ActionScript Email Validation

by on October 6, 2006 in ActionScript, Programming

Sooner or later you will face with the small quest of validating an email address for your flash application. The following script is a basic script and should not be used for websites that relay heavily on the email address is being requested (shopping carts, credit card transactions and so forth)

ActionScript:
    function isValidEmail(e) {
    if (e.indexOf("@") != -1 && ( e.indexOf(".") > e.indexOf("@") ) ){
    trace("success");
    }else{
    trace("error");
    }
    }

    //Test
    isValidEmail("test@test.com");

    it will return it false …

    How about like this ???
    if (e.indexOf(“@”) != -1 && ( e.lastIndexOf(“.”) > e.indexOf(“@”) ) ) {
    trace(“success”);
    }else{
    trace(“error”);
    }

    // a minimum a@a.us is require
    if ((emailString.indexOf("@") > 0) &&
    (emailString.lastIndexOf(".") > (emailString.indexOf("@") + 1)) &&
    (emailString.lastIndexOf(".")

    [code]
    function is_valid_email(email:String):Boolean {
    var emailRgx:RegExp = /^([a-zA-Z0-9_.-])+@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/;
    ///^[a-zA-Z0-9][-._a-zA-Z0-9]*@([a-zA-Z0-9]*.)+[a-zA-Z]{2,6}$/;
    trace(emailRgx.test(email));
    return emailRgx.test(email);
    }
    is_valid_email("c@j.co");
    [/code]

    Do we need to inport any thing like – import RegExp; for the above code to work?
