Hi,
I've got the solution now. I'll post it, if someone needs it in the
future:
In general: I've a ArrayCollection "validators" where I put all my
validators in (when I create them (dynamically)).
On creation of my FormItems (i.e. a TextInput called "editor"), I add
the following two EventListeners:
editor.addEventListener(Event.CHANGE, validateForm);
editor.addEventListener(Event.CHANGE, turnOnOneValidator);
Then my ActionScript functions for validation:
/**
* validates all form elements. in allValid all return values from each
validation are boolean combined
* (if a single element returns false, everything is false
*/
internal function validateForm():Boolean {
var result:ValidationResultEvent = null;
var allValid:Boolean = true;
for(var i:Number=0; i<validators.length; i++) {
result = validators.getItemAt(i).validate();
if(result.results != null) {
allValid = false;
result = null;
}
}
return allValid;
}
/**
* disables all validators
* simulates a ValidationResultEvent with VALID for each control (all
red borders will disappear)
*/
internal function turnOffValidators():void {
for(var i:Number=0; i<validators.length; i++) {
validators.getItemAt(i).enabled = false;
var evt:ValidationResultEvent = new
ValidationResultEvent(ValidationResultEvent.VALID);
validators.getItemAt(i).source.validationResultHandler(evt);
}
}
/**
* enables all validators
*/
internal function turnOnValidators():void {
for(var i:Number=0; i<validators.length; i++) {
validators.getItemAt(i).enabled = true;
}
}
/**
* turns on a specific validator (the one from event.target)
* if there's a control changed and the input won't validate, it should
be marked with a red border,
* event if the entire form has disabled validators
*/
internal function turnOnOneValidator(event:Event):void {
for(var i:Number=0; i<validators.length; i++) {
if(validators.getItemAt(i).source == event.target) {
validators.getItemAt(i).enabled = true;
}
}
}
I hope, this may help someone too :-)
You've to play around, when to enable and disable your validators, but I
think, you'll get this!
Bye,
Fritz
