Question

I have a dynamic ActionScript Class that is used to send parameters to a WebService. Some of these parameters are always present, so they are public properties of the Class:

package {     [Bindable]     public dynamic class WebServiceCriteria     {         public var property1:int;          public var property2:String;          public var property3:String;          public var property4:String;     } } 

But, I am also adding properties at runtime that can change over time:

criteria.runTimeProperty = '1'; 

I’m not very familiar with using dynamic classes, so I was wondering if it is possible to ‘remove’ the new property. Let’s say the next time I call the WebService I don’t want that property sent – not even as a null. How can I remove it from the Class instance without creating a new instance each time?

Answer 1

I believe all you’d need to do is this:

delete criteria.runTimeProperty; 

or

delete criteria['runTimeProperty']; 

Either should do the same thing.

See the delete documentation for specifics.
