Remove items from Flex ArrayCollection
var alerts:ArrayCollection = new ArrayCollection();
for (var i:int = alerts.length; i > 0; i--)
{
var alert:Alert = alerts.getItemAt(i-1) as Alert;
if (alert.parentName == parentName)
{
alerts.removeItemAt(i-1);
}
}
Note: alerts.length is initialized once and thus does not vary, on the contrary of:
for (var i:int =0; i < alerts.length; i++)
for (var i:int = alerts.length; i > 0; i--)
{
var alert:Alert = alerts.getItemAt(i-1) as Alert;
if (alert.parentName == parentName)
{
alerts.removeItemAt(i-1);
}
}
Note: alerts.length is initialized once and thus does not vary, on the contrary of:
for (var i:int =0; i < alerts.length; i++)
