jquery - Filtering FullCalendar events with checkboxes (client-side with javascript) - Stack Overflow

I have a well working fullcalendar script that adds css-classes to events according to data attributes via eventRender. I now need to filter these specific attributes with checkboxes, but I have no idea at all how I should get this going!

My script looks as follows:

<script>
    $(document).ready(function() {
        $('#calendar').fullCalendar({
            eventRender: function(calEvent, element, view) {
                if (calEvent.risk == "normal") {
                    element.css('background-color', '#99FF99');
                }
                if (calEvent.risk == "event") {
                    element.css('background-color', '#415eec');
                }
                if (calEvent.risk == "whisper") {
                    element.css('background-color', '#D7CDD5');
                }
            },
            allDaySlot: true,
            displayEventTime: true,
            displayEventEnd: true,
            editable: false,
            firstDay: 1,
            weekNumbers: true,
            selectable: false,
            weekNumberCalculation: "ISO",
            eventLimit: true, 
            events: 'parts/events22.php'
        });
    });
</script>

The html checkboxes:

<div class="checkbox">
  <label><input type="checkbox" value="normal">Normal</label>
</div>
<div class="checkbox">
  <label><input type="checkbox" value="event">Event</label>
</div>
<div class="checkbox">
  <label><input type="checkbox" value="whisper">Whisper</label>
</div>

Does someone know how I can connect the checkbox-values to calEvent.risk, i.e. specific data attributes so as to filter them? Or does someone have a different idea for multiselect filtering with fullcalendar? I'd be really grateful for any help!

Set a change handler on checkboxes to rerender events. eventRender returning false keeps it from displaying, so make a filter function to get the checked values and return if the event.risk is in those values

    $(document).ready(function() {
      $('#calendar').fullCalendar({
        eventRender: function(calEvent, element, view) {
          if (calEvent.risk == "normal") {
            element.css('background-color', '#99FF99');
          }
          if (calEvent.risk == "event") {
            element.css('background-color', '#415eec');
          }
          if (calEvent.risk == "whisper") {
            element.css('background-color', '#D7CDD5');
          }
          return filter(calEvent); // Only show if appropriate checkbox is checked
        },
        allDaySlot: true,
        displayEventTime: true,
        displayEventEnd: true,
        editable: false,
        firstDay: 1,
        weekNumbers: true,
        selectable: false,
        weekNumberCalculation: "ISO",
        eventLimit: true,
        events: 'parts/events22.php',
        events: [{
          start: moment().add(1, 'day'),
          title: 'Normal',
          risk: 'normal'
        }, {
          start: moment().add(2, 'day'),
          title: 'Event',
          risk: 'event'
        }, {
          start: moment().add(3, 'day'),
          title: 'Whisper',
          risk: 'whisper'
        }]
      });

      /* When a checkbox changes, re-render events */
      $('input:checkbox.calFilter').on('change', function() {
        $('#calendar').fullCalendar('rerenderEvents');
      });
    });

    function filter(calEvent) {
      var vals = [];
      $('input:checkbox.calFilter:checked').each(function() {
        vals.push($(this).val());
      });
      return vals.indexOf(calEvent.risk) !== -1;
    }
