How to remove a value from an Object-based associative array in Flex 3?

Question

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

For example, suppose I created this array as follows:

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

Later I need to do something like this:

 delete myArray[ someXML.@attribute ]; 

However, I get this runtime error message:

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

How to perform this operation?

Answer 1

delete does not do as much in AS3 as it does in AS2:

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

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

Answer 2

Instead of deleting it, try setting it to null.

 myArray[ someXML.@attribute ] = null; 

Thus, it will be the same as any other value in an array that is not defined.
