wxml

   <view class="dateView">
    <image class="dateLeft" bindtap="prevWeek" src="../../res/imgs/dateLeft.png"></image>
    <view>{{dateStart}} 至 {{dateEnd}}</view>
    <image class="dateRight" bindtap="nextWeek" src="../../res/imgs/dateRight.png"></image>
   </view>

wxss

.dateView{
 padding:0 32rpx;
 height:98rpx;
 display: flex;
 align-items: center;
 background:#fff;
}
.dateView>image{
 width:50rpx;
 height:50rpx;
}
.dateView>view{
 flex: 1;
 text-align: center;
 color:#333;
 font-size: 34rpx;
}

js

const GetPeriod = require("../../utils/getperiod.js");
Page({

 /**
  * 页面的初始数据
  */
 data: {
  currentTab: 1,
  dateStart:'2019-10-16',
  dateEnd: '2019-10-16',
 },

 /**
  * 生命周期函数--监听页面加载
  */
 onLoad: function(options) {
  let that = this;
 
  that.getWeekStartDate(0)
 },

 //获取本周的开始日期
 getWeekStartDate(numDay) {
  let that = this;
  this.now = new Date();
  this.nowYear = this.now.getYear(); //当前年 
  this.nowMonth = this.now.getMonth(); //当前月 
  this.nowDay = this.now.getDate(); //当前日 
  this.nowDayOfWeek = this.now.getDay(); //今天是本周的第几天 
  this.nowYear += (this.nowYear < 2000) ? 1900 : 0;
  let dateStart = GetPeriod.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay - this.nowDayOfWeek + 1 + numDay));
  let dateEnd = GetPeriod.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay - this.nowDayOfWeek + 7 + numDay));
  // console.log(dateStart)
  // 获取今天日期
  let now = GetPeriod.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay));
  now = now.replace(/-/g, "/");
  now = now.substring(5);
  this.setData({
   dateStart: dateStart,
   dateEnd: dateEnd,
   now: now,
   dates: now,
  })
  // 初始化数据(历史纪录)
  var timestamp = Date.parse(new Date(this.data.dateStart));
  timestamp = timestamp / 1000;
  // console.log(timestamp);
  that.setData({
   timestamp: timestamp
  })  
 },

// 点击上一周
prevWeek: function(e) {
this.data.num = this.data.num - 7;
this.getWeekStartDate(this.data.num);
},
// 点击下一周
nextWeek: function(e) {
this.data.num = this.data.num + 7;
this.getWeekStartDate(this.data.num);
 },
})
function constructor1 (){
 this.now = new Date();
 this.nowYear = this.now.getYear(); //当前年 
 this.nowMonth = this.now.getMonth(); //当前月 
 this.nowDay = this.now.getDate(); //当前日 
 this.nowDayOfWeek = this.now.getDay(); //今天是本周的第几天 
 this.nowYear += (this.nowYear < 2000) ? 1900 : 0;
}
//格式化数字
function formatNumber (n) {
 n = n.toString()
 return n[1] ? n : '0' + n
}
//格式化日期
function formatDate(date){
 let myyear = date.getFullYear();
 let mymonth = date.getMonth() + 1;
 let myweekday = date.getDate();
 return [myyear, mymonth, myweekday].map(this.formatNumber).join('-');
}
//获取某月的天数
function getMonthDays (myMonth) {
 let monthStartDate = new Date(this.nowYear, myMonth, 1);
 let monthEndDate = new Date(this.nowYear, myMonth + 1, 1);
 let days = (monthEndDate - monthStartDate) / (1000 * 60 * 60 * 24);
 return days;
}
//获取本季度的开始月份
function getQuarterStartMonth (){
 let startMonth = 0;
 if (this.nowMonth < 3) {
  startMonth = 0;
 }
 if (2 < this.nowMonth && this.nowMonth < 6) {
  startMonth = 3;
 }
 if (5 < this.nowMonth && this.nowMonth < 9) {
  startMonth = 6;
 }
 if (this.nowMonth > 8) {
  startMonth = 9;
 }
 return startMonth;
}
//获取本周的开始日期
function getWeekStartDate() {
 return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay - this.nowDayOfWeek + 1));
}
//获取本周的结束日期
function getWeekEndDate() {
 return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay + (6 - this.nowDayOfWeek + 1)));
}
//获取今天的日期
function getNowDate() {
 return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay));
}
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(':')
}
module.exports = {
 formatNumber: formatNumber,
 constructor1: constructor1,
 formatDate: formatDate,
 getMonthDays: getMonthDays,
 getQuarterStartMonth: getQuarterStartMonth,
 getWeekStartDate: getWeekStartDate,
 getNowDate: getNowDate,
 getWeekEndDate: getWeekEndDate,
 formatTime: formatTime
}

效果如下

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持前端开发者。
