[jQuery] Stop datepicker onDayLinkClick refreshing page

[jQuery] Stop datepicker onDayLinkClick refreshing page


I have a simple function:
onDayLinkClick: function(date) {
$('#id_from_date').val(date.asString());
return false;
It puts the value in the field but then refreshes the page. Using
Firebug it seems to be somewhere deep in Datepicker. Is there a way
of stopping this? Tried return true and does the same thing.
