用vue写一个日历

之前在上家公司做过一个公司人员考勤的东西，里面需要用到日历，当时自己用vue随便写了一个，比较简单，删掉了其他功能的代码，只留下日历，直接看代码

<template> <div class='lookForMonth_wrapper'> <div class='lookForMonth_top'> <div class='selectDate'> <div>{{year}} 年 {{month}} 月</div> <div class='upDownSelect'> <div @click='dateUp'></div> <div @click='dateDown'></div> </div> </div> </div> <div :style='calendarStyle'> <div v-for='(item,index) in calendarData' :key=’index’ :class='{ash:item.color===’ash’,date:index>6&&item.color!==’ash’}'> <p class='dateEdit'>{{item.label}}<i v-if='item.color!==’ash’&&index>=7'></i></p> <p v-if=’index>6’>上班</p> // 打工人 </div> </div> </div></template><script>export default { name: 'lookForMonth', data: () => { return { calendarData: [{label:'日'},{label: '一'}, {label:'二'},{label: '三'},{label: '四'},{label: '五'},{label: '六'}], //日历循环渲染数据 year: 0, //当前日期年 month: 0, //当前日期月数 date: 0, //当前日期号数 day: -1, //当前星期几 }; }, filters:{ }, computed: { // 根据当月日期详情更改日历表格高度 calendarStyle() { if (this.calendarData.length > 42) { return 'height: 701px;'; } else { return 'height: 601px;'; } } }, async created(){ // 获取当前日期数据 this.getNow(); // 获取当前月份一号的时间戳 let firstTime = +new Date(this.year,this.month-1,1,0,0,0) this.getCalendarDate(); // 给calendarData添加当月数据 }, mounted() { }, methods: { // 获取当前时间 getNow() { let now = new Date() this.year = +now.getFullYear() this.month = +now.getMonth() + 1 this.date = +now.getDate() this.day = +now.getDay() }, // 获取每个月的天数 monthDay(month) { if ([1,3,5,7,8,10,12].includes(month)) { return 31 } else if ([4,6,9,11].includes(month)) { return 30 } else if (month === 2) { // 判断当年是否为闰年 if ( (this.year % 4 === 0 && this.year % 100 !== 0) || this.year % 400 === 0 ) { return 29 } else { return 28 } } }, // 给calendarData添加当月数据 getCalendarDate() { // 获取当前月份一号星期几 let firstDay = new Date(this.year + '-' + this.month + '-' + '01').getDay(); this.calendarData = [{label:'日'},{label: '一'}, {label:'二'},{label: '三'},{label: '四'},{label: '五'},{label: '六'}]; let num = parseInt(firstDay); let nowDays = this.monthDay(this.month); let lastMonth = this.month - 1>0?this.month - 1:12; let lastDays = this.monthDay(lastMonth); // 循环添加上一个月数据 for (let i = 0; i < num; i++) { this.calendarData.push({label:lastDays - num + i + 1,color:’ash’}); } // 循环添加当月数据 for (let i = 0; i < nowDays; i++) { this.calendarData.push({label:i + 1}); } // 循环添加下一个月数据 if (this.calendarData.length % 7 !== 0) { let surplusDay = 7 - (this.calendarData.length % 7); for (let i = 0; i < surplusDay; i++) { this.calendarData.push({label:i + 1,color:’ash’}); } } this.loading = false }, // 将日期调上 dateUp() { this.month--; if (this.month <= 0) { this.year--; this.month = 12; } this.getCalendarDate(); // 给calendarData添加当月数据 }, // 将日期调下 dateDown() { this.month++; if (this.month > 12) { this.year++; this.month = 1; } this.getCalendarDate(); // 给calendarData添加当月数据 }, }};</script><style lang='scss' scoped>.lookForMonth_wrapper { padding: 20px; width: 701px; margin: auto;}.lookForMonth_top { margin-bottom: 20px; overflow: hidden; .selectTeacher { float: left; } .selectDate { height: 30px; line-height: 30px; float: right; display: flex; .upDownSelect { display: flex; flex-direction: column; margin-top: -2px; margin-left: 5px; .upDownSelect_item { width: 0; height: 0; border: 7px solid transparent; cursor: pointer; } .upDownSelect_item:nth-child(1) { border-bottom: 7px solid #666; margin-bottom: 5px; &:hover { border-bottom: 7px solid skyblue; } } .upDownSelect_item:nth-child(2) { border-top: 7px solid #666; &:hover { border-top: 7px solid skyblue; } } } }}/* 日历表样式=======================================↓ */.calendar { width: 701px; border-top: 1px solid #ccc; border-left: 1px solid #ccc; display: flex; flex-wrap: wrap; box-sizing: border-box; .calendar_item { box-sizing: border-box; width: 100px; height: 100px; border-right: 1px solid #ccc; border-bottom: 1px solid #ccc; text-align: center; display: flex; flex-direction: column; justify-content: center; align-items: center; &.date:hover{ background: #eee; } .status{ margin-top: 10px; &.textBlue{ color: blue; } &.textRed{ color: brown; } } .el-icon-edit-outline{ cursor: pointer; margin-left: 7px; } } .ash{ color: gainsboro; } .dateEdit{ margin-bottom: 10px; }}</style>

效果如下：
