Og her kommer den så i java script:
Pass-thru til det felt (her dato) på formen der skal skrives til:
<a href="java script:show_calendar2('document.forms(0).dato', document.forms(0).dato.value);"><img src="datepicker.gif" width="16" height="16" border="0" alt="Click Here to Pick up the date"></a>
- der skal så ligge en datepicker.gif i image resources. (Eller også skal den bare laves som button, whatever...)
Så er det bare at tilføje flg. i JS Header :
function show_calendar2(str_target, str_datetime) {
var arr_months = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"];
var week_days = ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa"];
var n_weekstart = 1; // day week starts from (normally 0 or 1)
var dt_datetime = (str_datetime == null || str_datetime =="" ? new Date() : str2dt2(str_datetime));
var dt_prev_month = new Date(dt_datetime);
dt_prev_month.setMonth(dt_datetime.getMonth()-1);
if (dt_datetime.getMonth()%12 != (dt_prev_month.getMonth()+1)%12) {
dt_prev_month.setMonth(dt_datetime.getMonth());
dt_prev_month.setDate(0);
}
var dt_next_month = new Date(dt_datetime);
dt_next_month.setMonth(dt_datetime.getMonth()+1);
if ((dt_datetime.getMonth() + 1)%12 != dt_next_month.getMonth()%12)
dt_next_month.setDate(0);
var dt_firstday = new Date(dt_datetime);
dt_firstday.setDate(1);
dt_firstday.setDate(1-(7+dt_firstday.getDay()-n_weekstart)%7);
var dt_lastday = new Date(dt_next_month);
dt_lastday.setDate(0);
