[RESOLVED] restricting input text when a @ sign is not present

[capdetrons]

Hi,

I'm looking for a tutorial where this would be explained. Obviously for an email input field to have the user rewrite it.

Thanks for any suggestions

Hi Cap,

I think you are looking for a mail form basically, with email check function, maybe tyry this simple example.

2 text fields, Email.text / Errors.text
1 button, sendButton

code:

// *** text fields
Errors.text = "";
Email.text = "";
// *** check valid email
function Validate(address)
{
    if (address.length >= 7)
    {
        if (address.indexOf("@") > 0)
        {
            if ((address.indexOf("@") + 2) < address.lastIndexOf("."))
            {
                if (address.lastIndexOf(".") < (address.length - 2))
                {
                    return (true);
                }
            }
        }
    }
    return (false);
}
// ** check all form details then send
function FormCheck()
{
    if (Email.text.length < 1)
    {
        Errors.text = "Please enter an E-Mail.";
    }
    else if (!Validate(Email.text))
    {
        Errors.text = "Please enter a valid E-Mail.";
    }
    else
    {
        Errors.text = "E-mail good to go";
        // now send the mail code
    }
}
// *** send button
sendButton.onRelease = FormCheck;
