[jQuery] input type text toUpperCase() jquery question


As a user types in content to this this text field I would like tho
force the text to uppercase to as keys are pressed.
How would this be done?
and is toUpperCase a real jquery function? if not wbhat would be a
simple way to hndle this with either CSS or someother method...
Here is what I have and obviously I am stuck...
<script type="text/javascript">
    $(document).ready(function()
        {
            $('.highball').keypress( function()
                {
                    $('.highball').toUpperCase()
                }
            );
        }
    );
</script>
<input type="text" style="" class="ac_input highball"
autocomplete="off" id="CityLocal" value="" type="text">
