js日历控件开发
最终日历控件实例代码地址：http://www.oschina.net/code/snippet_2352644_55198javascript
什么是日历控件？效果什么样子？这是一个网站上的在线演示效果：http://www.jq22.com/yanshi5303css
咱们开发的最终实现就是大体这个样子，咱们简单把效果的逻辑简单概述：html
一个inputjava
咱们点击input会弹出日历控件node
咱们点击日历控件的日期就会显示到input中express
日历控件的年月可更改选择cookie
能够清除input的日期app
咱们这样就简单的概述了这个效果，下面咱们就会出现下面的疑问？函数
在js中，时期是怎么获取和设置！测试
此次的实例开发讲解，会分为2篇，日历控件实例相对来讲要先有准备知识的了解，咱们在之前的博客中只有在cookie中简单介绍过date对象的gmt转化方法。
一.date对象基本知识
1.date对象建立
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>date</title> <style type="text/css"> </style> </head> <body> <input type="text" id="date" value="日历控件"/> </body> <script type="text/javascript"> var dateObj = new Date(); alert(typeof dateObj); </script> </html>
经过Date类咱们直接可建立date对象，在建立对象，不设置参数的状况下，默认的date对象使用当前时间作参数。
好比今天是2016/4/5那么日期对象的年 月 日分别就是2016 4 5。
2.date对象读取
读取就是拿，拿到日期对象中咱们想要的具体内容，好比：年，月，日，时分秒，等等等。
咱们获取年月日：
var dateObj = new Date();
alert("年："+dateObj.getFullYear());
alert("月："+dateObj.getMonth());
alert("日："+dateObj.getDate());
日期对象月是返回0-11，因此咱们拿到的值+1才是真实月份。
获取周：
var dateObj = new Date();
alert("周："+dateObj.getDay());
周的特殊之处就是星期日的处理，返回是0。
获取时分秒：
var dateObj = new Date();
alert("时："+dateObj.getHours());
alert("分："+dateObj.getMinutes());
alert("秒："+dateObj.getSeconds());
这里的返回值都是从0开始，0其实就是对应表明了24小时，60分钟，60秒，和周相似。
获取毫秒：
更加精确的时间，不在很特殊时咱们也不会拿去的，和秒的关系 1秒=1000毫秒
var dateObj = new Date();
alert("毫秒："+dateObj.getMilliseconds());
同理，返回0表明1000毫秒值。
返回 1970 年 1 月 1 日至今的毫秒数：
这个就是unix时间戳的使用了，咱们会拿到距离时间：
var dateObj = new Date();
alert("距离 1970 年 1 月 1 日的毫秒数："+dateObj.getTime());
咱们采用默认参数，date对象就是当前时间，获取就是这个时间距离1970/1/1的毫秒数。
转为GMTString时间：
这个就是咱们cookie过时时间的使用了：
var dateObj = new Date();
alert("GMTString："+dateObj.toUTCString());
这实际上是一种日期格式，cookie你必须用这种格式，咱们使用的方法是如今推荐的，toGMTString()不被推荐使用。
其实除了这些，还有根据世界时间的返回，咱们这里就不在介绍了。
3.date对象设置
几乎全部的获取操做，都会对应设置操做，咱们建立了date对象，对象包含各类日期信息（年，月，日等），这些信息其实都是来自new时的参数，咱们默认采用当前。
咱们还能修改对象中的各类信息，修改了咱们在获取，就是拿到修改的信息了。
咱们设置年月日：
var dateObj = new Date();
alert("默认年："+dateObj.getFullYear());
alert("默认月："+dateObj.getMonth());
alert("默认日："+dateObj.getDate());
dateObj.setFullYear(2008);
dateObj.setMonth(8);
dateObj.setDate(8);
alert("修改后年："+dateObj.getFullYear());
alert("修改后月："+dateObj.getMonth());
alert("修改后日："+dateObj.getDate());
咱们先获取默认参数的时间，而后设置指定的年月日，获取时就知道确实修改了对应信息。
其余的时分秒相似不作介绍。
根据距离 1970 年 1 月 1 日至今的毫秒数设置日期对象：
与gettime正好相反的操做，get是拿到毫秒，set是根据毫秒设置修改date的全部信息。
var dateObj = new Date();
alert("默认年："+dateObj.getFullYear());
alert("默认月："+dateObj.getMonth());
alert("默认日："+dateObj.getDate());
var now=dateObj.getTime();//获取1970毫秒
var prev=now-24*60*60*1000;//获取昨天距离1970的毫秒，减去一天的毫秒数，一天是24小时，1小时60分钟，1分钟60秒，1秒是1000毫秒
dateObj.setTime(prev);
