本文实例为大家分享了jQuery实现简单日历效果的具体代码，供大家参考，具体内容如下

日历效果如下图：

css部分：

<style> * { margin: 0; padding: 0; list-style: none; } .main { width: 380px; height: 370px; margin: 30px auto; position: relative; } button { width: 30px; height: 30px; border-radius: 50%; background: pink; font-size: 12px; text-align: center; line-height: 30px; border: none; position: absolute; color: #fff; outline: none; cursor: pointer; user-select: none; } .prev { top: 10px; left: 6%; } .next { top: 10px; right: 6%; } .nowTime { width: 90px; position: absolute; top: 15px; right: calc(50% - 45px); font-size: 14px; font-weight: bold; background: linear-gradient(to right, rgb(247, 149, 190), rgb(248, 204, 228)); -webkit-background-clip: text; color: transparent; } .container { width: 350px; margin: 50px auto; border: 1px solid #ccc; position: absolute; top: calc(50% - 190px); left: calc(50% - 175px); } .container ul:first-of-type { background: rgb(245, 195, 195); color: rgb(43, 40, 40); } .container ul { width: 350px; margin: 0 auto; display: flex; flex-wrap: wrap; text-align: center; } .container li { width: 50px; height: 50px; text-align: center; line-height: 50px; cursor: pointer; } .container li:not(.disabled):hover { background: rgb(255, 174, 208); } li.disabled { background: rgb(252, 238, 238); cursor: not-allowed; color: rgb(206, 206, 206); } li.active { background: rgb(255, 206, 214); }</style>

html部分：

<div class="main"> <button class="prev">上月</button> <p class="nowTime"></p> <button class="next">下月</button> <div class="container"> <ul> <li>日</li> <li>一</li> <li>二</li> <li>三</li> <li>四</li> <li>五</li> <li>六</li> </ul> <ul class="content"> </ul> </div></div>

js部分：

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script> $(function () { let allDays = 0 let now = new Date() let global_month = now.getMonth() + 1 let global_year = now.getFullYear() let today = now.getDate() $('.prev').click(function () { now.setMonth(now.getMonth() - 1) calendar() }) $('.next').click(function () { now.setMonth(now.getMonth() + 1) calendar() }) function calendar() { $('.content').empty() let month = now.getMonth() + 1 let year = now.getFullYear() //得到每个月多少天 switch (month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: allDays = 31 break; case 4: case 6: case 9: case 11: allDays = 30 break; default: //判断闰年 得到二月份的天数 if ((year % 4 === 0 && year % 100 !== 0) || year % 400 === 0) { allDays = 29 } else { allDays = 28 } break; } //获取当前月份有多少天 生成相应个数的li for (let i = 1; i <= allDays; i++) { let li = $('<li/>').text(i) //给对应今天的li添加高亮效果 if (i === today && year === global_year && month === global_month) li.addClass('active') $('.content').append(li) } //思路：每个月一号前面空几个 空的个数为周几就空几个 now.setDate(1) //将时间设置成本月的一号 let firstDay = now.getDay() // 获取一号是周几 for (let i = 0; i < firstDay; i++) { // 循环次数为对应的是周几 now.setDate(now.getDate() - 1) //每循环一次 日期往前倒一天 let li = $('<li/>').text(now.getDate()).addClass('disabled') //生成相对应的空格 $('.content').prepend(li) } now.setDate(now.getDate() + firstDay) //将时间设置回当前时间 否则影响后面时间的获取 now.setDate(allDays) //思路：每个月最后一天后面空几个 空的个数为6减周几就空几个 now.setDate(allDays) //将时间设置成每月最后一天 let lastDay = 6 - now.getDay() //最后空的个数 for (let i = 0; i < lastDay; i++) { now.setDate(now.getDate() + 1) //每循环一次 日期往后加一天 let li = $('<li/>').text(now.getDate()).addClass('disabled') //生成相对应的空格 $('.content').append(li) } now.setDate(now.getDate() - lastDay) //将时间设置回当前时间 否则影响后面时间的获取 now.setDate(1) $('.nowTime').html(now.getFullYear() + '年' + (now.getMonth() + 1) + '月') } calendar() })</script>
