根据输入中的值重新获取完整日历事件



我有一个日历,可以从MySQL数据库获取现场工作许可证的事件。当页面打开时,将从数据库中获取事件并将其添加到日历中。

我想在日历中添加一个搜索工具,用户在其中将文本输入到 5 个输入中的任何一个,单击应用,日历就会根据输入的条件获取事件。

页面打开时第一次获取事件时使用通配符通过 ajax 查询数据库,这没有问题。然后,我调用 FullCalendar removeEvents 和 refetchEvents 方法来使用新值运行 ajax,但不包括任何输入的文本,仅使用原始值。

我的Javascript在下面

$(document).ready(function(){
document.getElementById('left_nav').innerHTML = sessionStorage.getItem('left_nav');
document.getElementById('company').innerHTML = " " + sessionStorage.getItem('company');
document.getElementById('profile_image').innerHTML = sessionStorage.getItem('profile_image');
//Add value of inputs to variables
var select_project = $('#select_project').val();
var select_site = $('#select_site').val();
var select_area = $('#select_area').val();
var select_requester = $('#select_requester').val();
var select_line_manager = $('#select_line_manager').val();
var today = new Date();
var dd = today.getDate();
var m = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
today = yyyy+'/'+m+'/'+dd;
var popup_button;
$('#clear').click(function(e) {

})
$('#apply').click(function(e) {
//Clear all events and refetch
$('.fullcalendar-event').fullCalendar('removeEvents');
$('.fullcalendar-event').fullCalendar('refetchEvents');
})
// Event colors
$('.fullcalendar-event').fullCalendar({

您遇到的问题是,作为事件的一部分传递到 fullCalendar 中的data对象是静态的。创建日历时,您将为 fullCalendar 提供处于该对象当时的状态。fullCalendar会复制它,并在获取事件时使用它。它无法读取您对该对象或其中的变量所做的任何更改。

解决方案是将data定义为回调函数,每当需要刷新事件时,fullCalendar 都可以重新运行该函数。这样,它就有一些代码可以实际执行,以便读取变量的最新值,而不仅仅是静态对象。

你这样写:

events: {
//Get events based on criteria with wildcards
type: "POST",
url: 'php_files/calender_php_files/populate_calender.php',
data: function() {
return {
client_id: sessionStorage.getItem('client_id'),
access_id: sessionStorage.getItem('access_id'),
select_project: '%' + select_project + '%',
select_site: '%' + select_site + '%',
select_area: '%' + select_area + '%',
select_requester: '%' + select_requester + '%',
select_line_manager: '%' + select_line_manager + '%'
};
}
},

此处记录了这一点:https://fullcalendar.io/docs/event_data/events_json_feed/在标题为"动态数据参数"的最后一节中。

附言在调用refetchEvents之前应该不需要使用removeEvents- 重新获取操作已经自动清除日历并将其替换为最新数据。
