首先吐槽这个Fullcalendar这个插件的沙雕文档,都是英文,谷歌翻译又翻译得很笨,查看了很多文档和博客,很都是复制粘贴党.浪费大家时间.

/***/在项目中需要加一个预约功能,后端传给我一个类似下图这样的数据结构,这个就是限制预约时间段,比如data数组中第一项data[0] = [15] 意思是周日 只有15点到16点可以预约.data[1]=[6,“8,12”] 就是周一的6点到7点,8点到下午三点可以预约,如图

1.首先需要下载Fullcalendar以及相关配置

npm install @fullcalendar/core @fullcalendar/daygrid @fullcalendar/timegrid @fullcalendar/moment @fullcalendar/interaction
这个是相关配置代码,其中比较关键的是有个点击事件和select事件重复,最后我选择了select事件,因为这个事件可以被限制范围,

下面列一些花很大精力查到的,用处很大的属性
columnHeaderFormat="ddd"  // 格式化表头,成周一周二...默认为11/19周二,11/20周三...
:first-day="nowDay"  //此处创建一个nowDay方法使当前日期始终在第一列,后面则为当前时期后六天
:business-hours="businessHours" //此处创建一个businessHours数组数据结构类似于[{startTime:"6:00",endTime:"8:00",daysOfWeek:[0]}]  ,daysOfWeek:[0]表示周日,daysOfWeek:[1]表示周一以此类推
:select-allow="handlerAllow"  //此处设置一个handlerAllow方法限制select拉取的范围
min-time="00:00:00" max-time="24:00:00" slot-duration="01:00:00" //此处设置每天时间从什么时候开始结束,以及每段时间的间隔为多少
:eventConstraint="businessHours"   //当事件拖动时,限制拖动到灰色区域
aspectRatio="1.5"   //设置日历的宽高比率 ,发现有超出部分可以适当调整
:editable="true" :eventDurationEditable="false"  //事件可以被拖动,禁止事件下拉(因为项目需要固定只能预约一个小时,下拉会导致时间增加)
:selectConstraint="businessHours"   //这个属性找了两天,贼鸡儿难受,此处限制灰色区域创建预约,就是灰色部分不能被点击,eventConstraint这个只是事件拖动时不会被拖到灰色区域
:event-overlap="false"  //阻止两次预约拖动时重叠

<template>
    <div>
        <div class="calendar">
            <FullCalendar :plugins="calendarPlugins" :all-day-slot="false" :header="{ // 头部样式
                left: 'today',
                right:'next'
            }" :button-text="{ //头部按钮样式
                today: '今天'
            }" :event-overlap="false" :events="event" columnHeaderFormat="ddd" :select-overlap="false"
                :first-day="nowDay" :business-hours="businessHours" :select-allow="handlerAllow" :select-mirror="true"
                selectable="true" min-time="00:00:00" max-time="24:00:00" slot-duration="01:00:00"
                slot-label-format="HH:mm" default-view="timeGridWeek" locale="zh-cn" @eventClick="handleEventClick"
                @eventDrop="handDrop" :eventConstraint="businessHours" @select="handleSelect" aspectRatio="1.5"
                :editable="true" :eventDurationEditable="false" :resourceIds="businessHours"
                :selectConstraint="businessHours" :valid-range="visibleRange" />

其他部分没什么好说的,自己瞅吧,这沙雕插件就是属性难搞,找了好几天.希望大家以后发点干货,别瞎鸡儿转载转载,搜了都是一堆一模一样的东西
