使用JavaScript/AngularJS将数组转换为对象 [英] Convert array to objects using JavaScript/AngularJS

问题描述

我需要将父数组中的数组转换为对象以匹配数据库模型数据.

I need convert arrays inside my parent array to objects to match my database model data.

我有这样的数组:

emails: Array[2] 
0: "[e-mail]"
1: "[e-mail]"
id: 1 
firstname: "Jane"
lastname: "Doe

我要实现的是将电子邮件数组转换为这样的对象数组:

What I want to achieve is to convert emails array to array of objects like this:

    emails: Array[2] 
    0: 
{
name: "[e-mail]"
}
    1: 
{
name: "[e-mail]"
}
    id: 1 
    firstname: "Jane"
    lastname: "Doe

我试图使用此代码将数组转换为对象，但是由于某种原因它失败(不显示任何数据->变量rv为空):

I tried to use this code to convert array to object but for some reason it fails (no data are displayed -> variable rv is empty):

 var rv = {};
        for (var i = 0; i < dbInfo.emails.length; ++i)
            if (dbInfo.emails[i] !== undefined) rv[i] = dbInfo.emails[i];

有人知道我的代码为什么失败，有人知道这种类型的问题的解决方案吗?

Does someone knows why my code fails and does someone knows solution for this type of problem?

感谢前进.

推荐答案

这是Array.prototype.map函数的完美用法:

dbInfo.emails = dbInfo.emails.map(function(e) {
    return { name: e };
});

即只需将数组(e)的每个元素转换为对象{ name: email }

i.e. just convert each individual element of the array (e) into an object { name: email }
