Hello experts:
My form keeps ignoring the preventDefault JS event.
I built an html form with JS backend connected. The form is supposed to write to a Firebase db. The db is already active and works with an Android app. Permissions for testing are set to true for write and read.
I built the JS file incrementally testing code with the console log along the way. It worked perfectly till the Firebase script was added. Now it ignores the event to preventDefault.
The console lists no exceptions.

Open in new window

The JS code:
  // Create Reference Collection
  var testvaluesRef = firebase.database().ref('testvalues');

// Listen for form submit
document.getElementById('contactForm').addEventListener('submit', submitForm);

// Submit form
function submitForm(e){


 // Get values
  var name = getInputVal('name');
  var email = getInputVal('email');
  var phone = getInputVal('phone');
  var allvalues = name + ", " + email + ", " + phone;

  // Save values to Firebase
 saveTestValues(name, email, phone);

// Function to get get form values
function getInputVal(id){
  return document.getElementById(id).value;

// Save values to firebase
function saveTestValues(name, email, phone){
  var newtestvaluesRef = testvaluesRef.push();
    name: name,

One of those things that will really irritate you....
You're missing an end tag around the second firebase script.  So your main.js is never actually loading.


Thanks. I can't believe how many times I looked at that and missed it.
