<form action="<?php echo Mage::getUrl('abc_checkout/cart/placeorder'); ?>" method="post" id="confirm_order_form" class="info-static" onsubmit="return submitOrder();">

    <div class="buttons-set">
    <p class="back-link"><span onclick="history.go(-1);
                    return true;" class="engine-btn">Back</span></a></p>
    <button type="submit" title="<?php echo $this->__('Place your order') ?>" class="engine-btn continue"><span><span><?php echo $this->__('Place your order') ?></span></span></button>
    <div class="mt30">
        <?php echo $this->__('Please be patient.'); ?>

I want to disable this submit button after one click on front end.

use jquery for disable button

 $(".engine-btn").click(function () {
   $(".engine-btn").attr("disabled", true);

on the <button> tag add "onclick"="jQuery(this).disabled = true;"


jQuery now has the .one() function that limits any given event (such as "submit") to one occurrence.

For Example:

$('#myForm').one('submit', function() {

I hope this will help you.
