功能:
1.日历可以周视图、月视图切换;
2.点击月视图中日期可以切换到对应周视图;
3.点击周视图查看当日对应数据;
4.周、月视图状态下,点击前后按钮,分别切换对应上下的周、月;
5.点击回到今天,立即切回到周、月视图下对应的当日;
引用dayjs处理日期,结合el-calendar完美实现。
要注意的是,日历显示周的话,传的日期范围要按照计算所在星期,比如我们的需求是周日为每周起始日,那么就要给周日的日期和周六日期为起始日,月视图我不想再去计算日期范围了,就直接用了:value,注意用的不是v-model而是value,因为value是单向的,v-model是双向数据绑定了。

自定义日历样式(没有用日历原先的头,全部自己重写的,还不错):

再看看子组件里面,先看月的:
javascript
<template>
<!-- 月日历 -->
<el-calendar :value="calendarValue" :first-day-of-week="7" value-format="YYY-MM">
<template slot="dateCell" slot-scope="{ date, data }">
<div v-if="selectedDay === data.day" class="calendar-isSelected" @click="handleDate($event, date, data)">
{{ date.getDate() }}
</div>
<div v-else class="calender-date" @click="handleDate($event, date, data)">
{{ date.getDate() }}
</div>
<div class="calender-dot-box" @click="handleDate($event, date, data, 'dot')">
<template v-for="(item) in dateLists">
<span class="applyEndPlan" v-if="item.date === data.day && item.applyEndPlanNum > 0"></span>
<span class="endPlan" v-if="item.date === data.day && item.endPlanNum > 0"></span>
</template>
</div>
</template>
</el-calendar>
</template>
<script>
export default {
components: {},
name: "CalendarMonth",
props: {
selectedDay: {
type: String,
default: "",
},
calendarValue: {
type: String,
default: new Date(),
},
dateList: {
type: Array,
default: () => {
return [];
},
},
},
watch: {
dateList: {
handler(list) {
this.dateLists = list;
},
immediate: true,
},
},
data() {
return { monthDate: this.calendarValue, dateLists: [] };
},
created() { },
methods: {
handleDate(e, date, data) {
this.$emit("getPlanList", data);
},
},
};
</script>
<style lang="scss" scoped></style>
周日历组件:
javascript
<template>
<!-- 周日历 -->
<el-calendar :range="rangeArr" :first-day-of-week="7" value-format="YYY-MM">
<template slot="dateCell" slot-scope="{date,data}">
<div v-if="selectedDay === data.day" class="calendar-isSelected" @click="handleDate($event, date, data)">
{{ date.getDate() }}</div>
<div v-else class="calender-date" @click="handleDate($event, date, data)">{{ date.getDate() }}</div>
<div class="calender-dot-box" @click="handleDate($event, date, data)">
<template v-for="(item) in dateList">
<span class="applyEndPlan" v-if="item.date === data.day && item.applyEndPlanNum > 0"></span>
<span class="endPlan" v-if="item.date === data.day && item.endPlanNum > 0"></span>
</template>
</div>
</template>
</el-calendar>
</template>
<script>
export default {
components: {}, name: 'CalendarWeek', props: {
selectedDay: {
type: String, default: '',
}, rangeArr: {
type: Array,
default: () => {
return [];
}
}, dateList: {
type: Array, default: () => {
return [];
}
}
}, data() {
return {
}
}, created() {
}, methods: {
handleDate(e, date, data) {
// console.log(e,date,data)
this.$emit('getPlanList', data)
},
}
}</script>
<style lang="scss" scoped></style>
其实应该把日历组件二次封装一下,就不用单独再去写周、月日历子组件了,有空了可以试试。
不过不得不再吐槽一句,elementui的日历组件,给提供的API真心的少,功能很简单。。。
最终效果图:
月视图效果图:
![](https://i-blog.csdnimg.cn/direct/fcbae093048d44f59dad8fc045de9c8e.png)
月视图下,有时候会出现整整一行的灰色日期,看起来不是很美观,那么就需要操作dom,通过js判断,操作dom来处理。大概思路就是,先通过 document.querySelectorAll('.el-calendar-table__row') 获取到所有.el-calendar-table__row的元素节点lists,然后循环遍历这些节点,若其子元素class中含有.current,那么就说明是带有当月的日期,则不改变样式,若不含,则说明这整行都是前\后月的日期,那么就可以把该.el-calendar-table__row的css里面加上属性display:none。
