I'm a newbie so excuse me if question could be stupid
I have a webpage where i have placed a form html with recaptcha validation
I have grabbed on the net following code :

Code:
<script type="text/javascript">
function validateCaptcha()
{
    challengeField = $("input#recaptcha_challenge_field").val();
    responseField = $("input#recaptcha_response_field").val();
    //alert(challengeField);
    //alert(responseField);
    //return false;
    var html = $.ajax({
    type: "POST",
    url: "http://mysite.com/script.php",
    data: "recaptcha_challenge_field=" + challengeField + "&recaptcha_response_field=" + responseField,
    async: false
    }).responseText;
    
    if (html.replace(/^\s+|\s+$/, '') == "success")

    {
		
        $("#show").html("Success. Submitting form.");
		
        return false;
        // Uncomment the following line in your application
        //return true;
    }
    else
    {
        $("#show").html("Your captcha is incorrect. Please try again");
        Recaptcha.reload();
        return false;
    }
}
</script>
and form html:

Code:
<form action="#"  method="post" onSubmit="return validateCaptcha()">

<p><?php echo recaptcha_get_html($publickey);?></p>
    <p style="color: red;" id="show">&nbsp;</p>
    <input type="submit" name="Submit" value="Submit">

</form>
On the file: script.php i have placed php code:

PHP Code:
<?php
require_once('controllers/recaptchalib.php');

$privatekey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

# was there a reCAPTCHA response?
 {
    $response = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);

if (!$response->is_valid) {
  echo 'ERROR: The recaptcha code was not entered correctly or expired.';
  die;

  
    
}

else   
echo "success";
 }


?>
the code work but i don't want display in my webpage only messages:
"Your captcha is incorrect. Please try again" if code is incorrect and
"Success. Submitting form." if code is correct.
But if the code is correct i want display under sentence "Success. Submitting form." the content of script.php ie print a table or whatever script contain obviously without reloading webpage or redirect to another page
How to?
thanks
