How to send geolocation along with inputs when submiting HTML form in Google Apps Script

问题

I have a HTML form made with Google Apps Script that sends the data imputed into a Google Sheet. Here are the files in the project:

Code.gs

function doGet(request) {
  return HtmlService.createTemplateFromFile('Index').evaluate();
}

/* @Include JavaScript and CSS Files */
function include(filename) {
  return HtmlService.createHtmlOutputFromFile(filename)
      .getContent();
}



/* @Process Form */
function processForm(formObject) {
  var url = "URL OF GOOGLE SHEET";
  var ss = SpreadsheetApp.openByUrl(url);
  var ws = ss.getSheetByName("Data");

  ws.appendRow([formObject.local,
                formObject.direcao,
                formObject.carro,
                formObject.quilometragem,
                formObject.observacao,
                Utilities.formatDate(new Date(), "GMT-3", "dd/MM/yyyy HH:mm:ss")
               ]);
}

Index.html

<!DOCTYPE html>
<html>

 <script type="text/javascript">
 function showPosition() {
        navigator.geolocation.getCurrentPosition(showMap);
    }

function showMap(position) {
        // Get location data
       var latlong = position.coords.latitude + ", " + position.coords.longitude;
    }
 </script>

            </div>      
        </div>
    </body>
</html>

JavaScript.html

<script>
  // Prevent forms from submitting.
  function preventFormSubmit() {
    var forms = document.querySelectorAll('form');
    for (var i = 0; i < forms.length; i++) {
      forms[i].addEventListener('submit', function(event) {
      event.preventDefault();
      });
    }
  }
  window.addEventListener('load', preventFormSubmit);    


  function handleFormSubmit(formObject) {
    google.script.run.processForm(formObject);
    document.getElementById("myForm").reset();
  }
</script>

Everything works fine. However, I'm trying to add the user geolocation to be submitted alongside the inputs in the form. I don't want the user to do anything, it needs to be submitted as the user clicks the submit button. I have tried everything, including adding the showPosition() and showMap() functions that you can find in the Index.html file. However, I don't know what to do with it, as it gets the geolocation but I don't know how to make get it to be submitted with the form. Any help is appreciated.

Thanks in advance!

Here you go -

Code.gs

Just added the formObject.lat & formObject.long components to the processForm function.

function doGet(request) {
  return HtmlService.createTemplateFromFile('Index').evaluate();
}

/* @Include JavaScript and CSS Files */
function include(filename) {
  return HtmlService.createHtmlOutputFromFile(filename)
  .getContent();
}

/* @Process Form */
function processForm(formObject) {
  var url = "URL OF GOOGLE SHEET";
  var ss = SpreadsheetApp.openByUrl(url);
  var ws = ss.getSheetByName("Data");
  ws.appendRow(
    [
      formObject.local,
      formObject.direcao,
      formObject.carro,
      formObject.quilometragem,
      formObject.observacao,
      Utilities.formatDate(new Date(), "GMT-3", "dd/MM/yyyy HH:mm:ss"),
      formObject.lat,
      formObject.long
    ]
  );
}

Index.html

Did the following things here -

moved all script components to JavaScript.html
added 2 hidden input components to the form (lat & long)

            </div>
        </div>
    </div>
</body>

</html>

JavaScript.html

Modified the following things -

broke the showMap function to lat & long
added event listener to run showPosition on load
assigned values from showMap function to lat & long's corresponding html hidden form elements

<script>
    function showPosition() {
        navigator.geolocation.getCurrentPosition(showMap);
    }

    function showMap(position) {
        // Get location data
        var lat = position.coords.latitude;
        var geo1 = document.getElementById("lat");
        geo1.value = lat;
        var long = position.coords.longitude;
        var geo2 = document.getElementById("long");
        geo2.value = long;
    }

    // Prevent forms from submitting.
    function preventFormSubmit() {
        var forms = document.querySelectorAll('form');
        for (var i = 0; i < forms.length; i++) {
            forms[i].addEventListener('submit', function(event) {
                event.preventDefault();
            });
        }
    }
    window.addEventListener('load', preventFormSubmit);
    window.addEventListener('load', showPosition);

    function handleFormSubmit(formObject) {
        google.script.run.processForm(formObject);
        document.getElementById("myForm").reset();
    }
</script>

Tested this on my setup and it worked perfectly. Let me know in case you may require any further assistance too!
