Dynamically Displaying Questions in Google Forms Using Google Apps Script

Creating dynamic forms can significantly enhance user experience. In this guide, we will address a common issue many face with Google Forms - how to display a second question with a pre-filled answer based on the response to the first question. This process can be easily managed with Google Apps Script. Whether you're managing event registrations or surveys, this method allows you to validate inputs and streamline your form responses effectively. Let’s break down the solution into clear steps.

The Problem

You have a Google Form that includes the following:

Question 1: A code entered by users for identification purposes.

Question 2: A follow-up question that requires a pre-filled answer if Question 1 is answered correctly.

To achieve this functionality, you need to address several questions:

How can you retrieve the response code provided by the user?

How to validate this code dynamically with a list maintained in an Excel sheet?

How to display Question 2 pre-filled based on the validation of Question 1?

The Solution

With Google Apps Script, you can create a seamless experience for users by dynamically validating and displaying form elements. Here’s how to accomplish it:

Step 1: Get User Response for Question 1

First, you will need to capture the user's input. To do this, you can use the onFormSubmit trigger to capture the response when the user submits the form.

This function checks if the input code is present in your predefined list.

Step 3: Display Question 2 Pre-filled

After validating the code, if it's correct, you can pre-fill Question 2. You can create a web application linked to your form that opens only if the validation is successful. Here is how to set this up:

This code redirects the user to the Google Form with Question 2 pre-filled based on their validated input.

Conclusion

Using Google Apps Script, you can create an interactive and dynamic Google Form that responds based on user inputs. By following the steps above, you can successfully validate responses and show the user customized content accordingly. This technique is powerful for anyone looking to enhance engagement through their forms.

Implement these steps in your Google Forms, and watch how user responses become streamlined and efficient. Happy scripting!
