Hello :) See the documentation of the Array class and the splice method :
splice(startIndex:Number <00002026.html#419506>, [deleteCount:Number<00002026.html#419506>], [value:Object <00002035.html#421878>]) The null value don't remove an item in the Array instances :) clean only the value in the case :) If you use a property in an object use 'undefined' or 'delete' : var o = {} ; o.prop1 = 1 ; o.prop2 = 2 ; trace(o) ; for (var prop in o ) { trace( prop + " : " + o[prop] ) ; } trace("--- remove prop1") ; trace( "remove prop1 : " + delete o.prop1 ) ; for (var prop in o ) { trace( prop + " : " + o[prop] ) ; } ... If you want keep the property but this property not must be enumerable in the for..in loop, use ASSetPropFlags : var o = {} ; o.prop1 = 1 ; o.prop2 = 2 ; trace(o) ; ASSetPropFlags(o, ["prop1"] , 1 ) ; // with the for..in for (var prop in o ) { trace( prop + " : " + o[prop] ) ; } // but the property exist : trace(o.prop1 ) ; EKA+ :) 2007/10/19, Andrew Sinning <[EMAIL PROTECTED]>: > > A question in my sent box from when the list went down: > > I like to use the Object class as an index, but there doesn't appear to > be a way to completely remove a property from an object.
