我有一个日历，我还允许用户删除事件。但是，当按下删除按钮时，它会提示用户删除事件 - 他们说是。但该事件保留在日历上(未删除)，但当我刷新页面时，该事件消失了。任何人都可以看到我的 javascript 我做错了什么吗？谢谢您的帮助。
这是我的代码:
var PUBLIC_KEY = "PUBLIC_KEY",
CALENDAR_ID = "CALENDAR_ID";
var events = []
events = parselocalstorage('events')
var renderPopup = function (jsEvent, start, end, calEvent) {
var $popup = $('#calendar-popup');
var $eventForm = $('#event-form');
$event = $('#event');
var $selectedElmt = $(jsEvent.target);
var relativeStartDay = start.calendar(null, { lastDay: '[yesterday]', sameDay: '[today]' });
var endNextDay = '';
if (relativeStartDay === 'yesterday') {
endNextDay = '[Today at] ';
}
else if (relativeStartDay === 'today') {
endNextDay = '[Tomorrow at] ';
}
else {
endNextDay = 'dddd ';
}
$('.start-time').html(
'<time datetime="' + start.format() + '">'
+ start.calendar(null, {
lastWeek: 'L LT',
nextWeek: 'dddd LT',
sameElse: 'L LT'
})
+ '</time>'
);
if (calEvent) {
$eventForm.hide();
$event.children('header').html(`<i class="fa fa-calendar-o"></i>`);
$event.find('.location').text(calEvent.location ? calEvent.location : '(No location information.)');
$event.find('.details').text(calEvent.details ? calEvent.details : '');
$event.show();
}
else {
$event.hide();
$('#event-start').val(start.format('YYYY-MM-DD[T]HH:mm'));
$eventForm.show();
}
var leftPosition = 0;
var $prong = $('.prong');
var prongPos = 0;
if ($selectedElmt.hasClass('fc-highlight')) {
leftPosition = $selectedElmt.offset().left - $popup.width() + ($selectedElmt.width() / 2);
if (leftPosition <= 0) {
leftPosition = 5;
prongPos = $popup.width() - $selectedElmt.offset().left - 30
}
else {
prongPos = 15;
}
$popup.css('left', leftPosition);
$prong.css({
'left': '',
'right': prongPos,
'float': 'right'
});
}
else {
leftPosition = jsEvent.originalEvent.pageX - $popup.width() / 2;
if (leftPosition <= 0) {
leftPosition = 5;
}
prongPos = jsEvent.originalEvent.pageX - leftPosition - ($prong.width() * 1.7);
$popup.css('left', leftPosition);
$prong.css({
'left': prongPos,
'float': 'none',
'right': ''
});
}
var topPosition = (calEvent ? jsEvent.originalEvent.pageY : $selectedElmt.offset().top) - $popup.height() - 15;
if ((topPosition <= window.pageYOffset)
&& !((topPosition + $popup.height()) > window.innerHeight)) {
$popup.css('top', jsEvent.originalEvent.pageY + 15);
$prong.css('top', -($popup.height() + 12))
.children('div:first-child').removeClass('bottom-prong-dk').addClass('top-prong-dk')
.next().removeClass('bottom-prong-lt').addClass('top-prong-lt');
}
else {
$popup.css('top', topPosition);
$prong.css({ 'top': 0, 'bottom': 0 })
.children('div:first-child').removeClass('top-prong-dk').addClass('bottom-prong-dk')
.next().removeClass('top-prong-lt').addClass('bottom-prong-lt');
}

最佳答案
你可以把 $('#calendar').fullCalendar('refetchEvents');像这样的函数末尾。
element.find(".I_delete").click(function () {
$('#calendar-popup').hide();
if (confirm('are you sure want to delete event?')) {
$('#calendar').fullCalendar('removeEvents', event._id);
var index = events.map(function (x) { return x.id; }).indexOf(event.id);
events.splice(index, 1);
localStorage.setItem('events', JSON.stringify(events));
events = parselocalstorage('events')
$('#calendar').fullCalendar('refetchEvents');
}
});
我希望这能解决您的问题:)。
关于javascript - 删除按钮不会立即在 JavaScript 中从 View 中删除？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61400160/
