从数组中获取速率- json

[
  {
    "device": "Device A",
    "rate": 100
  },
  {
    "device": "Device B",
    "rate": 200
  },
  {
    "device": "Device C",
    "rate": 150
  }
]

// 假设jsonArray是包含速率信息的JSON数组
var jsonArray = [
  {
    "device": "Device A",
    "rate": 100
  },
  {
    "device": "Device B",
    "rate": 200
  },
  {
    "device": "Device C",
    "rate": 150
  }
];

// 遍历数组并获取速率
for (var i = 0; i < jsonArray.length; i++) {
  var device = jsonArray[i].device;
  var rate = jsonArray[i].rate;
  console.log("设备：" + device + "，速率：" + rate);
}

设备：Device A，速率：100
设备：Device B，速率：200
设备：Device C，速率：150
