How can I use the setDates in Kartik DatePicker?
I use
$('#extCopyDatepicker').datepicker('setDates', myDate);
for the widget id I use
<?= DatePicker::widget([
'id' => 'extCopyDatepicker',
...
'multidate' => true,
...
But this gives me a error Uncaught TypeError: $(…).datepicker is not a function.
without the
$('#extCopyDatepicker').datepicker('setDates', myDate);
it runs fine.
