重定向到同一页面后如何调用jquery函数？

Let's say after my user fills a form and clicks the submit button, I want the user redirected to the same page with the form and a jquery animation will play. The header function is there to prevent the user from refreshing the page and resubmitting the same data.

UPDATE: I've decided to use $_SESSION to record the user's session to try to get the jquery animation to play after they get redirected to the same page:

<?php
session_start(); 

if (isset ($_POST['submit']))
{
$connect = mysql_connect("","","") or die("Error connecting to db");
mysql_select_db("") or die("Error connecting to db");

$text = $_POST['text'];



mysql_query ("INSERT INTO header VALUES('','$text')");

  $_SESSION['jq']=='a';
    header('Location: header.php');
    die();

}


if($_SESSION['jq']=='a') {
   $_SESSION['jq']='';

echo'
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){

    $("div").hide(3000);

});
</script>';


}




?>



<html>
<head>

<style type="text/css">
#jquery {border:1px solid black;width:300px;}
</style>

</head>
<body>
<form name="header" action="header.php" method="post">


<input type="text" name="text" />
<input type="submit" name="submit" value="submit"    />
</form>
<div id="jquery">this is jquery animation</div>

</body>
</html>

    Use like this

    if (isset ($_POST['submit']))
{
    $text = $_POST['text'];
    mysql_query ("INSERT INTO header VALUES('','$text')");

    //redirect to same page that user submitted form from
    header('Location: form.php?jq=a');
    die();
}
if($_GET['jq']=='a') {
   //play animation
   echo'<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
   <script type="text/javascript">
   $(document).ready(function(){

       //insert jquery animation code

   });
   </script>';
}

    Or

    session_start();
if (isset ($_POST['submit']))
{
    $text = $_POST['text'];
    mysql_query ("INSERT INTO header VALUES('','$text')");

    //redirect to same page that user submitted form from
    //$_SESSION['jq']=='a'; commented for your understanding remove this in your code.
    $_SESSION['jq']='a';
    header('Location: form.php');
    die();
}
if($_SESSION['jq']=='a') {
   $_SESSION['jq']='';
   //play animation
   echo'<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
   <script type="text/javascript">
   $(document).ready(function(){

       //insert jquery animation code

   });
   </script>';
}
