Prevent Duplicate Form Submissions (jQuery)

Use the jQuery script below. Make sure you put the script after the closing <form> tag.

<script>

jQuery(function() {
$("form").submit(function() {
$(this).submit(function() {
return false;
});
return true;
});
});
jQuery('form').submit(function(){
$(this).find(':submit').attr( 'disabled','disabled' );
});
