How to schedule
and limit your google forms
Google
Forms impose
no limits. Any poll or survey created inside Google Forms has no expiration
date and it can collect unlimited number of responses until the form owner
decides to manually close* the form. But you can schedule these from and
close it by trigger. Suppose anyone wants to set their form before 5 days and
think after 5 days it will open for general user. For this situation you need
to apply trigger on script editor by using some lines of Google Script.
Setting Expiration date and time of form:
Google script editor give flexibilty to set
your expiration date and limiting your forms as following.
1.Go to google drive and click on existing
or create new form
2.Inside editor click on Tools->Script
editor.
3.Click on Form
4.Set DATE_OPEN =
"2014-01-04 06:00". On this time your form will be visible.
5.Set DATE_CLOSE = "2014-03-2 11:59". After this dste
snd time your form will be invisible.
6.Set MAX_RESPONE =
"200". This will set your maximum number of response.
7.(CNTL+S) save your script.

DATE_OPEN = "2014-01-04 06:00"
DATE_CLOSE =
"2014-03-2 11:59"
MAX_RESPONE = "200"
/* Initialize the form, setup time based triggers */
function Initialize() {
deleteTriggers_();
if (DATE_OPEN !==
"") {
closeForm();
ScriptApp.newTrigger("openForm")
.timeBased()
.at(parseDate_(DATE_OPEN))
.create();
}
if (DATE_CLOSE!==
"") {
ScriptApp.newTrigger("closeForm")
.timeBased()
.at(parseDate_(FORM_CLOSE_DATE))
.create();
}
if (MAX_RESPONE !==
"") {
ScriptApp.newTrigger("checkLimit")
.forForm(FormApp.getActiveForm())
.onFormSubmit()
.create();
}
}
/* Delete all existing Script Triggers */
function deleteTriggers_() {
var triggers =
ScriptApp.getScriptTriggers();
for (var i in
triggers) {
ScriptApp.deleteTrigger(triggers[i]);
}
}
/* Send a mail to the form owner when the form status changes
*/
function informUser_(subject) {
var formURL =
FormApp.getActiveForm().getPublishedUrl();
MailApp.sendEmail(Session.getActiveUser().getEmail(), subject,
formURL);
}
/* Allow Google Form to Accept Responses */
function openForm() {
var form =
FormApp.getActiveForm();
form.setAcceptingResponses(true);
informUser_("Your Google Form is now accepting responses");
}
/* Close the Google Form, Stop Accepting Reponses */
function closeForm() {
var form =
FormApp.getActiveForm();
form.setAcceptingResponses(false);
deleteTriggers_();
informUser_("Your Google Form is no longer accepting
responses");
}
/* If Total # of Form Responses >= Limit, Close Form */
function checkLimit() {
if
(FormApp.getActiveForm().getResponses().length >= MAX_RESPONE ) {
closeForm();
}
}
/* Parse the Date for creating Time-Based Triggers */
function parseDate_(d) {
return new
Date(d.substr(0,4), d.substr(5,2)-1,
d.substr(8,2), d.substr(11,2), d.substr(14,2));
}
