Special Characters in a Text Variable

Is there a way to limit a text field to just text and numbers? I have a comments field in a form that is stored in a variable as multiple lines of text and then the text is sent in an email. I believe the variable did not populate based upon some of the special characters entered.

Re: Special Characters in a Text Variable

Yes. You can do it. but only for a multiline text field with Plain Text. 

1. Just assign control id your comment field as shown in below screen

2. Then add following script in custom javascript:

NWF.FormFiller.Events.RegisterAfterReady(function () {
              var ctrlComment = NWF$("#" + ctrlID_Comment);
              if(ctrlComment){
                  NWF$(ctrlComment).keypress(function (e) {
                     var regex = new RegExp("^[a-zA-Z0-9\s]+$");
                     var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
                     if (regex.test(str)) {
                            return true;
                     }
                    e.preventDefault();
                   return false;
              });
           }
      });

I just allowed text and number. You can also change regular expression according to your requirement.

Let me know if you want sample form for this.

Hope it will help

Re: Special Characters in a Text Variable

Hi, thanks for the information. I think the characters that are causing the text not to show are [ and ]. Is there a listing of the characters that might cause the error in setting the variable other than these 2 characters? Also, is there a way to not allow these characters but allow all others (so I guess it would almost be the opposite of what you have)? Thanks again.
