问题描述
我正在使用FullCalendar 3.1.0插件来显示事件。我能够通过一个下拉列表来实现多个事件。但用户只能从单个下拉式筛选器中选择1个选项。我的目标是让机会在每个下拉式筛选器中选择多个选项。我正在使用下拉菜单。但是当我按住CTR并点击选项时，它只显示列表中第一个选项的事件。任何帮助将不胜感激。
I am using FullCalendar 3.1.0 plugin to show events. I was able to implement multiple events with a dropdown. But user is only able to select 1 option from a single dropdown filter. My goal is to give the opportunity to select multiple options in a each dropdown filter. I am using dropdown. But when I hold down CTR and click on options, it only shows events for the first option in the list. Any help would be greatly appreciated.
这是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.

这是我的Javascript：
Here is my Javascript:
$(document).ready(function() {
/* Find all the distinct STATUS_EN and place them into a dropdown list */
// This creates first 2 dropdown dynamically
$.getJSON('json/events.json',function(json){
var usedStatus = []; // Array to keep track of all STATUS_EN that have been seen
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
}
});
});
/* If end_date is null, return start_date */
function isNull(end_date,start_date){
if(end_date !== null){
return end_date;
} else {
return start_date;
}
}

$("body").append(tooltip);

});*/
/**/

});
我的.json文件的样子如下：
Sample of how my .json file looks like:

推荐答案
在一组选定元素上执行.val（）您的 $（'＃status_selector选项：selected'）。val（））将只返回第一个匹配元素的值 - 根据文档的第一行：
Doing .val() on a group of selected elements (e.g. your $('#status_selector option:selected').val()) will only return the value from the first matched element - as per the very first line of the docs: http://api.jquery.com/val/
所以你需要循环并检查所有选择的选项的值，并单独测试它们。这样的事情（未经测试）：
So you need to loop through and check the values of all the selected options, and test for them individually. Something like this (untested):
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);
}
