Susan,
The
reason that it is not static is because most validators have properties that
help define the validation rules. For example, the Number validator has a maxValue
and minValue property. Also, you can customize the error messages for each
validator. Thus, we need instances of the validators to accomplish this.
As for the errorString
property, it is better to use the UIComponent.validationResultHandler function
instead. Just pass in the results from the validate() function.

Validator woes
Jason,
Thanks. I guess I just got mixed up since it's a little unnatural to
instantiate a class to call a method that should be static! Also,
adding text to the errorString field automatically sets everything
redhere's my method should anyone search upon this message at a
future date:
private function validateField() : void {
var emails : Array = toField.text.split(,);
for(var j:uint=0; j emails.length; j++)
{
var emailVal : EmailValidator = new EmailValidator();
var valResult : ValidationResultEvent =
emailVal.validate(emails[j]);
if(valResult.type == ValidationResultEvent.INVALID)
{
toField.errorString=' + emails[j] + ' is not a valid
e-mail address.;
return;
}
}
}

Suzy,
The listener, source and trigger are all optional properties
of Validators. You can just call the validate() function. Pass in the
string you want to validate and it will return the ValidationResult. The
validate() function is on the base class, Validator.

Subject: [flexcoders] Custom Validator woes
I'm building an e-mail client where the To: field can have a
comma
delimited array of e-mail addresses: [EMAIL PROTECTED]
mailto:bob%40yahoo.com , [EMAIL PROTECTED] mailto:sarah%40yahoo.com
I have the validation occuring in the focusOut event, where I split
the To: field so I get an Array of e-mail addresses.
var emails : Array = value.split(,);
I then want to loop through and validate each value. However, there is
no easy way to do this using the Flex SDK EmailValidator.as.
Ideally, I would think I could call a static method which would return
me a ValidationResultEvent, which I could then add to my component.
However, everything with the SDK EmailValidator class requires a
listener/source/trigger to be bound to it and no matter what I try to
doit looks at that To: field as one big String...I can't
give it
just the iterated split value.
Any ideas on this?? Is there a way to statically call a method without
having to pass in a reference to the EmailValidator object?