alert("修改后年："+dateObj.getFullYear());
alert("修改后月："+dateObj.getMonth());
alert("修改后日："+dateObj.getDate());
二.date对象小实例
仅仅知道了date的建立，设置和获取是不足以让咱们灵活运用它，咱们下面经过开发多个小实例，增强咱们对date的使用和了解。
实例1：页面今日日期显示
在一些网站，咱们会看到显示今天的年月日和星期几信息，咱们怎么把这些信息显示到页面当中？
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>date</title>
<style type="text/css">
</style>
</head>
<body>
<input type="text" id="date" value="日历控件"/>
<div id="show"></div>
</body>
<script type="text/javascript">
var show=document.getElementById("show");
var dateObj = new Date();
var year=dateObj.getFullYear();
var month=dateObj.getMonth();//0是12月
var day=dateObj.getDate();
var week=dateObj.getDay();//0是星期日
show.innerHTML="当前日期"+year+"年"+month+"月"+day+"日"+"星期"+week;
</script>
</html>
截图：
经过截图，咱们看到的已知问题就是月份，月份是要+1的，由于返回值是0-11表明1-12月，一个隐藏问题就是星期，若是是星期日，返回是0；对于转化映射的处理，咱们能够采用js的switch case语句。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>date</title>
<style type="text/css">
</style>
</head>
<body>
<input type="text" id="date" value="日历控件"/>
<div id="show"></div>
</body>
<script type="text/javascript">
var show=document.getElementById("show");
var dateObj = new Date();
var year=dateObj.getFullYear();
var month=toyear(dateObj.getMonth());//0是12月
var day=dateObj.getDate();
var week=toweek(dateObj.getDay());//0是星期日
show.innerHTML="当前日期"+year+"年"+month+"月"+day+"日"+week;
function toweek(week){
switch(week)
{
case 0:
return "星期日";
break;
case 1:
return "星期一";
break;
case 2:
return "星期二";
break;
case 3:
return "星期三";
break;
case 4:
return "星期四";
break;
case 5:
return "星期五";
break;
case 6:
return "星期六";
break;
default:
};
};
function toyear(month){
switch(month)
{
case 0:
return "1";
break;
case 1:
return "2";
break;
case 2:
return "3";
break;
case 3:
return "4";
break;
case 4:
return "5";
break;
case 5:
return "6";
break;
case 6:
return "7";
break;
case 7:
return "8";
break;
case 8:
return "9";
break;
case 9:
return "10";
break;
case 10:
return "11";
break;
case 11:
return "12";
break;
default:
};
};
</script>
</html>
截图：
达到咱们想要的结果。
实例2：简单时钟
一个时钟，就会包含时分秒这些信息，而且会动态变化，咱们利用常用的setinterval函数，而且把间隔设置为1000也就是1秒就正好知足动态变化的需求：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>date</title>
<style type="text/css">
</style>
</head>
<body>
<input type="text" id="date" value="日历控件"/>
<div id="show"></div>
</body>
<script type="text/javascript">
var show=document.getElementById("show");
var dateObj = new Date();
var hour=tohour(dateObj.getHours());
var minu=tominu(dateObj.getMinutes());
var sec=tosec(dateObj.getSeconds());
show.innerHTML=hour+"时"+minu+"分"+sec+"秒";
setInterval(function(){
dateObj = new Date();
hour=tohour(dateObj.getHours());
minu=tominu(dateObj.getMinutes());
