code that allows the datepicker() to focus first without showing the calendar UI until input field is clicked

datepickerNoFocus.js

function cwUtil_focusDateInput(name) {
    var selectedInput = $("[name='" + name + "']");
    $(selectedInput).focus();
    $(selectedInput).on("click", function() {
        $(this).datepicker();   
        $(this).focus();
    });
}
