<script type="text/javascript">

                function resetForm() {
                    <?php

                        unset($_SESSION['userList']);

                    ?>

                }
            </script>

Really appreciate for any help.

JAVASCRIPT

$.ajax({
    type: "POST",
    url: "phppage.php",
    data: "action=unsetsession",
    success: function(msg){
        alert(msg);
        if(msg == "success"){
            //cleared session
        }else{
            //failed
        }
    },
    error: function(msg){
        alert('Error: cannot load page.');
    }
});

PHP

if($_POST['action'] == "unsetsession"){
    unset($_SESSION['userList']);
    echo "success";
}
