How to only show input fields if checkbox is checked?

Question

Basically, I want to only show these fields if checkbox is selected, if it becomes unselected, disappear.

Answer 1

Matthews answer works great just that the .live deprecated in jQuery 1.7 use the .on

$('#supplied').on('change', function(){
    if ( $(this).is(':checked') ) {
        $('#date').show();
    } else {
        $('#date').hide();
    }
});
