Question

我通过fullcalendar建立日历。

我做了一个ajax按钮，只是从另一个php页面获取事件。

ajax按钮工作正常，我能够通过事件获得json，并且我得到一个漂亮的月历显示（在我的第一个cj上的ajax按钮）。

我唯一的问题是：当我点击ajax按钮上的seconed时间时，日历不会重新加载/重新发布/渲染..并且我坚持使用第一个日历（这对我来说是无关紧要的）。

任何人都知道问题是什么，为了在每次点击ajax按钮时重新发布新日历，我该怎么办？

这是代码：

<form id="my-form-id" method="post" action="Calendar_form3.php"> Year:
    <INPUT NAME="gregorian_year" SIZE=4 MAXLENGTH=4 value="2016">(1-6000) Latitude:
    <INPUT NAME="latitude" value="40.7127"> Longitude:
    <INPUT NAME="longitude" value="-74.0059"> <button id="ajax-button" type="button">Ajax button</button> </form>
<script>
    function displayCalendar() {
        var target = document.getElementById("main");
        var formData = new FormData(document.getElementById("my-form-id"));
        console.log(formData);
        var xhr = new XMLHttpRequest();
        xhr.open('post', 'JewishCalendar_form3.php', true);
        xhr.onreadystatechange = function() {
            console.log('readyState: ' + xhr.readyState);
            if (xhr.readyState == 2) {
                target.innerHTML = 'Loading...';
            }
            if (xhr.readyState == 4 && xhr.status == 200) {
                var Month_details_for_display = JSON.parse(xhr.responseText);
                //var Month_details_for_display= JSON.parse(Month_details_for_display2);
                target.innerHTML = "funciton will start working...";
                displayCalendar222(Month_details_for_display);
            }
        }
        xhr.send(formData);
    }

    function displayCalendar222(Month_details_for_display) {
        alert("Hello! I am an alert box!!");
        var Events_In_Json = Month_details_for_display['EventsInSameStractureForAll'];
        var json_backgrundColor = Month_details_for_display['Big_Calendar_cell_background_color'];
        var json_iconstring = Month_details_for_display['iconString'];
        var DefaulteDateForFullCalendarISO8601 = Month_details_for_display['fullMonthDetails']['DefaulteDateForFullCalendarISO8601'];
        $('#calendar').fullCalendar({
            header: {
                left: 'prev',
                center: 'title',
                right: 'next'
            },
            events: Events_In_Json,
            fixedWeekCount: false,
            defaultDate: DefaulteDateForFullCalendarISO8601,
            dayRender: function(date, cell) {
                var cellDate = date.format('D');
                if (!cell.hasClass('fc-other-month')) {
                    //if this if is true that means that the day belongs to the current relevent month (and not the prev \ next month)
                    cell.css('background-color', json_backgrundColor[cellDate]);
                    //from here: cheking which icons to show

<div id='main'> result here </div>
<div id='calendar'></div>

第二次点击按钮时，您应该拨打以下内容：

$('#calendar').fullCalendar('render');

或者在再次渲染之前完全破坏日历，例如：

$('#calendar').fullCalendar('destroy')
              .empty()
              .fullCalendar({
                 //...
              });
