How to force alpha or numeric inside text fields - LiveCycle Designer 9.0

I am creating a form that requires City, State and Zip.  I need to make sure that users do not put City, State and Zip into the City field; which someone so nicely pointed out to me as a problem with the form.  Anyway, what I am looking for is a way to force the user to only be able to enter alpha characters into the City text field.  I had glanced at the "Validation Patterns" OOTB functionality but I could not find anything listed that would complete the requirement.


Thank you,

    You can use regular expressions in the change:event of the textfield to limit the characters that can be typed in.

    Will allow only digits and the characters A-Z and a-z

    if (xfa.event.newText.match(/[^A-Za-z0-9]/))      

    {

    xfa.event.change = "";

    }

    Hi all,

    I'm using the script below to force numbers only for a phone number field, but it allows the user to press the parentheses and dash characters into the field, perhaps related to auto-fill on the field.  Is there any way of preventing this?


    if (xfa.event.newText.match(/[^0-9]/)) {

      xfa.event.change = "";

    }

    Hi all,

    In addition to my question above, I have another:  I have an e-mail field where all users will be entering the same domain after the "@".  Is there a way to automatically replace the "@" with "@domain.com"?  I have used the code below (and other variations of it, using quotation marks, etc.) and haven't been able to make it work:

    if (xfa.event.newText.match(/[@]/))  {
      xfa.event.change = "@domain.com";
    }

    Great appreciate any help!

    You can use something like:

    if (xfa.event.newText.match(/[\ba-zA-Z0-9._-]+@{1}/g))  {
      xfa.event.change = "@domain.com"; 
    }

    Thanks, Radzmar, it works!  But there's one little issue -- if I press the Backspace key to make a correction, or even type in any other letters, it adds another "@domain.com" with every keystroke.  The only way I have found to get around it is to manually select the entire portion containing all the ampersands and then press Delete.  Any way to solve that?

    I figured it out!  It just needs to be like this:

    //replace @ with "@domain.com"
    if (xfa.event.change == "@") {
      xfa.event.change = "@domain.com";
    }

    So it will generate the suffix string only when you press "@", and it allows corrections without duplication, etc.
