使用Vue实现简单日历效果
使用Vue实现简单的日历,供大家参考,具体内容如下
原理分析:
1.获取当前时间
2.显示当前时间
3.点击增加和减少月份
4.大月和小月的天数
效果演示
初始样式(显示现在的日期时间)
增加一个月
在程序开始之前一定注意:
引入Vue.js架包
代码演示
Body内容
<script type="text/x-template" id="calendar"> <!-- 年份--> <div id="year"> <!--月份 --> <div class="month"> <ul> <li class="arrow" @click="pickPre(currentYear,currentMonth)">❮</li> <li class="year-month" @click="pickYear(currentYear,currentMonth)"> <span class="choosen-year" style="color:blue">{{ currentYear }}</span> <span class="choosen-month" style="color:blue">{{ currentMonth }}月</span> </li> <li class="arrow" @click="pickNext(currentYear,currentMonth)">❯</li> </ul> </div> <!-- 星期 --> <ul class="weekdays"> <li>一</li> <li>二</li> <li>三</li> <li>四</li> <li>五</li> <li style="color:red">六</li> <li style="color:red">日</li> </ul> <!-- 日期 --> <ul class="days"> <!-- 循环--> <li v-for="dayobject in days"> <!--本月--> <span v-if="dayobject.day.getMonth()+1 != currentMonth" class="other-month">{{ dayobject.day.getDate() }}</span> <!--判断天数是否正确--> <span v-else> <!--今天--> <span v-if="dayobject.day.getFullYear() == new Date().getFullYear() && dayobject.day.getMonth() == new Date().getMonth() && dayobject.day.getDate() == new Date().getDate()" class="active">{{ dayobject.day.getDate() }}</span> <span v-else>{{ dayobject.day.getDate() }}</span> </span> </li> </ul> </div> </script> <div id="app"> <calendar></calendar> </div>
CSS样式
* { margin: 0; padding: 0; } /*日历*/ #calendar { width: 98%; border: 2px solid #A4A7B0; height: 335px; margin-left: 0.5%; } .month { width: 92%; height: 48px; border: 2px solid #FFFFFF; margin-left: 3%; margin-top: 20px; } .month ul { margin: 0; padding: 0; display: flex; margin-top: 11px; justify-content: space-between; } .year-month { flex-direction: column; align-items: center; justify-content: space-around; } .choosen-year { padding: 0 20px; font-size: 16px; font-weight: 200; } .choosen-month { text-align: center; font-size: 16px; font-weight: 200; } .arrow { width: 3%; height: 25px; } .arrow1 { background: url(left.png) no-repeat 0 0 /100% 100%; margin-left: 44px; } .arrow2 { background: url(right.png) no-repeat 0 0 /100% 100%; margin-right: 44px; } .month ul li { color: #999; font-size: 20px; text-transform: uppercase; letter-spacing: 3px; list-style: none; } .weekdays { margin: 0; color: #FFFFFF; background: #A4A7B0; width: 96.6%; margin-top: 26px; height: 34px; line-height: 34px; margin-left: 2.2%; } .weekdays li { display: inline-block; text-align: center; color: #11616f; font-size: 14px; font-weight: 100; width: 12.7%; } .days { padding: 0; margin: 0; display: flex; flex-wrap: wrap; justify-content: space-around; } .days li { list-style-type: none; display: inline-block; width: 14.2%; text-align: center; padding-bottom: 3px; padding-top: 7px; font-size: 12.78px; color: rgb(14, 220, 235); font-weight: 200; } .days li span span { height: 29.5px; width: 27px; line-height: 29.5px; display: inline-block; } .days li .class-30 { background: url(bg_30.png) no-repeat 0 0 /100% 100%; } .days li .class-60 { background: url(bg_60.png) no-repeat 0 0 /100% 100%; } .days li .class-3060 { background: url(bg_3060.png) no-repeat 0 0 /100% 100%; } .days li .other-month { padding: 5px; color: #84a8ae; }
Vue.js内容
Vue.component("calendar", { template: "#calendar", data: function() { return { currentDay: 1, currentMonth: 1, currentYear: 1970, currentWeek: 1, days: [], } }, created() { let that = this; that.initData(null); }, methods: { initData: function(cur) { let that = this; let leftcount = 0; let date; if (cur) { date = new Date(cur); } else { let now = new Date(); let d = new Date(that.formatDate(now.getFullYear(), now.getMonth(), 1)); d.setDate(35); date = new Date(that.formatDate(d.getFullYear(), d.getMonth() + 1, 1)); } that.currentDay = date.getDate(); that.currentYear = date.getFullYear(); that.currentMonth = date.getMonth() + 1; that.currentWeek = date.getDay(); // 1...6,0 if (that.currentWeek == 0) { that.currentWeek = 7; } let str = that.formatDate(that.currentYear, that.currentMonth, that.currentDay); that.days.length = 0; //初始化 for (let i = that.currentWeek - 1; i >= 0; i--) { let d = new Date(str); d.setDate(d.getDate() - i); let dayobject = {}; dayobject.day = d; that.days.push(dayobject); } for (let i = 1; i <= 35 - that.currentWeek; i++) { let d = new Date(str); d.setDate(d.getDate() + i); let dayobject = {}; dayobject.day = d; that.days.push(dayobject); } }, pickPre: function(year, month) { let that = this; let d = new Date(that.formatDate(year, month, 1)); d.setDate(0); that.initData(that.formatDate(d.getFullYear(), d.getMonth() + 1, 1)); }, pickNext: function(year, month) { let that = this; let d = new Date(that.formatDate(year, month, 1)); d.setDate(35); that.initData(that.formatDate(d.getFullYear(), d.getMonth() + 1, 1)); }, pickYear: function(year, month) { alert(year + "," + month); }, // 返回 类似 2016-01-02 格式的字符串 formatDate: function(year, month, day) { let y = year; let m = month; if (m < 10) m = "0" + m; let d = day; if (d < 10) d = "0" + d; return y + "-" + m + "-" + d }, } }) let vm = new Vue({ el: '#app', })
到此程序结束。
