Question

我有一个数组中的电子邮件列表：

["gomand@gmail.com", "terry@yahoo.com", "123Yu@gmail.com"]

如何遍历数组并将每封电子邮件作为自己的属性推送到对象中：对象看起来像：

{
email1: "gomand@gmail.com",
email2: "terry@yahoo.com",
email3: "123Yu@gmail.com"
}

Answer 1

一个班轮：

var object = ['gomand@gmail.com', 'terry@yahoo.com', '123Yu@gmail.com'].reduce((r, e, i) => (r['email'+(i+1)] = e, r), {});

Answer 2

var inputArr = ['gomand@gmail.com', 'terry@yahoo.com', '123Yu@gmail.com'];
var outputObj = {};
var i;

for (i=0; i<inputArr.length; i++) {
    outputObj['email'+i] = inputArr[i];
}

console.log(outputObj);

Answer 3

这应该这样做：

var arr = ["gomand@gmail.com", "terry@yahoo.com", "123Yu@gmail.com"];
var emails = {}; 
arr.forEach((e, i) => emails["email" + (i+1)] = e);
console.log(emails);

Answer 4

您可以使用Array#reduce轻松完成此操作：

＆＃13;

var emails = ['gomand@gmail.com', 'terry@yahoo.com', '123Yu@gmail.com']

var result = emails.reduce(function (o, e, i) {
  o['email' + ++i] = e
  return o
}, {})

console.log(result)

＆＃13;

Answer 5

你可以试试这个

var ary = [];

function pushToAry(name, val) {
   var obj = {};
   obj[name] = val;
   ary.push(obj);
}

pushToAry("myName", "myVal"); // Here it is for single value u can loop with your array.

Answer 6

这是Array.prototype.reduce为

做的

＆＃13;

const emails = ['gomand@gmail.com', 'terry@yahoo.com', '123Yu@gmail.com']
console.info(emails.reduce((map, email, idx) =>
  Object.assign(map, { ['email' + (idx + 1)]: email }), Object.create(null)))

＆＃13;

Answer 7

这是另一种解决方案

＆＃13;

var emails = ["gomand@gmail.com", "terry@yahoo.com", "123Yu@gmail.com"];
var object = {}; 
emails.forEach(function(value, key){
      object["email" + (key+1)] = value;
});

console.log(object);

＆＃13;

Answer 8

obj = {};
for(i=0;i<yourArray.length;i++){
propName = 'email' + i;
obj[propName] = yourArray[i];
}

我相信这应该有用。
