责编:menVScode 2020-10-12 15:59 阅读(57)

日历功能:

1. 默认选择今天的日期时间段

(1) 默认状态(默认选择当前日期的时间段(蓝底背景色代表选中时间段);

(2) 当前日期之前的时间不可以选择(禁用了点击事件);

(3) 当日历上的操作的年份月份小于当前时间的年份月份时禁止点击上一月的按钮;

效果图:


2. 选中状态

(1) 可以跨年分跨月份选择;

(2) 点击取消按钮时回复到默认的选择时间;

效果图:


代码如下:

   <!-- <div>时间段:{{starttime}}至{{endtime}}</div> -->
 
    <div class="mobile-top">

        <p class="start-date">{{starttime}}</p>
      </div>
      <div class="unsel-time">
        <p>结束时间</p>
        <p class="end-date">{{endtime==''?'请选择结束日期':endtime}}</p>
      </div>
    </div>
 
    <div class="title">
      <div class="btn" @click="last()" 
       :class="(month<=nowmonth)&&(Year<=nowYear)?'noclick':'' ">上一月</div>
      <div class="text">{{Year}}年{{month}}月</div>
      <div class="btn" @click="next()">下一月</div>
    </div>
