Question

我有这种格式的数组

0:["Emp Code", "Reportee Name", "Product", "Target", "Achievement","percentage"]

1:["1000001", "Harry", "Product A ", "116", "110", "94.82758621"]

2:["1000001", "Harry", "Product B", "94", "100", "106.3829787"]

3:["1000001", "Peter", "Product A ", "105", "104", "99.04761905"]

4:["1000001", "Peter", "Product B", "114", "110", "96.49122807"]

想要这样

[
"Emp Code":{
       "1000001", 
        "Harry", 
       "Product A ",
        "116", 
       "110",
        "94.82758621"
     },
"Reportee Name":{
       "1000001", 
        "Harry", 
       "Product B ",
        "94", 
       "100",
        "106.3829787"
     },
   ....
]

Answer 1

假设您要使用数组中的第一项作为键，并且要使用该位置的数据作为键的值：

const input = [
  ["Emp Code", "Reportee Name", "Product", "Target", "Achievement","percentage"],
  ["1000001", "Harry", "Product A ", "116", "110", "94.82758621"],
  ["1000001", "Harry", "Product B", "94", "100", "106.3829787"],
  ["1000001", "Peter", "Product A ", "105", "104", "99.04761905"],
  ["1000001", "Peter", "Product B", "114", "110", "96.49122807"],
]

const getDataAtPosition = (data, i) => data.map(item => item[i])

const transform = data => data[0].reduce((prev, curr, i) => {
  const thisDataWithTitle = getDataAtPosition(data, i);
  const dataToUse = thisDataWithTitle.slice(1, thisDataWithTitle.length);
  prev[curr] = dataToUse;
  return prev;
}, {})

const test = transform(input)

console.dir(test)

Answer 2

假设您想要一个对象数组，第一个数组作为键，后面的作为值，则可以通过将第一行作为键来映射切片的值。

var array = [["Emp Code", "Reportee Name", "Product", "Target", "Achievement", "percentage"], ["1000001", "Harry", "Product A ", "116", "110", "94.82758621"], ["1000001", "Harry", "Product B", "94", "100", "106.3829787"], ["1000001", "Peter", "Product A ", "105", "104", "99.04761905"], ["1000001", "Peter", "Product B", "114", "110", "96.49122807"]],
    [keys, ...data] = array,
    result = data.map(a => Object.assign(...keys.map((k, i) => ({ [k]: a[i] }))));
    
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
