Below is the JS:
function sendEmail(event) {
  event.preventDefault();
  var $name = $('#name');
  var $email = $('#email');
  var $phone = $('#phone');
  var $message = $('#message');
  if (isNotEmpty($name) && isNotEmpty($email) && isNotEmpty($phone) && isNotEmpty($message)) {
    $.ajax({
      url: 'sendEmail.php',
      method: 'POST',
      dataType: 'json',
      data: {
        name: $name.val(),
        email: $email.val(),
        phone: $phone.val(),
        message: $message.val()
      }, success: function (response){
        console.log(response);
      }
    })
  }
}
The browser says sendEmail.php is not found.
jquery.min.js:2 POST http://localhost:3000/sendEmail.php 404 (Not Found)
This is the folder structure of my project:
The js code is from the file assets/mail/contact_form.js and the sendEmail.php is at the src folder.
