uniapp 日历
先看效果图！！！
上代码：
<view class="content">
<ren-calendar ref='ren' :markDays='markDays' :headerBar='false' @onDayClick='onDayClick'></ren-calendar>
<view class="change">选中日期：{{curDate}}</view>
</view>
import RenCalendar from '@/components/ren-calendar/ren-calendar.vue'
export default {
components:{
RenCalendar
},
data() {
return {
curDate:'',
markDays:[]
};
},
onLoad() {
},
onReady() {
let today = this.$refs.ren.getToday().date;
this.curDate = today;
this.markDays.push(today);
},
methods: {
// 展开日历
onDayClick(data){
this.curDate = data.date;
}
}
};
ren-calendar.vue组件代码：
