Flex - 为对象属性名称使用变量 [英] Flex - Use Variables for Object Attribute Names

问题描述

如何使用变量访问对象属性?

How do you use variables to access Object attributes?

假设我有一个如下声明的对象，

Suppose I have an Object declared as follows,

var obj:Object = new Object;
obj.Name = "MyName";
obj.Age = "10";

我该怎么做这样的事情，

How would i do something like this,

var fieldName:String = "Name";
var fieldAge:String = "Age";
var Name_Age:String = obj.fieldName + " ," + obj.fieldAge;

上面的代码将fieldName"和fieldAge"视为属性名称本身.我想把它当作一个变量，并将与该变量关联的值映射为 Object 属性名称.

The code above treats 'fieldName' and 'fieldAge' as attribute name itself. I want to treat the same as a variable, and map the value associated with the variable as the Object attribute name.

推荐答案

只需像这样使用方括号:

Just use square brackets like this:

var age:String = obj[fieldAge];
