Fullcalendar这个插件挺好，就是很多方法感觉官方文档也没怎么说，导致上手难度大，而且有些默认事件真的不太友好...废话不多说，先上效果图！

1、效果GIF 

1.1 基本按钮功能

1.2  事件hover显示

 

1.3 事件添加、编辑、状态修改 

 

1.4 日历事件搜索 

 

2、 代码实现

 2.1 Fullcalendar日历、el-popover弹窗

        Fullcalendar@5.11.3引入后，要设置一大堆参数calendarOptions，包括显示时间区域、默认视图、是否显示全天类型、中文界面、事件的操作函数等，具体的一些设置内容，见下面代码的注释。

<template>         
 <FullCalendar
            class="calendar"
            ref="fullCalendar"
            :options="calendarOptions"
            ><template v-slot:eventContent="arg">
              <el-popover
                :append-to-body="true"

        //     return false;
        //   }
        //   return true;
        // },
        weekends: true, //是否显示周末，设为false则不显示周六和周日
        selectable: true, //是否可以选中日历格
        editable: false, //是否可以进行（拖动、缩放）修改
        navLinks: true, //天链接
        select: this.selectDate, //选中日历格事件
        eventClick: this.handleEventClick, //选中备忘录事件
        eventsSet: this.handleEvents,
        events: this.getCalendarList, //获取数据源
        eventMouseEnter: this.eventMouseEnter, //鼠标悬浮事件
        slotEventOverlap: true, //相同时间段的多个日程视觉上是否允许重叠，默认true允许
        eventResize: this.onEventResize, // 事件时间区间调整
        eventDrop: this.onEventResize, // 事件Drag-Drop事件
        eventMouseLeave: this.eventMouseLeave, // 鼠标移出事件发生的事件
      },
    };
  },
}
  </script>

         在这里，鼠标在事件上面经过时，会显示一个弹出窗，如下图。可见，弹出框有：是否已完成，开始时间，图列说明（可以是图片、GIF等），文字说明、链接或是附件。以上的这些都是用el-popover实现，用了v-slot:eventContent="arg"，将日历的数据进行处理。图片的显示需要修改源码才能显示，不然有bug显示不出来，修改的源码见此文章第3节内容。

 2.2 Fullcalendar日历自定义头部

        在calendarOptions设置里，修改headerToolbar，设置为false。

         然后写好自己的html代码，并调整好css样式。

         绑定自定义按钮的函数功能，主要是利用了calendarApi自带的函数功能，包括视图切换、月日视图切换、往前和往后功能等，当然搜索功能是自己定义的。

  2.3 搜索功能

        这里是onSearch函数功能，主要是在前端对events的过滤，然后再设置视图为list视图，注意这个视图在日历头部的功能区是没有的，但是是Fullcalendar内置的。当搜索框为空或者清空搜索字符后，需要重新请求后端数据。 

3、Fullcalendar源码修改

3.1 修改源码main.js的地址：

 3.2 添加的show_pic函数/方法：

    CalendarApi.prototype.show_pic = function (arg) {
        var state = this.getCurrentData();
        this.unselect();
        // 出现图片的关键
        this.dispatch({
            type: 'CHANGE_DATE',
            dateMarker: state.dateEnv.createMarker(arg.view.currentStart),
        });
    };

4、Vue源码
