有做浏览单的网站如何seo推广

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）： 

::v-deep .kalendar {&-header {text-align: center;margin: 10px 16px 0 16px;.current-monuth {font-size: 16px;letter-spacing: 0;font-weight: 500;margin-left: 15%;color: #262626;font-family: PingFangSC-Medium;i {cursor: pointer;}}.el-radio-group {float: right;}.el-radio-button__orig-radio:checked + .el-radio-button__inner {background: #ffffff;box-shadow: -1px 0 0 0 transparent;border: 1px solid rgba(199, 0, 11, 1);font-family: PingFangSC-Medium;font-size: 12px;color: #c7000b;letter-spacing: -0.04px;font-weight: 500;}.el-radio-button__inner:hover {color: #c7000b;}}.calender-dot-box {width: 100%;bottom: -8px;position: absolute;span {width: 6px;height: 6px;margin-right: 3px;border-radius: 50%;display: inline-block;&:last-of-type {margin-right: 0;}}.endPlan {background-color: #d61212;}.applyEndPlan {background-color: #ffd100;}}.el-calendar {&__body {padding: 10px 16px;}.is-today {.el-calendar-day {.calender-date {width: 34px;height: 34px;margin: 0 auto;color: #ff534f;border-radius: 10px;background: #fff;box-shadow: none;}}}&__header {display: none;}.current {.el-calendar-day {color: #262626;}}.prev,.next {color: #bfbfbf;}&-day {padding: 0;font-weight: 700;font-size: 16px;letter-spacing: 0;text-align: center;position: relative;transition: color 0.3s;font-family: DINAlternate-Bold;}&-table {th {font-family: PingFangSC-Regular;font-size: 16px;color: #262626;letter-spacing: 0;text-align: center;line-height: 34px;font-weight: 400;padding: 0;&:last-of-type,&:first-of-type {color: #ff564e;}}td {border: none;&.is-selected {background-color: transparent;}}.el-calendar-day {height: 34px;line-height: 34px;&:hover {background-color: transparent;}.calendar-isSelected {width: 34px;height: 34px;margin: 0 auto;color: #fff;border-radius: 10px;background: #ff534f;box-shadow: 0px 0px 2px 0px rgba(238, 88, 64, 1);}}}}

再看看子组件里面，先看月的：

<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：

<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：

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。

周视图效果图：
