google apps script - Get the current response onSubmit

Question

Is there any way to find out the current response of the Google Form (programmatically)?

In the onSubmit function.

Looked over their documentation but I have to provide the respondId.

How do I find the respondId?

A snipped code from them about this is:

// Open a form by ID and log the responses to each question.
 var form = FormApp.openById('1234567890abcdefghijklmnopqrstuvwxyz');
 var formResponses = form.getResponses();
 for (var i = 0; i < formResponses.length; i++) {
   var formResponse = formResponses[i];
   var itemResponses = formResponse.getItemResponses();
   for (var j = 0; j < itemResponses.length; j++) {
     var itemResponse = itemResponses[j];
     Logger.log('Response #%s to the question "%s" was "%s"',
         (i + 1).toString(),
         itemResponse.getItem().getTitle(),
         itemResponse.getResponse());
   }
 }

UPDATE:

function onSubmit(e) {
  /* Get values entered by filling the form */
  var itemResponses = e.response.getItemResponses();
  var myWantedValue = itemResponses[COLUMN_NUMBER].getResponse();
}

Note: By passing the e(vent) as parameter the values can be accessed by submitting the live form, NOT by the script editor!

This code gives you the values for the last form response, is that what you're looking for ?

function myFunction() {
  var formResponses = FormApp.getActiveForm().getResponses();
  Logger.log(formResponses.length);
  var formResponse = formResponses[formResponses.length-1];
  var itemResponses = formResponse.getItemResponses();
  for (var j = 0; j < itemResponses.length; j++) {
    var itemResponse = itemResponses[j];
    Logger.log('Last response to the question "%s" was "%s"',
               itemResponse.getItem().getTitle(),
               itemResponse.getResponse());
  }
}
