将字符串数组转换为对象数组

Question

我有这个结构：

materials= ["a","b","c"]

我需要它是这样的：

data= [{material:"a"},{material:"b"},{material:"c"}]

Answer 1

您可以使用map方法。

 var materials= ["a","b","c"] console.log(materials.map(material => ({material})));

Answer 2

您可以使用map ：

materials.map(a=> ({material: a}))

一个例子：

 let materials= ["a","b","c"]; const result = materials.map(a=> ({material: a})) console.log(result)

甚至更短（感谢Ele ）：

materials.map(material => ({material}));

 let materials= ["a","b","c"]; const result = materials.map(material => ({material})); console.log(result)

Answer 3

您可以使用Array.forEach() ：

 var materials= ["a","b","c"] var res = []; materials.forEach((a) => res.push({material: a})); console.log(res);

Answer 4

const obj = materials.map((material)=>{
               return ({"material": material})
             });

console.log(obj);

Answer 5

我会使用 Array.map：

 const test = ["a", "b", "c"]; const result = test.map(e => { return { material: e }; }); console.log(test); console.log(result);

Answer 6

let materials= ["a","b","c"]
let newObj = materials.map(material => ({material}));
console.log(newObj);
