工作需要,现有框架封装的日历无法满足需求,又找不到更好的插件的情况下,咋办??自己写个呗!
在这里插入图片描述
其实基本界面就这样了,和其他没啥区别。
但是既然要单独封装一个,那肯定有其他可扩展的地方,不然就没意义了
1、基本日历功能
2、可以自定义标题头部
3、可自定义顶部时间以及月份切换部分
4、日历单元格样式可以自定义
5、星期一栏可以自定义
6、可以在日历里面插入数据:这一点是最重要的,也是必须要自己封装的重要因素
封装为日历组件,直接引用即可。需要扩展其他功能,可以看组件里面的props哦,这是可以接收的参数。当然,如果用props不能满足的,那就看看里面的slot插槽部分咯。
props: { initDate:{ type:[String,Date,Number], default:()=>new Date() },//初始化日期 width:{ type:[String,Number], default:'100%' },//日历宽度 height:{ type:[String,Number], default:'100%' },//日历高度 calendarClass:String,//日历自定义样式类 titleClass:String,//年月标题自定义样式类 titleH:{ type:[String,Number], default:'35px' },//年月标题高度 titleBk:{ type:String, default:'#ffffff' },//年月标题颜色 bodyBk:{ type:String, default:'#ffffff' },//日历体背景 bodyClass:String,//日历体自定义样式 dateDefaultClass:String,//日期自定义默认类名 dateActivDateClass:String,//日期自定义选中类名 dateDisabledDateClass:String,//日期自定义不可见类名 titleDateConnector:String,//标题日期连接符 insertData:{ type:Array, default:()=>[] },//自定义拼接数据 weeks:{ type:Array, default:()=>['日','一','二','三','四','五','六'] },//周数据 dateProp:{ type:String, default:'date' },//自定义表示时间的字段 calenCellClass:String,//日历单元格自定义样式 firstRowCellClass:String,//日历第一行单元格自定义样式 firstColumCellClass:String,//日历第一列单元格自定义样式 cellBorder:Boolean,//是否有边框 cellTitleHeight:{ type:[Number,String], default:'40px' },//日历标题高度 cellTitleColor:{ type:String, default:'#333333' },//日历标题颜色 range:{ type:Array, default:()=>[] },//日期范围 },
在这里插入图片描述
插槽使用示例:
不熟悉插槽的伙伴可以去vue官网补补:https://cn.vuejs.org/v2/guide/components-slots.html
<calendar> <template #calendarTitle> <div class="rowStart calendarTitle"> <i class="el-icon-date yellow font20"></i> <strong class="font16" style="margin-left:5px;">日历标题</strong> </div> </template> <template #calendarTop="{currentYear,currentMonth,changeMonth}"> <div class="rowBtween canlendar-top-box"> <div class="rowStart year-back-box"> <strong class="font24">{{currentYear}}年{{currentMonth}}月</strong> <span class="blue back-today font14" @click="changeMonth(new Date())">返回今天</span> </div> <div class="change-month-box rowBtween"> <i class="el-icon-arrow-left el-icon blue" @click="changeMonth(0)"></i> <span></span> <i class="el-icon-arrow-right el-icon blue" @click="changeMonth(1)"></i> </div> </div> </template> </calendar>
其他不多说了,最后上代码。由于组件代码放在一个页面写重了点,因此分成了几个文件
所有data里面的变量,props,还有函数均有说明。
先看canlendar.vue
<template> <div class="custom-calendar" :style="{width:calendarWidth,height:calendarHeight}" :class="calendarClass"> <div class="calendar-topBox"> <slot name="calendarTitle"></slot> <slot name="calendarTop" :currentYear="currentYear" :currentMonth="currentMonth+1" :changeMonth="changeMonth"> <div class="calendar-title rowBtween" :style="{height:titleHeight,background:titleBk}" :class="titleClass"> <strong class="left">{{currentYear}}{{titleDateConnector || '年'}}{{currentMonth+1}}{{titleDateConnector ?
