Prevent form submit but retain form validation

Question

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?

Answer 1

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>

Answer 2

I use checkValidity() and reportValidity() to solve this problem.

Assume your form has id as FORM_ID

Sample code:

function handleSubmit (e) {   e.preventDefault();    var ele = document.getElementById("FORM_ID");   var chk_status = ele.checkValidity();   ele.reportValidity();   if (chk_status) {     ...     // do your customized submit operations here.     } }
