我试图创建某种日历应用程序
当您单击一个空白框时,它会显示一个表单来创建一个事件。
你使用" ANTERIOR"或" SIGUIENTE"导航日历。
当您单击一个框直到您单击" ANTERIOR"或" SIGUIENTE"然后停止工作。
这是完整的代码:

答案 0 :(得分:1)
问题是,当您点击#prev-week
或#next-week
时,您实际上会调用删除部分现有HTML的函数#calender-wrapper
然后创建一个新的日历包装器,其中包含.availabe
个类的元素。
jQuery .click
事件绑定方法,称为直接绑定方法,只有在您删除#calender-wrapper
jQuery认为.availabe
元素时,才能与文档中的exesting元素一起使用作为新对象,即使它们具有相同名称的同一类。
或者,使用委派事件来附加事件处理程序。像...
$( document ).on( "event-name", ".dynamic-element-selector", function() {
##code;
});
看,我完全不了解事情,为什么会发生这种情况,但这是真的。
事件处理程序仅绑定到当前选定的元素;它们必须在您的代码调用.on()时存在。要确保元素存在且可以选择,请将脚本放在HTML标记中的元素之后,或者在文档就绪处理程序中执行事件绑定。或者,使用委派事件来附加事件处理程序。

请将以下部分的脚本替换为:
$(document).ready(function() {
$("#calendar").append(nav);
// initiate the calendar
showCalendar(weekStart);
// previous week button handler
$("#prev-week").click(function() {
prevWeek();
});
// Next week button handler
$("#next-week").click(function() {
nextWeek();
});
$('.available').click(function() {
var data = $(event.target).data();
showAddEvent(data);
});
});
致:
$(document).ready(function() {
$("#calendar").append(nav);
// initiate the calendar
showCalendar(weekStart);
// previous week button handler
$("#prev-week").click(function() {
prevWeek();
});
// Next week button handler
$("#next-week").click(function() {
nextWeek();
});
$(document).on('click', '.available', function() {
var data = $(this).data();
showAddEvent(data);
});
});
