计算字典长度的Flex [英] Calculating Dictionary length in Flex

问题描述

什么是计算在Flex中Dictionary对象的长度，最好的方法是什么？

What's the best way to calculate the length of a Dictionary object in Flex?

var d:Dictionary = new Dictionary();
d["a"] = "alpha";
d["b"] = "beta";

我要检查它应该是2本字典的长度。有没有办法做到这一点除了通过对象循环？

I want to check the length which should be 2 for this Dictionary. Is there any way to do it other than looping through the objects?

推荐答案

没有，有没有办法来检查对象的长度（意思是pretty的多，支持非字符串键的对象）比循环等通过元素

No, there is no way to check the length of an object(Dictionary is pretty much an object that supports non-String keys) other than looping through the elements.

您可能不担心检查，如果该属性是内部的。

You probably don't have to worry about checking if the property is an internal one.
