jquery fullcalendar event filtering

Question

Is there any method to dynamic filter events on client side in fullcalendar? When I get events from server (json_encoded) I assign my own parameter "school_id" to every event. After fullcalendar is ready, I want to dynamic filter events with "select".

I add "select" element on page like this:

<select id='school_selector'>
      <option value='all'>All schools</option>
      <option value='1'>school 1</option>
      <option value='2'>school 2</option>
</select>

And in javascript code I add:

jQuery("#school_selector").change(function(){
    filter_id = $(this).val();
    if (filter_id != 'all') {
        var events = $('#mycalendar').fullCalendar( 'clientEvents', function(event) {
        if((filter_id == 'all') ) {
            return true;
        }else{
                //what I need to write here to dynamic filter events on calendar?
        });
    }
 });

But it's does not work. Any help will be great.thanks.

Since version 2 of fullCalendar you can use the eventRender callback to selectively render an event. Combine this with a call to the rerenderEvents method in your onChange handler, and your events should automatically update based on the selected option.

$('#mycalendar').fullCalendar({
    events: [
        {
            title: 'Event 1',
            start: '2015-05-01',
            school: '1'
        },
        {
            title: 'Event 2',
            start: '2015-05-02',
            school: '2'
        },
        {
            title: 'Event 3',
            start: '2015-05-03',
            school: '1'
        },
        {
            title: 'Event 4',
            start: '2015-05-04',
            school: '2'
        }
    ],
    eventRender: function eventRender( event, element, view ) {
        return ['all', event.school].indexOf($('#school_selector').val()) >= 0
    }
});

$('#school_selector').on('change',function(){
    $('#mycalendar').fullCalendar('rerenderEvents');
})
