如何存储具有多个值的对象数组 [英] How do I store array of object with many values

问题描述

大家好，

我是javascript的新手，我想为对象存储不同类型的值。

如何为不同的对象存储多个title.usr，如person [0]等

Hello everyone,
I am new to javascript and I want to store different type of values for objects.
How can I store more than one title.usr for different objects like person[0] etc

var title=new Array();
   person.usr=titleValue;
   person.pass=pass;

适合很多人

for many persons

推荐答案

你需要了解 person.usr 与 person [usr] 完全相同。数组和其他对象几乎完全相同： 关联容器 。也许数组的唯一区别是它的预定义属性 length 。



你想要存储标题很奇怪数组。您最好自己存储对象：

You need to understand that person.usr is exactly the same as person["usr"]. Arrays and other objects are pretty much the same thing: associative container. Perhaps the only difference for array is its predefined property length.

It's weird that you want to store titles in the array. You should better store the objects themselves:

var array = [

	{title: "Mr", pass: "I won't tell you"},
	{title: "Mrs", pass: "Get lost!"},
	{species: "Turdus migratorius", genus: "Turdus",
		family: "Turdidae",
		conservationStatus: "least concern"}

];

var someProperty = array[2].family;
   // defined for one array element,
   //not for another one

有问题吗？

Javascript据说是有史以来最容易被误解的语言。请参阅：
