problem with jquery calculator

problem with jquery calculator

I want to automatically load my calculator on the screen on load. How do I do that?

I've allready tried this:
- first I set my focus to my input field like this:
 $('#driver').focus();

- second I say that my calculator must show on focus of the input:
$('#driver').calculator({showOn: 'focus',
     onClose: function(value, inst) {
                if (value.length > 3) {
                    $('#driver').val('');
                }
        },layout: ['_9_8_7', '_6_5_4', '_3_2_1', '_0@E@U']});

The problem is that the input gets the focus but the calculator won't show. When I minimise my webbrowser and re-open it then my calculator shows. Can anybody help me with this problem?

Kind regards
