这么多代码只要看一个地方就OK了，这里有三个DIV,分别是：
previousDiv 上一页ID
Copy after login
nextDiv 下一页ID
Copy after login
<strong>headerTitleDiv 日期容器ID 日期是需要放在input里的， ID为title日期的形式是day, input的type='text'，不可以是其它，否则，title不显示日期</strong>
Copy after login
<!--日期的容器--> <div class="headerDiv"> <div id="previousDiv" class="previousImgDiv"></div> <div id="nextDiv" class="unNextImgDiv" ></div> <div id="headerTitleDiv" class="titleDiv"><input id="title" type="text" style="background-color:#f0f0f0;border:none;font-size: 20px;text-align:center;"/></div> </div>
Copy after login
下面是JS的部分：
1、自定义变量
var previousDiv;var nextDiv;var headerTitleDiv;var title;//拼日期var currentWeek = theWeek();var defaultWeek = theWeek();var currentYear = theYear();var defautlYear = theYear();//监听上一页与下一页的点击事件var previousDivTapEvent;var nextDivTapEvent;
Copy after login
2、变量初始化：
$(document).ready(function(){ previousDiv = document.getElementById('previousDiv'); nextDiv = document.getElementById('nextDiv'); headerTitleDiv = document.getElementById('headerTitleDiv'); title = document.getElementById('title'); title.value = formartWeek(); //给前一页加点击事件，并监听它 previousDiv.addEventListener('tap', previousDivTapEvent); $(title).on('input', function(){ if(this.value.length == 0){ this.value.length = formartWeek(new Date()); }else{ if(checkCanDoNext()){ fetchDate(); return; } } }); } Copy after login
3、前一天监听事件（ fetchDate(); 日期与数据关联的方法，调用这个方法，可以取得与日期关联的数据 ）：
function previousDivTapEvent(){ resetNextEvent(); nextDiv.className = 'nextImgDiv'; title.value = getPreviousWeek(title.value); //fetchDate(); 日期与数据关联的方法，调用这个方法，可以取得与日期关联的数据 fetchDate();}Copy after login
4、下一天监听事件：
function nextDivTapEvent(){ resetPreviousEvent(); title.value = getNextWeek(); fetchDate(); if(checkCanDoNext){ nextDiv.removeEventListener('tap',nextDivTapEvent); return; }}Copy after login
5、获取上一周，并返回
function getPreviousWeek(){ //当前周减去一周currentWeek--; currentWeek--; if(currentWeek < 1){ currentYear--; currentWeek = 52; } return formartWeek();}Copy after login
6、获取下一周，并返回
function getNextWeek(){ //当前周加上一周主是下一周 currentWeek ++; //如果当前周大于52周，满一年，当前年加一年，新的一年，第一周 if(currentWeek > 52){ currentYear ++; currentWeek = 1; } return formartWeek();}Copy after login
7、判断，如果下一页有数据，则，可以点击进入下一页，如果没有数据，按钮不可点击
function checkCanDoNext(){ if(defaultWeek <= currentWeek && defautlYear <= currentYear){ title.value = formartWeek(); nextDiv.className = 'unNextImgDiv'; nextDiv.removeEventListener('tap',nextDivTapEvent); return true; }else{ resetNextEvent(); nextDiv.className = 'nextImgDiv'; return false; }}Copy after login
8、重置上一页的监听事件，先给按钮加一个图片class;
先删除原来的事件，再加上新的事件
function resetPreviousEvent(){ previousDiv.className = 'previousImgDiv'; previousDiv.removeEventListener('tap',previousDivTapEvent); previousDiv.addEventListener('tap',previousDivTapEvent);}Copy after login
9、重置下一页的监听事件，方法同上
function resetNextEvent(){ nextDiv.className = 'nextImgDiv'; nextDiv.removeEventListener('tap',nextDivTapEvent); nextDiv.addEventListener('tap',nextDivTapEvent);}Copy after login
10、格式化日期，以自定义方式返回
function formartWeek(){ return currentYear + "年 第 " + currentWeek + "周";}Copy after login
11、获取当前年份
function theYear(){ var now = new Date(); years = now.getFullYear(); return years;}Copy after login
12、获取当前周，并判断是否为闰年，针对2月的天数进行计算
function theWeek(){ var totalDays = 0; now = new Date(); years = now.getYear() if (years < 1000) years += 1900 var days = new Array(12); days[0] = 31; days[2] = 31; days[3] = 30; days[4] = 31; days[5] = 30; days[6] = 31; days[7] = 31; days[8] = 30; days[9] = 31; days[10] = 30; days[11] = 31; //判断是否为闰年，针对2月的天数进行计算 if (Math.round(now.getYear() / 4) == now.getYear() / 4) { days[1] = 29 } else { days[1] = 28 } if (now.getMonth() == 0) { totalDays = totalDays + now.getDate(); } else { var curMonth = now.getMonth(); for (var count = 1; count <= curMonth; count++) { totalDays = totalDays + days[count - 1]; } totalDays = totalDays + now.getDate(); } //得到第几周 var week = Math.round(totalDays / 7); return week;}Copy after login
以上为周日期的方法，需要注意以下几点：
- html中input的类型为text
<div id="headerTitleDiv" class="titleDiv"><input id="title" type="text" style="background-color:#f0f0f0;border:none;font-size: 20px;text-align:center;"/></div>
Copy after login
2. 前一页与后一页的点击事件中，可以加入与数据关联的方法，在点击进入下一页时，自动获取相应的数据
3. 给title添加input事件时，需要写一个判断：当前值 = 周日期的返回的方法。如果下一页有数据，才可以点击进入下一页：
$(title).on('input', function(){ if(this.value.length == 0){ this.value.length = formartWeek(new Date()); }else{ if(checkCanDoNext()){ fetchDate(); return; } } });Copy after login
