Datepicker: onMonthChange event

[majulvez]

Hi,

i've seen in the original js component (https://www.primefaces.org/primeng/#/calendar) the event 'onMonthChange'.

How can I use the event onMonthChange in the new jsf primefaces datepicker?

Thanks
Best regards

I think you will have to request it on Github. I don't see any "on" method for client side JS callbacks.

I was thinking in use the javascript options of the componet.

For instance, in calendar I can use this code in order to register a new function for an event which hasn't callback

PF('widgetNameCalendar').jqEl.datetimepicker('option', 'onClose', function(){console.log('closed')})

I tried

PF('widgetNameDatePicker').jqEl.datePicker('option', 'onMonthChange', function(){console.log('month changed')})

but I get this javascript error

Uncaught Error: cannot call methods on datePicker prior to initialization; attempted to call method 'option'

Best regards

Yep the DatePicker is a completely new JS component written from the ground up. The Calendar component is based on JQuery UI DatePicker widget. I think you will have to request this enhancement here: https://github.com/primefaces/primefaces/issues

onMonthChange event and onYearChange event is also triggering the normal html (change) event.
but the date value also not changed..

Better to do an event.prevent default before emitting this event
