How to write your modal window?

Question

Google Apps Script

I work with Google Spreadsheets and make an addition, it displays a Google disk modal window through a picker and selects a table whose sheets are added to a separate list for consolidation, but the problem is that the table does not want to be added to the list in any way? here is my spreadsheet https://docs.google.com/spreadsheets/d/1XzGtlhZ-AP...

files that are being parsed at the moment:
_file_picker.js.html picker description getsheetnames.gs model.window.html
$ code.gs no way I can’t find what the problem is, despite the fact that when I inserted a window with a Google drive into the sidebar itself, everything worked, but it doesn’t work with a modal,


As a result, I was told what needs to be done: it is necessary that after the side bar and modal, when calling Picker, a new custom modal appears and Picker is already on it. but it doesn't work for me

Answer 1

The main idea is to call a function on the server to open a new dialog

document
  .getElementById('btnShowModalDialog')
  .addEventListener('click', (e) => {
    e.preventDefault();
    google.script.run.showModalDialog();
  });

Working example
Note that after your dialog has finished you will need to store your data somewhere, and force the sidebar to retrieve that data.
