如何从 Flex 3 中基于对象的关联数组中删除值? [英] How do I delete a value from an Object-based associative array in Flex 3?

问题描述

我需要删除与 Flex 3 关联数组中的属性关联的值；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，假设我像这样创建了这个数组:

For example, suppose I created this array like so:

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

稍后，我需要做这样的事情:

Later, I need to do something like this:

delete myArray[someXML.@attribute];

但是，我在运行时收到此错误消息:

However, I get this error message at runtime:

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

如何执行此操作?

推荐答案

删除在 AS3 中的作用不如在 AS2 中那么多:

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

但是，我认为您的问题可以通过简单地使用 toString() 来解决，即

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

var myArray:Object = new Object();
myArray[[e-mail]()] = "foo";

delete myArray[[e-mail]()];
