通过字符串 var 获取自定义对象属性 [英] Getting a Custom Objects properties by string var

问题描述

<块引用>

可能的重复:
javascript对象，访问变量属性名?

试图在我的 JS 中变得更高级...

我有一个自定义对象:

Object myObject = new Object();myObject.thing = 任何东西在这里；

我希望能够通过传入一个字符串来检索自定义对象属性...例如:

var propertyString = '东西';警报(myObject.propertyString)；

我不太明白.我已经查看了许多自定义对象的教程 - 但没有任何内容显示如何获取我不知道名称的属性......此外 - 如果可能，我想避免遍历所有属性......

谢谢！！！

解决方案

只需使用myObject['thing'].

Trying to get more advanced in my JS...

I have a custom object:

Object myObject = new Object();

myObject.thing = anythingHere;

I would like to be able to retrieve a custom objects property by passing in a string... eg:

var propertyString = 'thing';
alert(myObject.propertyString);

I can't quite figure that out. I've looked at a number of tutorials for custom objects - but nothing shows how to get properties that I don't know the names of... Also - I would like to avoid looping through all properties if possible...

Thanks!!!

解决方案

Simply use myObject['thing'].
