Email and cell phone validation in AS2 and AS3
I just wrote 2 simple classes to validate email addresses and Belgian cell phone numbers in AS2 and AS3.
Might come in handy for you, they’re available for download here.
I included FLA’s for Flash8 and FlashCS3 for AS2 and AS3.
They show 2 TextInput components, one for an email address and one for a cell phone number.
The cell phone validation includes a “strip” function. Since people tend to enter their phone numbers in different ways, dots, blanks and slashes are removed from the input before validating the number.
AS2 Usage example:
import be.boulevart.as2.validation.Email;
import be.boulevart.as2.validation.GSM;
class be.boulevart.as2.playfield.Validation extends MovieClip
{
// Elements on Stage
private var check_btn:Button;
private var email_ti, phone_ti:TextInput;
private var emailOk:Boolean;
private var gsmOk:Boolean;
public function Validation() {}
private function onLoad():Void
{
check_btn.addEventListener("click", Delegate.create(this, doValidation));
email_ti.tabIndex = 1;
phone_ti.tabIndex = 2;
check_btn.tabIndex = 3;
}
private function doValidation():Void
{
emailOk = Email.validate(email_ti.text);
gsmOk = GSM.validate(phone_ti.text);
if(!emailOk)
{
Alert.show("Invalid email address!", "Error", Alert.OK, this);
} else {
Alert.show("Email address is valid!", "You rock dude", Alert.OK, this);
}
if (!gsmOk)
{
Alert.show("Invalid cell phone number!", "Error", Alert.OK, this);
}
else
{
Alert.show("Cell phone number is valid!", "You rock dude", Alert.OK, this);
}
}
}
import be.boulevart.as2.validation.GSM;
class be.boulevart.as2.playfield.Validation extends MovieClip
{
// Elements on Stage
private var check_btn:Button;
private var email_ti, phone_ti:TextInput;
private var emailOk:Boolean;
private var gsmOk:Boolean;
public function Validation() {}
private function onLoad():Void
{
check_btn.addEventListener("click", Delegate.create(this, doValidation));
email_ti.tabIndex = 1;
phone_ti.tabIndex = 2;
check_btn.tabIndex = 3;
}
private function doValidation():Void
{
emailOk = Email.validate(email_ti.text);
gsmOk = GSM.validate(phone_ti.text);
if(!emailOk)
{
Alert.show("Invalid email address!", "Error", Alert.OK, this);
} else {
Alert.show("Email address is valid!", "You rock dude", Alert.OK, this);
}
if (!gsmOk)
{
Alert.show("Invalid cell phone number!", "Error", Alert.OK, this);
}
else
{
Alert.show("Cell phone number is valid!", "You rock dude", Alert.OK, this);
}
}
}
AS3 Usage example:
package be.boulevart.as3.playfield
{
import be.boulevart.as3.validation.Email;
import be.boulevart.as3.validation.GSM;
import flash.display.MovieClip;
import flash.events.*;
public class Validation extends MovieClip
{
protected var emailOk:Boolean;
protected var gsmOk:Boolean;
public function Validation()
{
check_btn.addEventListener("click", doValidation);
email_ti.tabIndex = 1;
phone_ti.tabIndex = 2;
check_btn.tabIndex = 3;
}
private function doValidation(evt:Event):void
{
emailOk = Email.validate(email_ti.text);
gsmOk = GSM.validate(phone_ti.text);
if(!emailOk)
{
trace("Invalid email address!");
email_result.text = "Invalid email!";
}
else
{
trace("Email address is valid!");
email_result.text = "Valid email!";
}
if (!gsmOk)
{
trace("Invalid cell phone number!");
phone_result.text = "Invalid phone!";
}
else
{
trace("Cell phone number is valid!");
phone_result.text = "Valid phone!";
}
}
}
}
{
import be.boulevart.as3.validation.Email;
import be.boulevart.as3.validation.GSM;
import flash.display.MovieClip;
import flash.events.*;
public class Validation extends MovieClip
{
protected var emailOk:Boolean;
protected var gsmOk:Boolean;
public function Validation()
{
check_btn.addEventListener("click", doValidation);
email_ti.tabIndex = 1;
phone_ti.tabIndex = 2;
check_btn.tabIndex = 3;
}
private function doValidation(evt:Event):void
{
emailOk = Email.validate(email_ti.text);
gsmOk = GSM.validate(phone_ti.text);
if(!emailOk)
{
trace("Invalid email address!");
email_result.text = "Invalid email!";
}
else
{
trace("Email address is valid!");
email_result.text = "Valid email!";
}
if (!gsmOk)
{
trace("Invalid cell phone number!");
phone_result.text = "Invalid phone!";
}
else
{
trace("Cell phone number is valid!");
phone_result.text = "Valid phone!";
}
}
}
}
Enjoy!

Hi, just had a look at your email validator – it doesn’t allow the apostrophe or accented characters does it? So k.o’connor@somedomain.com would fail the test.
In fact, it doesn’t like my email address either. It doesn’t seem to like email addresses where the first part is only 3 chars long, which is the case with me.
Hope you find this helpful.

this seems to fix it
charAt(i) instead of charAt(j)!
private static function checkFirstLevelDomainChars (s:String, i:Number, l:Number):Boolean {
while (i
