Change href location of the date and next/previous month in DatePicker

Change href location of the date and next/previous month in DatePicker


Currently I have a DatePicker widget that is show in a lightbox
window.
Whenever I click on a element (a date) my browser always scrolls to
the top of the page.
Because the href of each element is "#".
(the focus of the cursor is set to the first inputfield on the
lightbox)
Is there an easy way to change this to something like "javascript:;"?
What I don't understand, is that this also happens on next/previous
month where the onclick is the following:
DP_jQuery.datepicker._adjustDate('#pollwow_startdate', +1, 'M');
