微信小程序可滑动周日历组件，供大家参考，具体内容如下
看网上周日历组件比较少，自己弄了一个，和大家分享一下。
如果样式变形，请检查是否有共用样式起冲突
展示一下效果图
在components组件文件夹下新建calendarWeek文件夹
直接上代码吧：
index.wxml
<!--components/calendarWeek/index.wxml-->
<!-- 日历 -->
<view class="date-choose shrink border-bottom10">
<picker mode="date" bindchange="tiaotime"><view class="data-month">{{dateYear}}{{dateMonth}}</view></picker>
<swiper class="date-choose-swiper" circular="true" indicator-dots="{{false}}" current="{{swiperCurrent}}" bindchange="dateSwiperChange">
<block wx:for="{{dateList}}" wx:for-item="date" wx:key="date.id">
<swiper-item class="swiper-item">
<view class="weekday">
<block wx:for-item="weekday" wx:for="{{dateListArray}}" wx:key="{{index}}">
<text class="week">{{weekday}}</text>
</block>
</view>
<view class="dateday">
<block wx:for="{{date.days}}" wx:for-item="day" wx:key="{{day.id}}">
<!-- <view>{{day.ids}}</view> -->
<view class="day" id="{{day.id}}" bindtap="chooseDate" >
<text class="{{dateCurrentStr==day.id" >{{day.day}}</text>
</view>
</block>
</view>
</swiper-item>
</block>
</swiper>
</view>

index.js
// components/calendarWeek/index.js
var utils = require('./util.js')

this.setData({
dateList: []
})
this.initDate(-5, 2, d); // 日历组件程序 -4左表示过去4周 右1表示过去一周
},
onShow: function (e) {
wx.getSystemInfo({
success: (res) => {
this.setData({
windowHeight: res.windowHeight,
windowWidth: res.windowWidth,
});
}
});
},
// 日历组件部分
// ----------------------------
initDate(left, right, d) {
var month = utils.addZero(d.getMonth() + 1),

for (var i = left; i <= right; i++) {

},
// 获取这周从周日到周六的日期
calculateDate(_date) {
var first = utils.FirstDayInThisWeek(_date);
var d = {
'month': first.getMonth() + 1,
'days': [],
};
for (var i = 0; i < 7; i++) {

// 获得日期字符串
getDateStr: function (arg) {

// 点击日历某日
chooseDate(e) {
var str = e.currentTarget.id;
// console.log(str);
this.setData({ dateCurrentStr: str });
this.triggerEvent('mydata', { data: str })
},
}
})
要引入util.js
// 时间格式转换 yyyy/mm/dd
function formatTime(date) {
var year = date.getFullYear()
var month = date.getMonth() + 1
var day = date.getDate()
var hour = date.getHours()
var minute = date.getMinutes()
var second = date.getSeconds()
return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}
// 时间格式转换 yyyy－mm－dd
function formatTime2(date) {
var year = date.getFullYear()
var month = date.getMonth() + 1
var day = date.getDate()
var hour = date.getHours()
var minute = date.getMinutes()
var second = date.getSeconds()
return [year, month, day].map(formatNumber).join('-')
}
function formatDate(date, split) {
var year = date.getFullYear()
var month = date.getMonth() + 1
var day = date.getDate()
return [year, month, day].map(formatNumber).join(split || '')
}
// 两位数自动补零
function formatNumber(n) {
n = n.toString()
return n[1] " ")[1];
return typeStr.substr(0, typeStr.length - 1).toLowerCase();
}
module.exports = {
formatTime: formatTime,
formatDate: formatDate,
formatTime2,
DateAddDay: DateAddDay,
FirstDayInThisWeek: FirstDayInThisWeek,
type: Type,
addZero: formatNumber,
}
调用组件
//json文件调用
"usingComponents": {
"calendarMonth": "../../components/calendarWeek/index"
}
页面调用组件
//mydata触发的点击日期时触发的事件 可获取当前点击的日期 <calendarMonth bindmydata="mydata"></calendarMonth>
当前页面js
//js里的事件
mydata(e){ //可获取日历点击事件
let data = e.detail.data
console.log(data)
}
