Question

I am using html5 validation for my form in jsp page. I have given novalidate in form. When i click on submit button of that form it should validate the form now and display all validation in one label which was hidden before.How can i get these in jsp?
This is my form code.

<form action="#join1_form" method="POST">
  <div>
    <input type="text" name="firstname" id="firstname" value="" required placeholder="First Name" pattern="\w+" />
    <input type="text" name="lastname" id="lastname" value="" required placeholder="Last Name" pattern="\w+" />
  </div>
  <div>
    <input type="email" name="email" placeholder="Your Email" id="email" value="" required />
  </div>
  <div>
    <input name="password" id="password" type="password" required placeholder="New Password" pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z])\w{6,}" name="password" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Password must contain at least 6 characters, including UPPER/lowercase and numbers' : '');
if(this.checkValidity()) form.cpassword.pattern = this.value;">
  </div>
  <div>
    <input name="cpassword" id="cpassword" type="password" placeholder="Re-enter Password" required pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z])\w{6,}" name="cpassword" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');">
  </div>
  <div>
    <input type="label" hidden value="">
  </div>
  <input type="submit" value="Next">
</form>

try{
  String q="SELECT * FROM userdetails where email=?";
  ps=conn.prepareStatement(q);
  ps.setString(1,email1);
  rs=ps.executeQuery();

<html:form action="storenotes" onsubmit="return demo()">

call demo() function in your JavaScript
and submit form by
return true
or
return false
