    how does the script know when every input is validated and its time to stop preventing the default action of 'submit' ??

    • @chrischti
      @chrischti 2 года назад +9

      Don't use the prevent submit function in the java script, instead run the function from the form, by adding onsubmit="return validateForm()", by that the form will be submitted if the function returns true

      if (document.querySelectorAll('.success').length === 4) {
      // submit the form
      form.submit();
      }
      // You can submit the form if all the inputs are valid by adding a line of code after the validation checks inside the validateInputs function.
