之前在上家公司做過一個公司人員考勤的東西,裡面需要用到日曆,當時自己用vue隨便寫了一個,比較簡單,刪掉了其他功能的程式碼,只留下日曆,直接看程式碼
<template> <div class="lookForMonth_wrapper"> <div class="lookForMonth_top"> <div class="selectDate"> <div>{{year}} 年 {{month}} 月</div> <div class="upDownSelect"> <div class="upDownSelect_item" @click="dateUp"></div> <div class="upDownSelect_item" @click="dateDown"></div> </div> </div> </div> <div class="calendar" :style="calendarStyle"> <div v-for="(item,index) in calendarData" class="calendar_item" :key='index' :class="{ash:item.color==='ash',date:index>6&&item.color!=='ash'}"> <p class="dateEdit">{{item.label}}<i class="el-icon-edit-outline" 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"}],//日曆迴圈渲染資料 year: 0,//當前日期年 month: 0,//當前日期月數 date: 0,//當前日期號數 day: -1,//當前星期幾 }; },filters:{ },computed: { // 根據當月日期詳情更改日曆表格高度 calendarStyle() { if (this.calendarData.length > 42) { return "height: 701px;"; } else { return "height: 601px;"; } } },async created(){ // 獲取當前日期資料 this.getNow(); // 獲取當前月份一號的時間戳 let firstTime = +new Date(this.year,this.month-1,1,0) this.getCalendarDate(); // 給calendarData添加當月資料 },mounted() { },methods: { // 獲取當前時間 getNow() { let now = new Date() this.year = +now.getFullYear() this.month = +now.getMonth() + 1 this.date = +now.getDate() this.day = +now.getDay() },// 獲取每個月的天數 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) { // 判斷當年是否為閏年 if ( (this.year % 4 === 0 && this.year % 100 !== 0) || this.year % 400 === 0 ) { return 29 } else { return 28 } } },// 給calendarData添加當月資料 getCalendarDate() { // 獲取當前月份一號星期幾 let firstDay = new Date(this.year + "-" + this.month + "-" + "01").getDay(); this.calendarData = [{label:"日"},{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); // 迴圈新增上一個月資料 for (let i = 0; i < num; i++) { this.calendarData.push({label:lastDays - num + i + 1,color:'ash'}); } // 迴圈添加當月資料 for (let i = 0; i < nowDays; i++) { this.calendarData.push({label:i + 1}); } // 迴圈新增下一個月資料 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 },// 將日期調上 dateUp() { this.month--; if (this.month <= 0) { this.year--; this.month = 12; } this.getCalendarDate(); // 給calendarData添加當月資料 },// 將日期調下 dateDown() { this.month++; if (this.month > 12) { this.year++; this.month = 1; } this.getCalendarDate(); // 給calendarData添加當月資料 },} }; </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; } } } } } /* 日曆表樣式=======================================↓ */ .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:
