Question

我一直在搞这样的事情但在终端 executed 时未定义，

"Line1": "---------------------Project Information---------------------",

`在我＆gt;之后，我怎样才能正确地在终端中打印虚线？运行我的js文件解析下面的json数据？

{

  "Line1": "---------------------Project Information---------------------",

  "CustomerNumber1": "Customer Number: 1125\n",

  "CustomerName1": "Customer Name: John Smith\n",

  "PackageNumber1": "Package Number: 011\n",

  "Trip Cost1": "Trip Cost: $3760\n",

  "Line2": "------------------------------------------------------------", 

  "CustomerNumber2": "Customer Number: 1234\n",

  "CustomerName2": "Customer Name: Jerry Smith\n",

  "PackageNumber2": "Package Number: 011\n",

  "Trip Cost2": "Trip Cost: $2899\n",

  "Line3": "------------------------------------------------------------",

  "CustomerNumber3": "Customer Number: 1324\n",

  "CustomerName3": "Customer Name: Andreas Smith\n",

  "PackageNumber3": "Package Number: 011\n",

  "Trip Cost3": "Trip Cost: $1199\n",

  "Line4": "------------------------------------------------------------"


}

您的JSON数据应该只存储原始数据，而不是任何格式。在您的情况下，您应该有一个对象数组，每个对象都有属性：

[
  {
    "CustomerNumber": 1125,
    "CustomerName": "John Smith",
    "PackageNumber": "011",
    "Trip Cost": 3760
  },
  {
    "CustomerNumber": 1234,
    "CustomerName": "Jerry Smith",
    "PackageNumber": "011",
    "Trip Cost": 2899
  },
  {
    "CustomerNumber": 1324,
    "CustomerName": "Andreas Smith",
    "PackageNumber": "011",
    "Trip Cost": 1199
  }
]

然后，您可以在打印数据时让代码添加格式：

var list = JSON.parse(/* your JSON string */);
console.log("---------------------Project Information---------------------");
for (var i = 0; i < list.length; i++) {
  var obj = list[i];
  console.log("Customer Number: "+obj["CustomerNumber"]);
  console.log("Customer Name: "+obj["CustomerName"]);
  console.log("Package Number: "+obj["PackageNumber"]);
  console.log("Trip Cost: $"+obj["Trip Cost"]);
  console.log("------------------------------------------------------------");
}

var list = [
  {
    "CustomerNumber": 1125,
    "CustomerName": "John Smith",
    "PackageNumber": "011",
    "Trip Cost": 3760
  },
  {
    "CustomerNumber": 1234,
    "CustomerName": "Jerry Smith",
    "PackageNumber": "011",
    "Trip Cost": 2899
  },
  {
    "CustomerNumber": 1324,
    "CustomerName": "Andreas Smith",
    "PackageNumber": "011",
    "Trip Cost": 1199
  }
];
console.log("---------------------Project Information---------------------");
for (var i = 0; i < list.length; i++) {
  var obj = list[i];
  console.log("Customer Number: "+obj["CustomerNumber"]);
  console.log("Customer Name: "+obj["CustomerName"]);
  console.log("Package Number: "+obj["PackageNumber"]);
  console.log("Trip Cost: $"+obj["Trip Cost"]);
  console.log("------------------------------------------------------------");
}
