Prevent form submit but retain form validation

问题:

How do I retain the default HTML form validation and yet prohibit form submitting? I have tried using event.preventDefault() and return false. Both are successful in stopping the form from submitting but both fail in form validation. I have also tried this solution, but even that does not work.

Is anybody able to help me?

Both event.preventDefault() and return false; work if used on form submit. The HTML 5 validation is still present.

jQuery("form").submit(function(e){
  e.preventDefault();  
  //or
  //return false;
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" method="post">
  <input id="name" type="text" required="required" />
  <input id="email" type="email" required="required" />
  <input type="submit" id="btnSubmit" />
</form>
