You want to validate an email address on your Adobe LiveCycle Designer Form ? No problem, just follow the following small tutorial.
Create a new Form. Add a Text Field to it. (so far so good 😉 ) Go into the Object > Value window of the Text field Choose > validation Script Message (error) Create a nice little message saying that the mail address is wrong. Go into the Script Editor (CTRL-SHIFT-F5). Put in this little script as a JavaSscipt (run at Client)
var r = new RegExp();
var result = r.test(this.rawValue);
if (result == true)
Add a button that validates your form like the Email Submit Button.
And test it ! 😉
