如何删除从一个基于对象的关联数组中的Flex 3的值？

问题描述

我需要删除与在Flex 3关联数组属性关联的值;这可能吗？

I need to remove the value associated with a property in a Flex 3 associative array; is this possible?

例如，假设我创建了这个阵列像这样：

For example, suppose I created this array like so:

var myArray:Object = new Object();
myArray[someXML.@attribute] = "foo";

后来，我需要做的是这样的：

Later, I need to do something like this:

delete myArray[someXML.@attribute];

不过，我得到这个错误信息在运行时：

However, I get this error message at runtime:

Error #1119: Delete operator is not supported with operand of type XMLList.

我如何执行此操作？

How do I perform this operation?

推荐答案

删除不这样做，因为它在AS2做尽可能多的在AS3：

delete doesn't do as much in AS3 as it did in AS2:

不过，我认为你的问题可能只需使用的toString（），即可以解决

However, I think your problem might be solved by simply using toString(), i.e.

var myArray:Object = new Object();
myArray[[email protected]()] = "foo";

delete myArray[[email protected]()];
