Script for Google Forms.
"Fixes" other... field in checkbox and radio groups.
Whenever form is submitted and "other" option is selected,
input goes to corresponding checkbox/radio group in form
as a new option, so next respondents don't have to put it
in manually.
To use copy-paste code to your forms project and assign
onSubmit function to project's "on form submit" trigger.
By default applies to all checkbox/radio groups in the
form, specify required IDs in applyOnlyTo if needed.
Normally it is in "data-item-id" field and numeric only.
E.g. data-item-id="193574675"
function onSubmit(event) {
var applyOnlyTo = []; // fill this in if you want descibed behaviour only for selected checkbox/radio groups;
var form = event.source;
var response= event.response;
var choosers;
if (applyOnlyTo.length > 0) {
choosers = {
return form.getItemById(id);
} else {
var checkboxes = form.getItems(FormApp.ItemType.CHECKBOX);
var radios = form.getItems(FormApp.ItemType.MULTIPLE_CHOICE);
choosers = checkboxes.concat(radios);
choosers.filter(function(c) {
var type = c.getType();
return (type == FormApp.ItemType.CHECKBOX) ? c.asCheckboxItem().hasOtherOption():
(type == FormApp.ItemType.MULTIPLE_CHOICE) ? c.asMultipleChoiceItem().hasOtherOption():
for (var i = 0; i < choosers.length; i++) {
var chooser = choosers[i];
chooser = (chooser.getType() == FormApp.ItemType.CHECKBOX) ? chooser.asCheckboxItem():
(chooser.getType() == FormApp.ItemType.MULTIPLE_CHOICE) ? chooser.asMultipleChoiceItem():
"Something went wrong. It is definitely Google's fault!";
var chooserResponse = response.getResponseForItem(choosers[i]);
if (chooserResponse == null) continue;
chooserResponse = chooserResponse.getResponse();
var otherField = (chooser.getType() == FormApp.ItemType.CHECKBOX)?
var choices = chooser.getChoices();
if (!mContains(choices, otherField)) {
var newChoice = chooser.createChoice(otherField);
function mContains(choices, item) {
for (var i = 0; i < choices.length; i++) {
if (choices[i].getValue() == item) {return true;}
return false;
