javascript - 如何重新排列 CSV/JSON 键列？ (JavaScript)

Question

我正在使用 Papa Parse JavaScript 库将 JSON 对象数组转换为 CSV。有没有办法以某种方式排列 CSV 列。

例如；我得到的列是:

OrderStatus、canOp、OpDesc、ID、OrderNumber、FinishTime、UOM、StartTime

但希望安排为:

ID、OrderNumber、OrderStatus、StartTime、FinishTime、canOp、OpDesc、UOM

之所以我得到的 CSV 是未排列的，是因为 JSON 数据看起来像这样:

json = [
{
    OrderStatus: "Good",
    canOp:"True",
    OpDesc:"Good to go",
    ID:"100",
    OrderNumber:"1000101",
    FinishTime:"20:50",
    UOM:"K",
    StartTime:"18:10"
},
...
]

谢谢

Papa Parse 允许在 unparse() 函数中指定字段的顺序:

var csv = Papa.unparse({
  fields: ["ID", "OrderNumber", "OrderStatus", "StartTime", "FinishTime", "canOp", "OpDesc", "UOM"],
  data: [{
      OrderStatus: "Good",
      canOp: "True",
      OpDesc: "Good to go",
      ID: "100",
      OrderNumber: "1000101",
      FinishTime: "20:50",
      UOM: "K",
      StartTime: "18:10"
    },
    // ...
  ]
});

console.log(csv);
