Javascript to Add to Calendar

[Steve K Walker]

I would like to add a button to my form that will allow the user to click and have the event information sent to their iCal - or any other calendar they may be using.

I'm not a Javascript expert. Here is some code I found - but it doesn't work.
If there is anyone out there who can help it will be greatly appreciated.

var cal = ics();

  cal.addEvent('Demo Event', 'This is an all day event', 'Port Elizabeth', '10/10/2018', '10/10/2018');

  cal.addEvent('Demo Event', 'This is thirty minute event', 'Port Elizabeth', '10/10/2018 5:30 pm', '10/10/2018 6:00 pm');

<a href="javascript:cal.download()">Test</a>

Are you talking about a script in a PDF file or a web-page? If the former, it's not possible. If the latter, this is not the place for your question, as this forum is only about JS in PDF files...

I would like to add the Javascript to a Button in a PDF Form.
The button would be called ADD TO CALENDAR.

When clicked it would add the event details to the users calendar (iCal, etc).

Unless it can be done by opening a specific URL, it's not possible.
