Trigger an alert at a specific time on Google Script

问题

I'm very new to scripting so if anyone knows how to do this it'd be great help!

I have a user that logs in on business days at ~9 am, and has to do something before 9.30 am. To remind and insist that it's done I want to have an alert that says to do it, if a certain cell is not empty. Ideally it would check at 9, 9.10, 9.20 and 9.30, and pop up each time until it's done.

I tried to set up a trigger every 10 minutes, but I read that you can't use triggers with UI.

function startCustomTrigger()
{
  ScriptApp.newTrigger('alerta').timeBased().everyMinutes(10).create();
}

So I thought of making it an onEdit script when new date().getMinutes() is 0/10/20/30, and it worked, but then it keeps popping up when you continue working on the sheet for the whole minute. Adding new date().getSeconds() doesn't work because it's too short of a time window and easy to miss.

This is my current code:

function alerta() {
  var ss = SpreadsheetApp.getActiveSpreadsheet()
  var s = ss.getActiveSheet();
  var motosS = ss.getSheetByName("Motos - mañana");
  var motosRange = motosS.getRange(3, 1)
  var ui = SpreadsheetApp.getUi();
  var date = new Date();  
  var day = date.getDay();
  var hrs = date.getHours();
  var min = date.getMinutes()
  var sec = date.getSeconds()

  Logger.log(date)
  Logger.log(day)
  Logger.log(hrs)
  Logger.log(min)
  Logger.log(sec)

  if (motosRange == "" && (day >= 1) && (day <= 5) && (hrs = 9)){
      if (min == 0 || min == 14 || min == 20 || min == 30){
      var response = ui.alert('IMPRIMIR MOTOS PARA LA MAÑANA', 
                            "Hay que anotar el sector de las ventas de ayer e imprimir las motos para la mañana.", 
                            ui.ButtonSet.OK_CANCEL);
                         }
  }
  }

Use Script properties to store the alert status between function calls

Explanation

Script properties allow you to cache variables which are accessible by the subsequent script run
Create a property that is set to true if the alert has been shown already
Set the property back to false once one minute (or any other timespan you desire) has passed
The latter can be done with a time-driven trigger, or - easier - with Utilities.sleep().
The idea is that you check within the if statement the status of your boolean and do not show the alert again while the variable is true

Sample:

function alerta() {
  //initial setup
  if(!PropertiesService.getScriptProperties().getProperty("alreadyNotified")){
    PropertiesService.getScriptProperties().setProperty("alreadyNotified", false)
  }
  var ss = SpreadsheetApp.getActiveSpreadsheet()
  var s = ss.getActiveSheet();
  var motosS = ss.getSheetByName("Motos - mañana");
  var motosRange = motosS.getRange(3, 1).getValue()
  var ui = SpreadsheetApp.getUi();
  var date = new Date();  
  var day = date.getDay();
  var hrs = date.getHours();
  var min = date.getMinutes()
  var sec = date.getSeconds()

  Logger.log(date)
  Logger.log(day)
  Logger.log(hrs)
  Logger.log(min)
  Logger.log(sec)
  var alertStatus = PropertiesService.getScriptProperties().getProperty("alreadyNotified");
  //put "false" in quotes because Scriptproperties store the value as a string
  if (alertStatus == "false" && motosRange == "" && (day >= 1) && (day <= 5) && (hrs = 9)){
    if (min == 0 || min == 14 || min == 20 || min == 30){
      PropertiesService.getScriptProperties().setProperty("alreadyNotified", true);
      var response = ui.alert('IMPRIMIR MOTOS PARA LA MAÑANA', 
                              "Hay que anotar el sector de las ventas de ayer e imprimir las motos para la mañana.", 
                              ui.ButtonSet.OK_CANCEL);
      Utilities.sleep(60*1000);
      PropertiesService.getScriptProperties().setProperty("alreadyNotified", false);
    }
  }
}
