This article illustrates how the submit button is not available after javascript implements a form submission. Share with you for your reference. The details are as follows:

When javascript is used here to control form submission, the submit button becomes unavailable, preventing the user from submitting multiple times.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title> The button is disabled after the form is submitted </title>
<script type="text/javascript">
function sub() {
  document.forms[0].elements[0].disabled = true;
  <form action="login.action" method="post">
    <input type="button" name="btn" value=" Submit the form "
 onclick="return sub();" />

I hope this article is helpful for you to design javascript program.
