Adapt GAS script functions from a Spreadsheet to a Web Application

Question

I'm new to GAS and JavaScript in general, so I'd like some help adapting a script from a spreadsheet to a Web App .

Based on some scripts I found, I developed a code to work the way I need in a Google Spreadsheet , but after making it work exactly the way I need it, I realized that a Web App could be a better alternative, mainly because of how it works on Mobile.

The point is that I didn't have a very linear JavaScript learning curve, my learning was solving specific needs, so I have difficulty with some basic concepts... and to be quite honest, deeply understanding JavaScript is not my main focus, but this knowledge is missing me now...

Let's get straight to the point

My current spreadsheet is this one: Google Sheet - Stack Demonstration

In the GAS linked to this worksheet there are 2 .gs files and one HTML .

GAS files

1 - CSV.gs | Contains 2 scripts

CheckForFiles - Checks the amount of files in a given Google Drive folder before releasing the execution of other scripts.

SheetToCSV - Creates a .csv file of the sheet in the parent folder of that sheet. This script is applied to the spreadsheet's Submit button.

2 - Upload.gs | Contains some functions responsible for uploading files through the spreadsheet.

ShowDialog0101 - Basically it's a script to call the upload page through an HTML alert in the spreadsheet.

GetParent - Basically it's a script that discovers the ID of the spreadsheet's parent folder and passes this information to the HTML file. I created this function because that way I can use this worksheet's folder as a model folder, simply duplicating the entire content without having to edit the code to update the worksheet's folder ID.

CreateOrGetFolder - This is the main function of the upload script, it checks if there is a child folder that has the name "Video" inside the parent folder, if it exists, it takes the ID of that folder so that the file is uploaded in that folder, if it does not exist, it creates a folder called "Video" and takes the ID of the created folder.

This is the Web App that launches when the Video File button is clicked:

Web App - Stack Demonstration

HTML file

Basically contains the client-side upload functions, I adapted this script based on this one.

What i would like to do

As I commented initially, I would like to adapt these scripts to work in a Web App .

My idea is that instead of the person filling out the worksheet, they fill out a form.

For this I need to adapt mainly the SheetToCSV script to link with a Submit button in the Web App , the idea is that as soon as the form is completed and the file upload is completed, this button is released and then when clicking on it the SheetToCSV script be triggered by creating a .csv file in the spreadsheet's parent folder with all the form responses.

My main difficulty is in linking the .csv generation script with the Submit button, I've been racking my brains over this for days.

I'm already having nightmares with this programming, literally... if anyone can help me with this, I'd be very grateful!

EDIT

I'll try to explain in a little more detail here.

Currently, I have this google spreadsheet here:

This worksheet contains modified versions of 2 scripts created by Tanaike.

Script 1 - Generates a .csv file with the worksheet fields in the same folder as the worksheet.

Script 2 - It is a modified version of Tanaike's Resumable Upload for Web Apps script, it is called in the spreadsheet via html alert .

Resumable Upload for Web Apps via HTML Alert

CSV file generated by the worksheet

Everything works as expected in this worksheet, but now I would like to convert it to a Web App , like this example:

The issue is that I don't know how to convert Tanaike's .csv generation script to generate the files through this html form, what I need is to integrate it with the Submit button of the Web App and collect the form fields in a .csv file.

The Spreadsheet and the Web App can be viewed at these links:

Answer 1

Thank you for replying. Can I ask you about your expected values for the CSV data? In this case,

I confirmed your expected result in this question as follows.

• You want to retrieve 2 text values of "name01", "description", and 2 values from dropdown lists of "Option1" and "Option2". The total values are 4 values.
• When the HTML form is submitted, you want to create a new CSV file for every submission.

In this case, how about the following modification? Unfortunately, in your question, your script is not shown. So, in this answer, I would like to propose a simple modification.

When I saw your sample Spreadsheet including your script, when the submit button is clicked, it seems that the function submitForm() is run. In this answer, this is used.

Modified script:

Javascript side:

Please modify submitForm() as follows.

function submitForm() {

  // Added the below script.
  var name = $('#name01').val();
  var description = $('#description').val();
  var option1 = $('#Option1').val();
  var option2 = $('#Option2').val();
  var data = [name, description, option1, option2].join(",");
  google.script.run.saveDataAsCSV(data, uploadParentFolderId);

  if ($('#submit-btn.disabled')[0]) return; // short circuit

Google Apps Script side:

Please add the following function. Please modify the filename of "sample.csv" to your actual situation.

const saveDataAsCSV = (data, folderId) => DriveApp.getFolderById(folderId).createFile("sample.csv", data);

• By this modification, 4 values in HTML form are retrieved and save it as a CSV file to the folder of uploadParentFolderId .
• If you want to save the file to other folder, please modify uploadParentFolderId of google.script.run.saveDataAsCSV(data, uploadParentFolderId) .
