Using Javascript can you get the value from a session attribute set by servlet in the HTML page

I have a servlet that forwards to a HTML page, using redirect. Because I am using ajax and php on the html page to do other functions. Can turn into a jsp. Is there a way I can get the name -"poNumber" I get in servlet in the session attributes. I was to get it and display it's value.

I am new to programming.

Can get this working in jsp.

However need to get this working in a html page. Can I do it with javascript?

I have tried:

      <script type="text/javascript">
      var purchaseOrderNo = session.getAttribrute("pONumb");
      document.write("pONumb");
      </script> [

This does not output any values on the HTML page.

Tried:

       <script type="text/javascript">
       var purchaseOrderNo = (String) session.getAttribrute("pONumb");
           document.write("pONumb");
           </script>

Again get no output on page.

Tried:

            <script type="text/javascript">
            String purchaseOrderNo = (String) session.getAttribrute("pONumb");
            document.write("pONumb");
            </script>

Again get no output on page?

Can not think of any thing else to try. The servlet that redirects to this HTML page creates and set session attribute pONumb.

<?php 
    $sessionDetails = $this->Session->read('Auth.User');

    if (!empty($sessionDetails)) {


        $loginFlag = 1;
        # code...
    }else{
        $loginFlag =  0;
    }


?>

<script type="text/javascript">

    var sessionValue = '<?php echo $loginFlag; ?>';
    if (sessionValue = 0) {

        //model show
    }
</script>
