选中“Fullcalendar eventRender”的多个复选框

Question

在我的完整日历中，我有几个复选框，我希望它们像过滤器一样反应。简而言之：我想筛选一个、全部、三个、两个（多个）。。。等等。

我走了这么远，我可以选择一个复选框，它会返回正确的事件，但当然，它不适用于两个或更多的复选框。但我不知道，怎么做！我的Javascript技术不是很好。

我使用Json文件获取事件，该文件是我在模型中使用RubyonRails 4创建的。但我不想拆散这个Json。所以我在搜索一个完整的Javascript版本。

我想，代码会更好地显示我的意思。

Html:

<input id="hamburg" class="event_filter_box" name="event_filter_select" type="checkbox" value="Hamburg">Hamburg</input>
<input id="schleswig-holstein" class="event_filter_box" name="event_filter_select" type="checkbox" value="Schleswig-Holstein">Schleswig-Holstein</input>
<input id="party" class="event_filter_box" name="event_filter_select"  type="checkbox" value="Party">Party</input>
<input id="concert" class="event_filter_box" name="event_filter_select" type="checkbox" value="Concert">Concert</input>
<input id="festival" class="event_filter_box" name="event_filter_select" type="checkbox" value="Festival">Festival</input>
<div id="calendar"></div>

Javascript：

$(document).ready(function() {
  $('input[class=event_filter_box]').change(function() {
    $('#calendar').fullCalendar('rerenderEvents');
  });
});

$("#calendar").fullCalendar({
  events: [
    {
      title: 'Party Event in Hamburg',
      start: '2015-11-11',
      address_city: 'Hamburg',
      kind: 'Party',
    }, 
    {
      title: 'Conzert Event in Hamburg',
      start: '2015-11-10',
      address_city: 'Hamburg',
      kind: 'Concert',
    }, 
    {
      title: 'Festival Event in Schleswig-Holstein',
      start: '2015-11-08',
      end: '2015-11-12',
      address_city: 'Schleswig-Holstein',
      kind: 'Festival',
    }, 
  ],
  defaultView: "basicWeek",
  eventRender: function eventRender( event, element, view ) {
    if ($('input[id=hamburg]').is(':checked')) {
      return ['all', event.address_city].indexOf($('#hamburg').val()) >= 0
    } else if ($('input[id=schleswig-holstein]').is(':checked')) {
      return ['all', event.address_city].indexOf($('#schleswig-holstein').val()) >= 0
    } else if ($('input[id=party]').is(':checked')) {
      return ['all', event.kind].indexOf($('#party').val()) >= 0
    } else if ($('input[id=concert]').is(':checked')) {
      return ['all', event.kind].indexOf($('#concert').val()) >= 0
    } else if ($('input[id=festival]').is(':checked')) {
      return ['all', event.kind].indexOf($('#festival').val()) >= 0
    }
  },
});

对于多选，Javascript是如何实现的？感谢之前=）

Fiddle演示：http://jsfiddle.net/gohrbk41/1/

我稍微更改了HTML，为数据类型添加了标签，以区分城市和种类

<!-- I added data-type to the checkboxes -->
<input id="hamburg" class="event_filter_box" name="event_filter_select" type="checkbox" value="Hamburg" data-type="address_city">Hamburg</input>
<input id="schleswig-holstein" class="event_filter_box" name="event_filter_select" type="checkbox" value="Schleswig-Holstein" data-type="address_city">Schleswig-Holstein</input>
<input id="party" class="event_filter_box" name="event_filter_select"  type="checkbox" value="Party" data-type="kind">Party</input>
<input id="concert" class="event_filter_box" name="event_filter_select" type="checkbox" value="Concert" data-type="kind">Concert</input>
<input id="festival" class="event_filter_box" name="event_filter_select" type="checkbox" value="Festival" data-type="kind">Festival</input>
<div id="calendar"></div>

对于javascript

$(document).ready(function() {
  $('input[class=event_filter_box]').change(function() {
    $('#calendar').fullCalendar('rerenderEvents');
  });
});

$("#calendar").fullCalendar({
  events: [
    {
      title: 'Party Event in Hamburg',
      start: '2015-11-11',
      address_city: 'Hamburg',
      kind: 'Party',
    }, 
    {
      title: 'Conzert Event in Hamburg',
      start: '2015-11-10',
      address_city: 'Hamburg',
      kind: 'Concert',
    }, 
    {
      title: 'Festival Event in Schleswig-Holstein',
      start: '2015-11-08',
      end: '2015-11-12',
      address_city: 'Schleswig-Holstein',
      kind: 'Festival',
    }, 
  ],
  defaultView: "basicWeek",
  eventRender: function eventRender( event, element, view ) {
      var display = true;
      var addresses = [];
      var kinds = [];
      // Find all checkbox that are event filters that are enabled
      // and save the values.
      $("input[name='event_filter_select']:checked").each(function () {
          // I specified data-type attribute in above HTML to differentiate
          // between locations and kinds of events.
          // Saving each type separately
          if ($(this).data('type') == 'address_city') {
              addresses.push($(this).val());
          }
          else if ($(this).data('type') == 'kind') {
              kinds.push($(this).val());
          }
      });
      // If there are locations to check
      if (addresses.length) {
          display = display && addresses.indexOf(event.address_city) >= 0;
      }
      // If there are specific types of events
      if (kinds.length) {
          display = display && kinds.indexOf(event.kind) >= 0;
      }
      return display;
  },
});
