B数组：原始数据跟以下格式一样

    "data": [{
        "areaId": 116,
        "sceneryLevel": "其他",
        "longitude": 115.9958630000000,
        "latitude": 23.5810580000000,
        "areaName": "黄满磜瀑布群",
        "parentAreaId": 144,
        "subscriberCount": 1329,
        "rank": 1
    }, {
        "areaId": 120,
        "sceneryLevel": "其他",
        "longitude": 115.9019510000000,
        "latitude": 23.4959750000000,
        "areaName": "龙潭镇关山村",
        "parentAreaId": 144,
        "subscriberCount": 582,
        "rank": 2
    }, {
        "areaId": 119,
        "sceneryLevel": "其他",
        "longitude": 115.8277720000000,
        "latitude": 23.4210060000000,
        "areaName": "河婆街道三山国王祖庙",
        "parentAreaId": 144,
        "subscriberCount": 515,
        "rank": 3
    }, {
        "areaId": 112,
        "sceneryLevel": "4A",
        "longitude": 115.9968790000000,
        "latitude": 23.5813220000000,
        "areaName": "黄满寨瀑布旅游区",
        "parentAreaId": 144,
        "subscriberCount": 467,
        "rank": 4
    }, {
        "areaId": 115,
        "sceneryLevel": "其他",
        "longitude": 115.9332120000000,
        "latitude": 23.5521900000000,
        "areaName": "大北山森林公园",
        "parentAreaId": 144,
        "subscriberCount": 393,
        "rank": 5
    }]

方法一：

  let C = [];

      B.map(v => {

        if (this.A.indexOf(v['areaName']) <= -1) {

          hideList.push(v)

        }
      })

 方法二：

B.filter(item=> A.indexOf(item.openId) > -1);
