它会起作用。
