如何在键值对对象中添加文本

How to add text in key value pair Object

我有两个数组数据,我可以将它们转换成一个键值对对象。

firstArray: [] = ['a','b','c','d']
secondArray: [] = [1,2,3,4]

将两个数组转换为键值对的代码:

let dict = firstArray.map(function(obj, index) {
let mydict = {}
mydict[secondArray[index]] = obj;
return mydict;
});

console.log(dict) 
Output: 
 [{
  "1": "a"
}, {
  "2": "b"
}, {
  "3": "c"
}, {
  "4": "d"
}] 

期望的输出:

[{
 value: "1", name: "a"
}, {
value:  "2", name: "b"
}, {
value:  "3",name: "c"
}, {
 value: "4", name:"d"
}]

谁能帮我弄清楚如何实现这个。

const firstArray = ['a','b','c','d'];
const secondArray = [1,2,3,4];

const dict = firstArray.map((i, index) => {
   return {
    value: secondArray[index].toString(),
    name: i
   };     
});
console.log(dict);

我觉得应该可以的

let a = ['a','b','c','d'];
let b = [1,2,3,4];
let tempArray = [];
for(let i = 0;i<a.length;i++){
    
    let tempAttribute = {
        'name' : b[i],
        'value' : a[i]
    }
    tempArray.push(tempAttribute)
}
console.log(tempArray);

因为数据的下标是固定的,我们可以利用它的下标来做一些事情,也可以使用其他的循环方式。

你可以这样做:

const firstArray = ['a','b','c','d']
const secondArray = [1,2,3,4]

const result = firstArray.map((letter, index) => ({
  name: letter, 
  value: secondArray[index].toString()
}))

console.log(result)
