如何在 Actionscript 中获取对象的属性列表? [英] How can I get list of properties in an object in Actionscript?

问题描述

我有一个数据提供程序和一个过滤器函数，用于分配给我的数据提供程序的数组.

I have a dataprovider and a filterfunction for my array that's assigned to my dataprovider.

如何在数据提供程序 (item.data) 传递给过滤器函数时获取其每一行中的属性列表?

How can I get a list of the properties that are in each row of the dataprovider (item.data) as it gets passed to the filterfunction?

例如，如果我的对象包含:

For instance, if my object contained:

• 对象
  • 姓名
  • 电子邮件
  • 地址

  然后我希望在我的过滤器功能中能够查看姓名、电子邮件和地址.不幸的是，我不知道这些属性会是什么.

  Then I would want, in my filterfunction to be able to look at name, email and address. Unfortunately, I don't know what these properties will be before hand.

  有什么想法吗?

  推荐答案

  如果是动态对象，我相信你可以这样做:

  If it's a dynamic object I believe you can just do something like this:

  var obj:Object; // I'm assuming this is your object
  
  for(var id:String in obj) {
    var value:Object = obj[id];
  
    trace(id + " = " + value);
  }
  

  这就是它在 AS2 中的做法，我相信这仍然适用于 AS3 中的动态对象.我认为它将显示的属性更多地限制在非动态对象上.

  That's how it's done in AS2, and I believe that still works for dynamic objects in AS3. I think the properties that it will show is more limited on non-dynamic objects.
