FullCalendar在單個篩選器中選擇多個事件

Question

我正在使用FullCalendar 3.1.0插件來顯示事件。我能夠通過下拉菜單實現多個事件。但用戶只能從單個下拉式過濾器中選擇1個選項。我的目標是提供在每個下拉篩選器中選擇多個選項的機會。我正在使用下拉菜單。但是，當我按住CTR並點擊選項時，它僅顯示列表中第一個選項的事件。任何幫助將不勝感激。

下面是HTML：

<!-- Main view: Title and calendar --> 
<div class="container"> 
    <div class="row"> 
     <div class="col-xs-12"> 
      <h1 id="cal_title">Change Calendar</h1> 
      <div class="search_bar"> 
       <ul id="menu"> 
        Search By: 
        <li> 
         <select id="status_selector" multiple> 
          <option value="all" selected="selected">Status Types - All</option> 
         </select> 
        </li> 
        <li> 
         <select id="group_selector" multiple> 
          <option value="all" selected="selected">Group - All</option> 
         </select> 
        </li> 
        <li> 
         <select id="changeType_selector" multiple> 
          <option value="all" selected="selected">Type of Change - All</option> 
          <option value="6250">Emergency Change</option> 
          <option value="6882">Expedited Change</option> 
          <option value="6249">Normal Change</option> 
          <option value="9999">Standard Change</option> 
         </select> 
        </li> 
        <li> 
         <select id="downtime_selector" multiple> 
          <option value="all" selected="selected">Downtime - All</option> 
          <option value="Yes">Yes</option> 
          <option value="No">No</option> 
         </select> 
        </li> 
       </ul> 
      </div> 
      <div id="calendar"></div> 
      <div id="footer">To ensure optimal performance, only changes created in the past 90 days are shown.

這裏是我的javascript：

      var usedGroup = []; // Array to keep track of all group_selector that have been seen 

      // For each object, store the status/group in predefined variables 
      $.each(json, function(i,v){ 
       // If STATUS_EN has not been seen 
       if (usedStatus.indexOf(v.STATUS_EN) == -1){ 
        usedStatus.push(v.STATUS_EN); // Add STATUS_EN to usedStatus 
       } 
       // If responsible_group has not been seen 
       if (usedGroup.indexOf(v.responsible_group) == -1){ 
        usedGroup.push(v.responsible_group); // Add responsible_group to usedStatus 
       } 
      }); 

      // Sort both array variables in alphabetical order. 
      usedStatus.sort(); 
      usedGroup.sort(); 

      // Create the dropdown 
      usedStatus.forEach(function(value){ 
       if (value != undefined){ // If STATUS_EN is not undefined 
        $("#status_selector").append('<option value="'+value+'">'+value+'</option>'); // Create an option for the dropdown list 
       } 
      }); 
      usedGroup.forEach(function(value){ 
       if (value != undefined){ // If responsible_group is not undefined 
        $("#group_selector").append('<option value="'+value+'">'+value+'</option>'); // Create an option for the dropdown list

     });

樣的我以.json文件看起來像：

[ 
{ 
    "start": "2016-12-2T17:0:00", 
    "end": "2016-12-2T17:0:00", 
    "title": "12/2/2016 5:00 PM - group1", 
    "url": "https://sample.com", 
    "text": "some needed text", 
    "description": "description of event", 
    "REQUEST_ID": 462820, 
    "STATUS_EN": "Open", 
    "downtime": "No", 
    "change_type": "9999", 
    "responsible_group": "group1", 
    "RFC_NUMBER": "C201612_09454" 
},

    "start": "2017-2-1T21:0:00",

}

Answer 1

做.VAL（）對一組選定的元素（例如您的$('#status_selector option:selected').val()）只會返回來自第一個匹配元素的值 - 如pe r文檔的第一行：http://api.jquery.com/val/

因此，您需要遍歷並檢查所有選定選項的值，然後單獨測試它們。像這樣（未經測試）：

  eventRender: function eventRender(event, element, view){ 
      var statusMatch = false; 
      var statusArr = ['all',event.STATUS_EN]; 

      $('#status_selector option:selected').each(function(index, el) 
      { 
       if (statusArr.indexOf($(this).val()) > = 0) statusMatch = true; 
      }); 

      var groupMatch = false; 
      var groupArr = ['all',event.responsible_group]; 

      $('#group_selector option:selected').each(function(index, el) 
      { 
       if (groupArr.indexOf($(this).val()) > = 0) groupMatch = true; 
      }); 

      var changeMatch = false; 
      var changeArr = ['all',event.change_type]; 

      $('#changeType_selector option:selected').each(function(index, el) 
      { 
       if (changeArr.indexOf($(this).val()) > = 0) changeMatch = true; 
      }); 

      var downtimeMatch = false; 
      var downtimeArr = ['all',event.downtime]; 

      $('#downtime_selector option:selected').each(function(index, el) 
      { 
       if (downtimeArr.indexOf($(this).val()) > = 0) downtimeMatch = true; 
      }); 

      return (statusMatch && groupMatch && changeMatch && downtimeMatch); 
     }
