Adding additonal javascript acction to existing javascript on PC with ADOBE Acrobat PRO XI

PC, Windows 10, Adobe Acrobat PRO XI

var patternEmpty = /^\s*$/;

var strMissing = "";

if(patternEmpty.test(this.getField("1st
purchaser").value))

     strMissing =
"1st purchaser";

  { // All is ok,
submit the data

1. console.println("All form data ok");

  }

if(strMissing.length)

{// Got an error

1. app.alert("Please complete 1st Purchaser: " +
   strMissing);

}

this is the script currently in use and is functioning as desired.  I want to add an action that when the approver hits the submit button it will cc: the email address entered in the EMAIL field completed by the originator of the form?
