Validating Email Address.(domain)

I'm Using EmailValidator for Validation:

<mx:EmailValidator id="Email_Validator"
    source="{txtEmail}"
    property="text" required="false"/>

And My Code is:

var isValidForm:Boolean=true;

    var validatorArr:Array = new Array();
    validatorArr.push(Email_Validator);
    var validatorErrorArray:Array = Validator.validateAll(validatorArr);
    isValidForm = validatorErrorArray.length == 0;
    if(isValidForm)
   {
        //.....
   }

It is working fine. But I want domain should be "gmail.com" if some other, validation should return false.. How can I achive this?
I think Regular Expressions are usefull.. But I dont Know to use the same in flex?...

Solution

  • If all you are testing for is "gmail.com", you don't need to use regular expressions at all. A simple

    if (txtEmail.text.indexOf ("gmail.com") < 0) doStuff(); 
// index < 0 => address does not contain search string

    would be enough.

    Nonetheless, ActionScript 3 has the RegExp class to provide regular expression functionality. See this tutorial.
