vue+elementUI簡單的實現日歷功能，供大家參考，具體內容如下

<div class='calender2'> <div class='date-headers'> <div class='date-header'> <div><el-button type='primary' @click='handlePrev'><i class='el-icon-arrow-left'></i>上一月</el-button></div> <div>{{ year }}年{{ month }}月{{ day }}日</div> <div><el-button type='primary' @click='handleNext'>下一月<i class='el-icon-arrow-right'></i></el-button></div> <div><el-button type='primary' icon='el-icon-refresh-left' @click='refresh'></el-button></div> </div> </div> <div class='date-content'> <div class='week-header'> <div v-for='item in [’日’,’一’,’二’,’三’,’四’,’五’,’六’]' :key=item >{{ item }} </div> </div> <div class='week-day'> <div v-for='item in 42' :key='item' @click='handleClickDay(item - beginDay)' ><div v-if='item - beginDay > 0 && item - beginDay <= curDays' : >{{ item - beginDay }}</div><div v-else-if='item - beginDay <= 0'>{{ item - beginDay + prevDays }}</div><div v-else>{{ item - beginDay -curDays }}</div> </div> </div> </div></div>

## javascript
