Weeknumber

Scheduler Javascript
#1

Hello,

Is it possible to display the weeknumber in the dhx_cal_date div?

You can redefine template for related area, and use any custom logic for text generation.
Unfortunately, current version of scheduler can’t calculate week number from the date automatically.

Hello,

Thanks for you reply, is it also possible to display the current date in another div outside the scheduler container? The same date that is displayed in the dhx_cal_date div?

Best Regards,

Hey guys,
i wrote this little function to calculate the calendar week. I´m using the definition of the ISO 8601, where the week with the 4.January of a year is the first calender week.

[code]function sm_calenderweek(date)
{
var year = date.getYear();
var fourthJan = new Date(year,00,04);
var calweek = date-fourthJan;
calweek= calweek/(2460601000);
if(fourthJan.getDay()!=0)calweek = calweek + fourthJan.getDay()-1;
else calweek = calweek+1;
calweek = (calweek /7 )+1;
calweek = Math.ceil(calweek);
if(calweek == 53)
{
fourthJan = new Date(year+1,00,04);
if((fourthJan-date)/(2460601000)<=4){
calweek=1;
}

}
return calweek;

[/code]

to show this in weekview u need to implement:

scheduler.templates.week_date=function(date){ var string = 'KW '+ sm_calenderweek(date) + ', ' + date.getYear(); return string; }
or something like that

Hello,

Hello,

I wrote my own function and this is working correctly:

function getIso8601Week(date) {
				var checkDate = new Date(date.getTime());
				checkDate.setDate(checkDate.getDate() + 4 - (checkDate.getDay() || 7));
				var time = checkDate.getTime();
				checkDate.setMonth(0);
				checkDate.setDate(1);
				return Math.floor(Math.round((time - checkDate) / 86400000) / 7) + 1;
			}
