When updating from 3.6 to 3.7 I've run into a problem that I think it's related to this issue. I wasn't sure if I should start a new thread since it's related, so please forgive me.

I have a custom backend component where I give the users the option to add multiple date fields. These date fields are generated dynamically with javascript. On each of these fields I initialize a datepicker. It was working great until the 3.7 update. I kept on getting the Calendar is not defined error. Coming on this thread helped me figure out that problem as that error is no longer appearing. However, when I click on the button to open up the calendar I get the following error: Calendar is not a constructor. I've looked at the documentation but I can't find anything that indicates any changes to the calendar.js setup function. On this form I also have another jform datefield and that one does work. So I compared previous version to this 3.7 version and I can see on the old one the source code where the datepicker is being initialized and it's the exact same way as I'm doing it. However, after the 3.7 update I can't find anywhere on the source code where Joomla is initializing the datepicker for the jform field. I was hoping I could find it to use it as an example.

Another thing that I don't understand is why the jform datefield was working even before I added the fix document on this thread, but yet my fields were not.

Here is my code that I'm using:

      $("input[name^='jform[date]']").each(function(index){
        Calendar.setup({
          inputField: $(this).attr('id'),
          ifFormat: '%m/%d/%Y',
          button: $(this).attr('id') + '_img',
          align: 'Tl',
          singleClick: true,
          firstDay: 0
        });
      });

Thank you

Instead of Calendar.setup() you will need to use now JoomlaCalendar.init()

The new code should be something like

• please make any corrections needed yourself and / or ask in Joomla forums as i will not answer here any more, i am posting this for anyone else also reading this issue

$("input[name^='jform[date]']").each(function(index){

	var theInput = $(this).attr('id');
	var container_id = 'box_' + theInput.attr('id');

	//theInput.closest('.someclassname').attr('id', container_id);
	//theInput.closest('.field-calendar').attr('id', container_id);
	theInput.parent().parent().attr('id', container_id);

	JoomlaCalendar.init(document.getElementById(container_id));

});
