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+ :)
