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

可能重复：

javascript对象，访问变量属性名称？

试图在我的JS中获得更高级......

Trying to get more advanced in my JS...

我有一个自定义对象：

Object myObject = new Object();

myObject.thing = anythingHere;

我希望能够通过传入字符串来检索自定义对象属性...例如：

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

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

我无法理解这一点。我已经查看了一些自定义对象的教程 - 但没有显示如何获取我不知道名称的属性...另外 - 如果可能的话，我想避免遍历所有属性...

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...

谢谢!!!

推荐答案

只需使用 myObject ['thing'] 。
