Question

是否可以将orders.map中的函数导出为“ order”，并将其导入具有功能的另一个JS文件中？我收到未定义的错误订单。谢谢

main.js

     const getReport = async function() {
      const jsonlUrl = 'https://next.json-generator.com/api/json/get/xxxxx'
      const res = await fetch(jsonlUrl);
      const orders = await res.json();

      const orderlines = orders.map(order => ({

       order_id: order.order_id,

      customer_name: getName()

      }));

---

function.js

const getName = function() {
const customerName = order.customer_name
 return customerName
}

已解决：将参数传递给函数调用

main.js
     const getReport = async function() {
      const jsonlUrl = 'https://next.json-generator.com/api/json/get/xxxxx'
      const res = await fetch(jsonlUrl);
      const orders = await res.json();

      const orderlines = orders.map(order => ({

       order_id: order.order_id,

      customer_name: getName(order)

      }));

我在函数getName上添加了参数

function.js
const getName = function(order) { 
const customerName = order.customer_name 
return customerName 
}

将地图功能导出到其他文件
