Google Apps Script - Dynamically Add Remove UiApp Form Elements

Question

I am looking to create a Ui form section in my application that will Dynamically Add Remove UiApp Form Elements. I was trying to use the example from App Script Tutorials here

This example works great as far as performing the add remove elements, but when I use the submit button to capture the values, it submits as a JSON.stringify format. When I just want to capture the values only in a text or string format that will be added to a html email.

If there is way to convert JSON.stringify to text, string or get the values only in format, I will continue to use this example.

If not I was wonder if the following Javascript HTML code can be convert into GAS code and able to capture the values for each entry in a HTML email template to using in MailApp.

Any suggestions, examples or adjustments to the codes would be greatly appreciated.

Thank you in advance

If you don't want the result to be in a JSON object, then you can adjust the _processSubmittedData(e) function. Right now he has it writing everything to an Object, which is fine. All you have to do is have a way to parse it:

  function _processSubmittedData(e){
  var result = {};
  result.groupName = e.parameter.groupName;
  var numMembers = parseInt(e.parameter.table_tag);
  result.members = []; 
  //Member info array
  for(var i=1; i<=numMembers; i++){
        var member = {};
        member.firstName = e.parameter['fName'+i];
        member.lastName = e.parameter['lName'+i];
        member.dateOfBirth = e.parameter['dob'+i];
        member.note = e.parameter['note'+i];
        result.members.push(member);
  }

  var htmlBody = 'Group Name: ' + result.groupName;
  for(var a in result.members) {
    var member = result.members[a];
    var date = member.dateOfBirth;
    var last = member.lastName;
    var first = member.firstName;
    var note = member.note;

    htmlBody += first + ' ' + last + ' was born on ' + date + ' and has this note: ' + note;
  }

  MailApp.sendEmail('fakeEmail@fake.com',"Test Subject Line", "", {htmlBody: htmlBody});
    }
