Form Onsubmit Doesn't Call Javascript Function

I have checked recent blogs about onsubmit event not triggering the method. Those suggestions were not helpful for this problem.And i've tried this method and form in an another ht

Solution 1:

you almost done. simple quotes problem.you could change like this in your dom else statement

document.getElementById("firstNameLoc").innerHTML = '<img src="Resource/checked.png"/>Please Enter your First Name';

functionformValidation() {
  var fName = document.Log.firstName.value;
  var lName = document.Log.lastName.value;
  var pName = document.Log.penName.value;
  var email = document.Log.email.value;
  var password = document.Log.password.value;
  var confirmPassword = document.Log.confirmPassword.value;
  var status = false;
  if (fName.length < 1) {
    document.getElementById("firstNameLoc").innerHTML =
      "<img src='Resource/unchecked.gif'/>Please Enter your First Name";
    status = false;
  } else {
    document.getElementById("firstNameLoc").innerHTML = '<img src="Resource/checked.png"/>Done..!';
    status = true;
  }
  return status;
}
