如何在不反复设置触发器和身份验证的情况下重用 App 脚本？

Question

Update: I'm sorry I didn't post the code originally. In my newbie-ness, I didn't think it honestly mattered, but I've been around long enough to know better. See below:

function openForm(e)
{
  populateQuestions();
}

function populateQuestions() {
  var form = FormApp.getActiveForm();
  var googleSheetsQuestions = getQuestionValues();
  var itemsArray = form.getItems();
  itemsArray.forEach(function(item){
    googleSheetsQuestions[0].forEach(function(header_value, header_index) {
      if(header_value == item.getTitle())
      {
        var choiceArray = [];
        for(j = 1; j < googleSheetsQuestions.length; j++)
        {
          (googleSheetsQuestions[j][header_index] != '') ? choiceArray.push(googleSheetsQuestions[j][header_index]) : null;
        }
        item.asCheckboxItem().setChoiceValues(choiceArray);
        // If using Dropdown Questions use line below instead of line above.
        //item.asListItem().setChoiceValues(choiceArray);
      }
    });     
  });
}

function getQuestionValues() {
  var ss= SpreadsheetApp.openById('1QeckPxMYSYGMkZ-QggY76u03N1qBKBGL2UEMcUvu7sM');
  var questionSheet = ss.getSheetByName('Sheet5');
  var returnData = questionSheet.getDataRange().getValues();
  return returnData;
}

After months of work, I finally have cracked the script to getting what I wanted. Now I need to use this script over and over in multiple Google Forms (forms, for short). By copy and pasting the Form within Drive, I carry the App Script with each copy, but not the trigger or the authorization needed to run it. I need assistance in learning how I can make this process quicker.

I have very limited knowledge of add-ons and things, but I'm willing to learn. I do not necessarily need this to be a public access Script, just want to make my life less repetitious.

I would also like to make it so after installing the add-on, users can just pick the Sheet/Tab through a UI and not editing the code specifically, but that's a different story.

For the moment, You can create an installable trigger so you don't have to add the trigger manually anymore. You should use this:

function createFormOpenTrigger() {
  const gf = FormApp.getActiveForm()
  ScriptApp.newTrigger('populateQuestions')
      .forForm(gf)
      .onOpen()
      .create();
}

Instead of:

function openForm(e)
{
  populateQuestions();
}

As for the credentials, deploying the script as an add-on I will help you with the OAuth part. However, I was unable to test it today due to propagation. I'm still getting a message that the Apps Script is not bound to the GCP project. I will try my luck tomorrow, in the meantime you can read the following documentation about it. Here .

Sorry, I took some time to post the answer since you mentioned that you didn't know how to create an add-on, so I tried to add step by step information.

Update:

You can add this part at the top of the code, this will create a menu that will allow you to run the script for the first time in the Google Form after we make it an Add-on.

function onOpen() {
  //you can change the names of the menu, just not change
  // this part "createFormOpenTrigger"
  FormApp.getUi()
    .createMenu('formTest')
    .addItem('Run Apps Script', 'createFormOpenTrigger')
    .addToUi();
}

If you do not have a GCP project, you can created one by following the steps here , or following the steps:

1. Open the Google API Console projects list .
2. Click Create Project .
3. Fill out the project information for your add-on.
4. Click Create .

Copy the Project number , and add it to the Apps Script to switch to a different standard Cloud project .

1. 
2. 

Deploy the Apps Script as an Add-on.

1. 
2. 
3. 

Remember the version number you will need later on. Access to the Google Cloud Project link with the Apps Script.

Setup the OAuth consent screen , select internal to make sure that only you have access to it (and users of your Workspace if you have one)

We will need to the Add-on listing , so we will need to add "Google Workspace Marketplace SDK" in the Library .

1. 
2. 
3. 

Add the App configuration information, add all the require information there, the only recommendation I can provide you are these 2:

1. 

2. 

   Note: this can be found under "Project Settings"

Lastly, fill out the information under "Store listing".

Note: You can add dummy information if only you are going to use the add-on.

Once all that is done, use the "App URL" link to install the add-on. When you open a Google Form it will show up under the Add-on list:

And you will see the option to Run the Apps Script, thanks to the last part of the code we added.

Click on it, and it might ask you for permission the very first time you use it. But it will not request it again even if you add it to a new form.
