如何删除完整日历中最后选定的事件?



如果我点击日历中的特定日期进行预约,则会出现一个模式,选择用户,服务,日期和时间并留下评论,模态有两个按钮,第一个用于预约,第二个用于取消约会问题是如果我想选择另一个日期,我看到两个事件, 我之前单击的一个和当前单击的,如果单击">约会"按钮,将创建两个约会,我不会发生这种情况.

请,当我单击">取消"按钮时如何删除上次单击的事件。

日历块

<div class="row">

eventClick: function(calEvent, jsEvent, view) {

// delete event in backend
jQuery.post(

viewRender: function (view,element) {

在我的 eventData 中,我添加了一个随机 ID,只是为了查看我是否单击了取消按钮,所有单击的事件都会被删除,它们会从日历中完全删除,但它们仍然存在,如果我确认约会,我可以看到它们,我在仪表板内收到 4 或 5 条通知。

eventClick中,如果我直接单击事件,它会询问我是否要删除它,实际上,当我单击取消按钮而不是之后时,删除过程应该发生。

如上所述,解决了@ADyson的问题,我需要在.on()旁边使用.off()来防止向同一元素添加更多事件处理程序,您只需键入:

$(selector).off("change");

$(selector).off("click");

这取决于您的代码。

另一件事要提一下,我创建了一个 if 语句,如果日期有效,则只从日历中选择选择日期,如果日期无效,则不会选择它,这是更新的select:事件:

select: function(start, end, jsEvent, allDay, view) {
if (start.weekday()!=0 && start.weekday()!=6) {
$('#calendar').fullCalendar('select',start);
}
events: [
],
}

另外不要忘记添加unselectAuto并将其切换到配置中的false,以避免在取消事件时自动取消选择,在我们的情况下,正如我上面提到的,我们需要选择和取消选择仅单击的元素。

我意识到为什么每次单击都会添加越来越多的事件的另一件事是,因为我必须在$("#serviceSet").val($(this).find("option:selected").attr("value"));之后删除了额外的eventData,这也导致了问题。

我稍后会做更多的工作,但告诉知道问题得到解决.

最终,我真的要再次感谢@ADyson的兴趣:)
