如何在javascript中将数据从旧json复制到新json？

Question

我有一个 json。如果提供程序是“AXIS DATA”，我需要将“数据”的内容复制到新的 json 文件中。如何？

我试过的是

首先，我json.parse使用 for 循环进行转换和搜索。

到目前为止，这是我的代码

var hasilsearching = {};
var hasildata = JSON.parse( FIRST JSON );
for (var i=0 ; i < hasildata.data.length ; i++){
    if (hasildata.data[i].provider == "AXIS DATA") {
        hasilsearching = hasildata.data[i];
    }   
}

但不是我所期望的。我知道里面if()是问题所在。但我不知道。

这是我的 json 文件

{
    "errNumber": "0",
    "userID": "EKL0003097",
    "data": [
        {
            "code": "BXD1",
            "price": "15000.00",
            "name": "Voucher Axis Aigo 1GB 24J 30H",
            "ep": "770",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "AXIS DATA"
        },
        {
            "code": "BXD2",
            "price": "25000.00",
            "name": "Voucher Axis Aigo 2GB 24J 30H",
            "ep": "660",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "AXIS DATA"
        },
    {
            "code": "BOLT1",
            "price": "31000.00",
            "name": "Bolt Kuota 1,5GB 24Jam 30hr",
            "ep": "1320",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "BOLT"
        },
        {
            "code": "BOLT3",
            "price": "50000.00",
            "name": "Bolt Kuota 3GB 24Jam 30hr",
            "ep": "1127",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "BOLT"
        }
    ],
    "respMessage": "PROSES BERHASIL"
}

这是预期的新 json 文件

{
    "data": [
        {
            "code": "BXD1",
            "price": "15000.00",
            "name": "Voucher Axis Aigo 1GB 24J 30H",
            "ep": "770",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "AXIS DATA"
        },
        {
            "code": "BXD2",
            "price": "25000.00",
            "name": "Voucher Axis Aigo 2GB 24J 30H",
            "ep": "660",
            "isActive": "Active",
            "type": "KUOTA",
            "provider": "AXIS DATA"
        }
    ]
}

将一个空数组添加到data的属性hasilsearching以及push以下任何匹配项：

var hasildata = {"errNumber":"0","userID":"EKL0003097","data":[{"code":"BXD1","price":"15000.00","name":"Voucher Axis Aigo 1GB 24J 30H","ep":"770","isActive":"Active","type":"KUOTA","provider":"AXIS DATA"},{"code":"BXD2","price":"25000.00","name":"Voucher Axis Aigo 2GB 24J 30H","ep":"660","isActive":"Active","type":"KUOTA","provider":"AXIS DATA"},{"code":"BOLT1","price":"31000.00","name":"Bolt Kuota 1,5GB 24Jam 30hr","ep":"1320","isActive":"Active","type":"KUOTA","provider":"BOLT"},{"code":"BOLT3","price":"50000.00","name":"Bolt Kuota 3GB 24Jam 30hr","ep":"1127","isActive":"Active","type":"KUOTA","provider":"BOLT"}],"respMessage":"PROSES BERHASIL"};

var hasilsearching = { data: [] };
for (var i=0 ; i < hasildata.data.length ; i++){
  if (hasildata.data[i].provider == "AXIS DATA") {
    hasilsearching.data.push(hasildata.data[i]);
  }   
}

console.log(hasilsearching);

.as-console-wrapper { max-height: 100% !important; top: auto; }

它也更容易使用filter：

var hasildata = {"errNumber":"0","userID":"EKL0003097","data":[{"code":"BXD1","price":"15000.00","name":"Voucher Axis Aigo 1GB 24J 30H","ep":"770","isActive":"Active","type":"KUOTA","provider":"AXIS DATA"},{"code":"BXD2","price":"25000.00","name":"Voucher Axis Aigo 2GB 24J 30H","ep":"660","isActive":"Active","type":"KUOTA","provider":"AXIS DATA"},{"code":"BOLT1","price":"31000.00","name":"Bolt Kuota 1,5GB 24Jam 30hr","ep":"1320","isActive":"Active","type":"KUOTA","provider":"BOLT"},{"code":"BOLT3","price":"50000.00","name":"Bolt Kuota 3GB 24Jam 30hr","ep":"1127","isActive":"Active","type":"KUOTA","provider":"BOLT"}],"respMessage":"PROSES BERHASIL"};

var hasilsearching = { data: hasildata.data.filter(({ provider }) => provider == "AXIS DATA") };

console.log(hasilsearching);

.as-console-wrapper { max-height: 100% !important; top: auto; }
