Javascript，读取具有动态内容的 json 时出现问题

Question

我有一个像这样的json:

[
  {
    "Code": 100
  },
  {
    "Drivers": [
      {
        "RowID": "1",
        "DriverName": "ZZ",
        "DriverAlias": "FF",
        "DriverEmail": "YY@gmail.com",
        "DriverPhone": "1121112229"
      },
      {
        "RowID": "3",
        "DriverName": "OO",
        "DriverAlias": "EE",
        "DriverEmail": "kkk@gmail.com",
        "DriverPhone": "12121458474"
      }
    ]
  }
]

我正在像这样读取 Javascript 中的 json:

for (var i = 0; i < data.length; i++) {  
 Drivers[i] = {
  RowID: data[1].Drivers[i].RowID,
  DriverName: data[1].Drivers[i].DriverName,
  DriverAlias: data[1].Drivers[i].DriverAlias,
  DriverEmail: data[1].Drivers[i].DriverEmail,
  DriverPhone: data[1].Drivers[i].DriverPhone
 };
}

它正在工作，但是当我只有一个像这样的驱动程序的 json 时:

[
  {
    "Code": 100
  },
  {
    "Drivers": [
      {
        "RowID": "1",
        "DriverName": "ZZ",
        "DriverAlias": "FF",
        "DriverEmail": "YY@gmail.com",
        "DriverPhone": "1121112229"
      }
    ]
  }
]

它不起作用，我是否以错误的方式读取 json？谢谢。

Answer 1

试试这个 - 您需要检查数据的长度[1]。驱动程序:

for (var i = 0; i < data[1].Drivers.length; i++) {  
 Drivers[i] = {
  RowID: data[1].Drivers[i].RowID,
  DriverName: data[1].Drivers[i].DriverName,
  DriverAlias: data[1].Drivers[i].DriverAlias,
  DriverEmail: data[1].Drivers[i].DriverEmail,
  DriverPhone: data[1].Drivers[i].DriverPhone
 };
}
