js把字符串变成数组

Question

把 s="A,B,C"

变成

[

{

id: 1,

title: 'A',

},

{

id: 2,

title: 'B',

},

{

id: 3,

title: 'C'

}

],

我的方法是

ss = s.split(",");

console.log(ss)

arr = [];

for (var i=1; i<=ss.length; i++) {

a=ss[i]

arr[i]['id']=i;

arr[i]['title']=a;

}

console.log(arr)

但是还是报错

Answer 1

let s = "A,B,C";let arr = s.split(',').map((title, id) => {&nbsp; &nbsp; id++;&nbsp; &nbsp; return { id, title };});
