This does work on my system.

<script>
    $(document).ready(function() {
        $('#content').keyup(function() {
            var code = $('#content').val();
            $('#code-preview').html(code);
        });
    });

</script>

<textarea cols="10" id="content"></textarea>
<pre id="code-preview"></pre>
