如何为Google Spreadsheet股票检查电子邮件编码

Question

现在我正在尝试设置一个可以帮助我的同事更新库存的功能。我需要一个程序，一旦股票更新完成，股票通知的电子邮件将发送给经理。

我试图在没有触发器的情况下运行该程序，我收到了一个完美的电子邮件，但现在我需要对程序应用触发器，所以当我的同事更新库存时，她不需要运行程序来发送电子邮件。

我只是想知道如何才能更好地触发电子邮件发送，而不是每次更新都会触发程序运行并发送多封电子邮件。另外请告诉我如何设置范围'e'以及如何设置触发器工作

由于

这是代码

 function onEdit(e) {
   //if (activeSheet.getName() !== "inventory") return;
   //var sheet = SpreadsheetApp.getActiveSheet();
   var sheet = e.source;
   var rows = sheet.getDataRange();
   var numRows = rows.getNumRows(); 
   var workRows = numRows -8;
   var dataRange = sheet.getRange(8,2, workRows, 13)
   // Fetch values for each row in the Range.
   var data = dataRange.getValues();

   //email information and content
   var emailAddress = 'xxx@gmail.com';  
   var bodyrefill = '';      
   var bodyset = '';
   var bodysend = '';
   var subject = '';
   var check1 = 0;
   var check2 = 0;

  /*
   var range = e.range;
   var columnOfCellEdited = range.getColumn();
   if (columnOfCellEdited==14){

     columnofCellEdited.setNote('Last modified: ' + new Date());

     }
     */

   for (var row in data){
     if(data[row][12]!=0){
       if (data[row][11]<=data[row][12]){
         check1 += 1;
         var num = data[row][12]-data[row][11];
         bodyrefill = bodyrefill + "The " + row + " line, " + data[row][2] + "          needs refill product for" + num + "\n";
       }
     }
     else{
       check2 += 1;
       bodyset = bodyset + "The " + row + " line, product " + data[row][2] + " needs to set up a product limit." + "\n";
     }
   }

   if (check1 > 0){
     if (check2 > 0){
       subject = "Google sheet has products need to refill and set up alart limit.";
       bodysend = bodyrefill + bodyset;
     }
     else{
       subject = "Google sheet has products need to refill.";
       bodysend = bodyrefill;
     }
   }
   else{
     subject = "Google sheet has products need to set up alart limit.";
     bodysend = bodyset;
   }
   MailApp.sendEmail(emailAddress, subject, bodysend);
   SpreadsheetApp.flush();

 }
