你好 Stackoverflow，
我在 FullCalendar 中使用了外部拖放功能。我有一种情况，我有两种不同类型的事件，我希望计算如果用户将事件从一个重新调整到从使用拖放放置的那天开始的任何内容，如何计算它调整大小的天数。
这是我的js代码
$(document).ready(function() {
/* initialize the external events
-----------------------------------------------------------------*/
$('#external-events div.external-event').each(function() {
//Do a check to see which class was select and assign bg color with the color of that resource
if($(this).text() == "Birthday"){
bgColor = '#3A87AD'
}
else if($(this).text() == "Holiday"){
bgColor = '#A53333'
}
// create an Event Object (http://arshaw.com/fullcalendar/docs/event_data/Event_Object/)
// it doesn't need to have a start or end
var eventObject = {
title: $.trim($(this).text()), // use the element's text as the event title
backgroundColor: bgColor
};
// store the Event Object in the DOM element so we can get to it later
$(this).data('eventObject', eventObject);
// make the event draggable using jQuery UI
$(this).draggable({
zIndex: 999,
revert: true, // will cause the event to go back to its
revertDuration: 0 // original position after the drag
});
});
/* initialize the calendar
-----------------------------------------------------------------*/
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
right: 'title'
},
editable: true,
droppable: true, // this allows things to be dropped onto the calendar !!!
drop: function(date, allDay) { // this function is called when something is dropped
//Minus vacation days
$('#vacation_days').text($('#vacation_days').text() - 1);
// retrieve the dropped element's stored Event Object
var originalEventObject = $(this).data('eventObject');
// we need to copy it, so that multiple events don't have a reference to the same object
var copiedEventObject = $.extend({}, originalEventObject);
// assign it the date that was reported
copiedEventObject.start = date;
copiedEventObject.allDay = allDay;
// render the event on the calendar
// the last `true` argument determines if the event "sticks" (http://arshaw.com/fullcalendar/docs/event_rendering/renderEvent/)
$('#calendar').fullCalendar('renderEvent', copiedEventObject, true);
// is the "remove after drop" checkbox checked?
if ($('#drop-remove').is(':checked')) {
// if so, remove the element from the "Draggable Events" list
$(this).remove();
}
}
});
});
