Script running multiple times onFormSubmit

问题

I have the following code set to run based on a onFormSubmit trigger but it will sometimes run multiple times with the same submission. I want to verify if it already copied the row and if so to stop the script.

function toDo(){
  var responses = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
  var jobs = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Jobs");
  var lastrow = responses.getLastRow();
  var col = responses.getLastColumn();
  var row = responses.getRange(lastrow, 1, 1, 19).getValues();

  jobs.appendRow(row[0]);
  //copyValuesOnly(copyFromRange, copyToRangeStart);

  var si = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Jobs');

  var range = si.getRange("A2:R");

  range.sort({column: 5,ascending: true}),({column: 1, ascending:true});

}

this is a known problem with GAS + Forms. The way that you solve it is by creating a script lock that rejects (causing them to return early) all other attempts within a period of time.

function toDo(){
     SpreadsheetApp.flush();
     var lock = LockService.getScriptLock();
  try {
    lock.waitLock(5000); 
     } catch (e) {
        Logger.log('Could not obtain lock after 5seconds.');
        return HtmlService.createHtmlOutput("<b> Server Busy please try after some time <p>")
        // In case this a server side code called asynchronously you return a error code and display the appropriate message on the client side
        return "Error: Server busy try again later... Sorry :("
     }
  var responses = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
  var jobs = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Jobs");
  var lastrow = responses.getLastRow();
  var col = responses.getLastColumn();
  var row = responses.getRange(lastrow, 1, 1, 19).getValues();

  jobs.appendRow(row[0]);
  //copyValuesOnly(copyFromRange, copyToRangeStart);

  var si = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Jobs');

  var range = si.getRange("A2:R");

  range.sort({column: 5,ascending: true}),({column: 1, ascending:true});
  Utilities.sleep(5000);
  lock.releaseLock)();
}

I've had scripts that do this up to 8 times, and usually do it every 2-3 seconds. With this solution you are making a lock at the beginning and then sleeping at the end to make sure that the process time is greater than the wait time. (Here I used 5 seconds, that should prevent the double entry).

I have noticed that if you just make another copy of the sheet with the script, this error goes away. Seems to reset whatever was the issue in the original copy. Also try dis-abling the response receipts on your google forms.
