[jQuery] input type text toUpperCase() jquery question

[FrankTudor]

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">
