Google Form. Confirmation Email Script. With edit url

Question

I have two working trigger functions in Google Script that fire when a form response spreadsheet gets a new submission. One inserts the "edit your submission" url into the spreadsheet. The other looks up the response's email and sends them a confirmation.

What I'm having a hard time understanding is how to populate the url first , and then send an email containing that url.

( Google Script is different to debug than js in the browser :\\ )

Setup triggers

function Initialize() {

        var triggers = ScriptApp.getScriptTriggers();

        for (var i in triggers) {
            ScriptApp.deleteTrigger(triggers[i]);
        }

        ScriptApp.newTrigger("SendConfirmationMail")
            .forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
            .onFormSubmit()
            .create();

           assignEditUrls();
    }

On form submit, searches for column titled "Clients Email", and sends a formatted email to them.

    function SendConfirmationMail(e) {

        try {

            var ss, cc, sendername, subject, columns;
            var message, value, textbody, sender;
            var url;

            // This is your email address and you will be in the CC
            cc = Session.getActiveUser().getEmail();

            // This will show up as the sender's name
            sendername = "XXXX";

            // Optional but change the following variable
            // to have a custom subject for Google Docs emails
            subject = "Form Complete: Mobile App - Client Questionnaire";



            // This is the body of the auto-reply
            message = "Confirmation text here.<br><br>Thanks!<br><br>";

            ss = SpreadsheetApp.getActiveSheet();
            columns = ss.getRange(1, 1, 1, ss.getLastColumn()).getValues()[0];

            // This is the submitter's email address
            sender = e.namedValues["Clients Email"].toString();

            // Only include form values that are not blank
            for ( var keys in columns ) {
                var key = columns[keys];
                if ( e.namedValues[key] ) {
                    message += key + ' :: '+ e.namedValues[key] + "<br />"; 
                }
            }

            textbody = message.replace("<br>", "\n\n");

            GmailApp.sendEmail(sender, subject, textbody, 
                                {cc: cc, name: sendername, htmlBody: message});

        } catch (e) {
            Logger.log(e.toString());
        }

    }

Separate function. Looks up form and applies the edit URL to the 26th column.

    function assignEditUrls() {
      var form = FormApp.openById('10BVYipGhDa_AthabHE-xxxxxx-hg');
        //enter form ID here

      var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Form Responses');

        //Change the sheet name as appropriate
      var data = sheet.getDataRange().getValues();
      var urlCol = 26; // column number where URL's should be populated; A = 1, B = 2 etc
      var responses = form.getResponses();
      var timestamps = [], urls = [], resultUrls = [];

      for (var i = 0; i < responses.length; i++) {
        timestamps.push(responses[i].getTimestamp().setMilliseconds(0));
        urls.push(responses[i].getEditResponseUrl());
      }
      for (var j = 1; j < data.length; j++) {

        resultUrls.push([data[j][0]?urls[timestamps.indexOf(data[j][0].setMilliseconds(0))]:'']);
      }
      sheet.getRange(2, urlCol, resultUrls.length).setValues(resultUrls);  
    }

Answer 1

Programmers are provided no direct control over the order that trigger functions will be invoked, when they are dependent on the same event.

In your situation though, there are a couple of options available.

1. Use only one trigger function for the event, and have it invoke the current functions in the order you require. (Alternatively, set assignEditUrls() up as the only trigger function, and have it call SendConfirmationMail() after completing its task.

2. Have SendConfirmationMail() check for the availability of the Edit URL, and call Utilities.sleep() if the URL isn't ready yet. (In a loop, until ready.)
