Email address field Validation

[Lakshminarayan K V]

Hello

 

I have created PDF form.  In that, I have a field for entering the email address. I would like to validate the email address field to check whether valid email address is entered or not.  '@' should be entered and only once

 

Can anyone help?

 

Thanks in advance

Laks,

 

I made a small changes on the regular expression in the code I sent you the other day. It should work for this case now. Just let you know that to fully validate an email address is a lot more than just checking the “@”. You can google it. It should be a pretty complex regular expression.

 

if (!event.value) {

    event.rc = true;

}

else {

    var s = new String(event.value);

    if (s.match(/^[^@]+@[^@]+$/)) {

        event.rc = true;

    }

    else {

        app.alert("Invalid email address");

        event.rc = false;
