Add Events To Apple/Google/Yahoo/MicroSoft Calendars – atcb.js

Preview:

Description:

Add-to-Calendar Button is a JavaScript library that lets you add custom events to popular calendars (like Google Calendar, Yahoo Calendar, Outlook, Microsoft 365) and automatically generates iCal/ics files for other calendar services like Apple.

How to use it:

1. Add the Add-to-Calendar Button’s Stylesheet and JavaScript to the page.

<link rel="stylesheet" href="css/atcb.min.css" />
<script src="js/atcb.min.js"></script>

2. Insert your event data (JSON) into a hidden DIV container with the CSS class of atcb. That’s it.

<div class="atcb" style="display:none;">
  {
    "name":"Event Title",
    "startDate":"2022-02-24",
    "endDate":"2022-02-28",
    "options":[
      // add/remove calendars here
      "Apple",
      "Google",
      "iCal",
      "Microsoft365",
      "Outlook.com",
      "Yahoo"
    ],
  }
</div>

3. You can also define your event data in JSON-LD format.

<div class="atcb">
  <script type="application/ld+json">
    {
      "event": {
        "@context":"https://schema.org",
        "@type":"Event",
        "name":"Event Title",
        "description":"Event Description",
        "startDate":"2022-02-24T10:24",
        "endDate":"2022-02-28T18:56",
        "location":"Your Location"
      },
      "label":"Add to Calendar",
      "options":[
        "Apple",
        "Google",
        "iCal",
        "Microsoft365",
        "Outlook.com",
        "Yahoo"
      ],
    }
  </script>
</div>

4. Trigger the Add-to-Calendar menu on click instead.

<div class="atcb" style="display:none;">
  {
    "name":"Event Title",
    "startDate":"2022-02-24",
    "endDate":"2022-02-28",
    "options":[
      // add/remove calendars here
      "Apple",
      "Google",
      "iCal",
      "Microsoft365",
      "Outlook.com",
      "Yahoo"
    ],
    "trigger":"click",
  }
</div>

5. Add more detailed information to your event.

<div class="atcb" style="display:none;">
  {
    "name":"Event Title",
    "startDate":"2022-02-24",
    "endDate":"2022-02-28",
    "options":[
      // add/remove calendars here
      "Apple",
      "Google",
      "iCal",
      "Microsoft365",
      "Outlook.com",
      "Yahoo"
    ],
    "startTime":"10:24",
    "endTime":"18:56",
    "location":"Your Location",
    "label":"Text Displayed In The Button",
  }
</div>

6. The library also works with timezone:

<div class="atcb" style="display:none;">
  {
    "name":"Event Title",
    "startDate":"2022-02-24",
    "endDate":"2022-02-28",
    "options":[
      // add/remove calendars here
      "Apple",
      "Google",
      "iCal",
      "Microsoft365",
      "Outlook.com",
      "Yahoo"
    ],
    "timeZone":"Europe/Berlin",
    "timeZoneOffset":"+01:00",
  }
</div>

7. Customize the iCal/ics file name.

<div class="atcb" style="display:none;">
  {
    "name":"Event Title",
    "startDate":"2022-02-24",
    "endDate":"2022-02-28",
    "options":[
      // add/remove calendars here
      "Apple",
      "Google",
      "iCal",
      "Microsoft365",
      "Outlook.com",
      "Yahoo"
    ],
    "iCalFileName":"MY-Event"
  }
</div>
