您好，感谢您对此的见解。

概述

我正在寻找有关如何使用 JavaScript 和 Zapier 应用程序的代码从数组中输出多个对象的建议。到目前为止，我已经能够使用该.split()方法从数组的字符串中提取数据并使用映射数据输出单个对象，但是我无法创建多个对象并将它们作为新数组输出。

编码

 

// My inputData looks like this:
 inputData = INFO [ 'Name1', 'Surname1', 'xxxx@gmail.com', 'phone1', 'Name2', 'Surname2', 'yyyy@gmail.com', 'phone2', 'Name3', 'Surname3', 'zzzz@gmail.com', 'phone3' ]

const participants = inputData.records.split(',')

let i = 0
// Look for every fourth item in the array starting at 0, which represents the participant's First Name
const getName = function(participants, i) {
  for ( i ; i < participants.length; i+=4 ) {
       let name = participants[i]

         return name
    }
  };
// Look for every fourth item in the array starting at 1, which represents the participant's Last Name
const getSurname = function(participants, i) {
  for ( let i = 1; i < participants.length; i+=4 ) {
       let surname = participants[i]

        return surname
    }
  };
// Look for every fourth item in the array starting from 2, which represents the participant's Email Address
const getEmail = function(participants, i) {
  for ( let i = 2; i < participants.length; i+=4 )  {
       let email = participants[i]

        return email
    }
  };

// Output an object inside an array with the key/value pairs as follows
output = {participants: [
{
  first_name: getName(participants, i),
  last_name: getSurname(participants, i),
  email: getEmail(participants, i)
}
]};

示例输出：

participants:
   1:
     first_name: Name1
     last_name: Surname1
     email: xxxx@gmail.com

如果我记录输出，它会正确显示一个对象已创建：

{first_name: 'Name1', last_name: 'Surname1', email: 'xxxx@gmail.com'}

我的挣扎

我正在努力寻找一种方法来迭代 inputData 并提供如下记录：

participants:
   1:
     first_name: Name1
     last_name: Surname1
     email: xxxx@gmail.com
   2:
     first_name: Name2
     last_name: Surname2
     email: yyyy@gmail.com
   3:
     first_name: Name3
     last_name: Surname3
     email: zzzz@gmail.com

  当我console.log()每个函数的输出时，我从for循环中获取每条记录。为什么它不为每个输出记录呢？

所以我设法得到这样的期望输出：

const participants = inputData.records.split(',');
const size = participants.length;

// This sets up the iterator according to the lenght of the 'participants' array
class Sequence {
    constructor( start = 0, end = Infinity, interval = 1 ) {
        this.start = start;
        this.end = end;
        this.interval = interval;
    }
    [Symbol.iterator]() {
        let counter = 0;
        let nextIndex = this.start;
        return  {
            next: () => {
                if ( nextIndex <= this.end ) {
                    let result = { value: nextIndex,  done: false }
                    nextIndex += this.interval;
                    counter++;
                    return result;
                }
                return { value: counter, done: true };
            }
        }
    }
};

let range = new Sequence(0, size - 4, 4);

// Creates an array from the generated Sequence which sets up the iteration count
const startIndex = Array.from(range)

// Create a 'participant' object using the formula
const participant = function(arr, num) {
  let name = participants[num]
  let surname = participants[num+1]
  let email = participants[num+2]
  return {name: name, surname: surname, email: email}
};

// creates an empty array and then pushes the data with every cycle
let participantRecords = []
const participantsList = startIndex.forEach(function(num){
  participantRecords.push(participant(participants, num))
});

                                
output = {participantRecords}
