Question

我知道这已经被问过了，但是我似乎找不到答案，我想从isiuser数组中获取no_anggota，nama_lahir和tgl_lahir，我想插入到ZZZ中。

isiseat = [
    [{ x: 0, y: 0, val: 1 },
    { x: 1, y: 0, val: 1 },
    { x: 2, y: 0, val: 1 }]
    [{ x: 0, y: 1, val: 1 },
    { x: 1, y: 1, val: 1 },
    { x: 2, y: 1, val: 1 }]
    [{ x: 0, y: 2, val: 1 },
    { x: 1, y: 2, val: 1 },
    { x: 2, y: 2, val: 1 }]
];
isiuser = [ { no_anggota: '12345', nama_lahir: ' Agus dwi', tgl_lahir: '04-09-2018'}, 
            { no_anggota: '12345', nama_lahir: 'Septano', tgl_lahir: '15-08-2018'},
            { no_anggota: '12345', nama_lahir: 'Septian putra', tgl_lahir: '15-08-2018'}
        ];

isiseat.forEach((item1) => {
    item1.forEach((item2) => {
        var detaildata = {};
        detaildata.x = item2.x
        detaildata.y = item2.y
        detaildata.val = item2.val
        detaildata.no_anggota = 'ZZZ'
        detaildata.nama_lahir = 'ZZZ'
        detaildata.tgl_lahir = 'ZZZ'
        detaildata.jadwal = req.body.jadwal
        detaildata.section = req.body.section
        var savedata = new DetailBooking(detaildata);
        savedata.save()
    })
});

您可以使用批量插入bulk insert

var dataArray = [];
var isiseat = [
            [
                { x: 0, y: 0, val: 1 },
                { x: 1, y: 0, val: 1 },
                { x: 2, y: 0, val: 1 }
            ],
            [
                { x: 0, y: 1, val: 1 },
                { x: 1, y: 1, val: 1 },
                { x: 2, y: 1, val: 1 }
            ],
            [
                { x: 0, y: 2, val: 1 },
                { x: 1, y: 2, val: 1 },
                { x: 2, y: 2, val: 1 }
            ]
        ]
var bulk = db.items.initializeUnorderedBulkOp();
isiseat.forEach((item1) => {
    item1.forEach((item2) => {
        var detaildata = {};
        detaildata.x = item2.x
        detaildata.y = item2.y
        detaildata.val = item2.val
        detaildata.no_anggota = 'ZZZ'
        detaildata.nama_lahir = 'ZZZ'
        detaildata.tgl_lahir = 'ZZZ'
        detaildata.jadwal = 'sssss'
        detaildata.section = 'sssssss'
        bulk.insert(detaildata);
    })
});
bulk.execute();

我保存的数据看起来像这样

    {
    "_id" : ObjectId("5b61aab063727f69dc5ad1b8"),
    "x" : 0.0,
    "y" : 0.0,
    "val" : 1.0,
    "no_anggota" : "ZZZ",
    "nama_lahir" : "ZZZ",
    "tgl_lahir" : "ZZZ",
    "jadwal" : "sssss",
    "section" : "sssssss"
}

{
    "_id" : ObjectId("5b61aab063727f69dc5ad1b9"),
    "x" : 1.0,
    "y" : 0.0,
    "val" : 1.0,
    "no_anggota" : "ZZZ",
    "nama_lahir" : "ZZZ",
    "tgl_lahir" : "ZZZ",
    "jadwal" : "sssss",
    "section" : "sssssss"
}

如果isiseat和isiuser数组的长度相同，则可以将index参数传递给forEach函数。 (See "Loop through an two arrays simultaneously")

因此，您可以将索引传递给第一个forEach函数：

// Index passed here
isiseat.forEach((item1, index) => {
  item1.forEach((item2) => {
    var detaildata = {
      x: item2.x,
      y: item2.y,
      val: item2.val,
      // ...And then access the `isiuser` array accordingly 
      no_anggota: isiuser[index].no_anggota,
      nama_lahir: isiuser[index].nama_lahir,
      tgl_lahir: isiuser[index].tgl_lahir,
      jadwal: req.body.jadwal,
      section: req.body.section
    };
    // console.log to see results
    console.log(detaildata)
    var savedata = new DetailBooking(detaildata);
    savedata.save()
  })
});

将两个数组输入到Node.js中的对象