sec=tosec(dateObj.getSeconds());
show.innerHTML=hour+"时"+minu+"分"+sec+"秒";
},1000);
function tohour(t){
if(t==0){
return 24;
}else{
return t;
};
};
function tominu(t){
if(t==0){
return 60;
}else{
return t;
};
};
function tosec(t){
if(t==0){
return 60;
}else{
return t;
};
};
</script>
</html>
效果截图：
三.本月日历
1.静态结构建立
今天是2016年4月5日，咱们想要把4月的全部信息显示出来，而且把5日特殊标记，大概样子是这样的：
最上面的月和年是比较简单的，咱们直接获取就能够了，下面的内容就比较麻烦了，咱们分析发现，
1.本月的信息会所有显示，
2.并且1号这一天根据它所在的周，要在前面出现留空位置，
3.5这个就是当前日，加入特殊标记。
咱们先不考虑动态处理问题，咱们先把静态结构完成，用写死的形式把这个效果写出来：

var dateObj = new Date();

var month=toyear(dateObj.getMonth());//0是12月

oyear.innerHTML=year+"年";
function toyear(month){

case 10: return "11"; break;
case 11: return "12"; break;
default:
};
};
};
</script>
</html>
2.动态处理日期
咱们把日的显示写死，咱们只要利用动态处理，就能够完成动态建立了，咱们要想完成留空的处理，咱们要获取的信息包含以下：
1.本月1日是星期几？若是是星期5，也就是返回了5，那么留空就是5,是星级1，返回1留空就是1
2.获取这个月日的总个数，这个简单1 3 5 7 8 10 12哈哈，31天永不差，需注意闰年，用做循环建立全部的日
3.返回今日，好比这个例子返回5，再循环中咱们要判断等于5的加入特殊处理
如何获取本月1日信息？
咱们只要先建立一个默认的日期对象，而后利用setdate(1)把对象的日设置为1其实就获取了本月1号的信息，而后然获取所在的周，就首先拿到了留空个数：
//获取本月1号的周值 var oneyear = new Date(); oneyear.setDate(1); var oneweek=oneyear.getDay(); alert(oneweek)
很是的完美，下面咱们实现2，也就是拿到本月总的日数，基本规律就是口诀，不过咱们先判断一把是不是闰年，要遇到2月特殊处理：
判断闰年条件①：非整百年数除以4，无余为闰，有余为平；②整百年数除以400，无余为闰有余平。
//闰年判断函数
function isLeapYear(year) {
if( (year % 4 == 0) && (year % 100 != 0 || year % 400 == 0)){
return true;
}else{
return false;
};
};
咱们测试输出总日数：
//本月总日数
var alld=alldays(year,dateObj.getMonth());
alert(alld);
//获取本月总日数方法
function alldays(year,month){
if(isLeapYear(year)){//闰年
switch(month) {
case 0: return "31"; break;
case 1: return "29"; break; //2月
case 2: return "31"; break;
case 3: return "30"; break;
case 4: return "31"; break;
case 5: return "30"; break;
case 6: return "31"; break;
case 7: return "31"; break;
case 8: return "30"; break;
case 9: return "31"; break;
case 10: return "30"; break;
case 11: return "31"; break;
default:
};
}else{//平年
switch(month) {
case 0: return "31"; break;
case 1: return "28"; break; //2月
case 2: return "31"; break;
case 3: return "30"; break;
case 4: return "31"; break;
case 5: return "30"; break;
case 6: return "31"; break;
case 7: return "31"; break;
case 8: return "30"; break;
case 9: return "31"; break;
case 10: return "30"; break;
case 11: return "31"; break;
default:
};
};
};
//闰年判断函数
function isLeapYear(year){
if( (year % 4 == 0) && (year % 100 != 0 || year % 400 == 0)){
return true;
}else{
return false;
};
};
最后一个重要信息，当前日：
//当前是几 var nowd=dateObj.getDate(); alert(nowd);
准备工做完成，咱们初始化显示咱们的时间：
//初始化显示本月信息
init(oneweek,alld,nowd);
//初始化日期显示方法
function init(oneweek,alld,nowd){
for(var i=1;i<=oneweek;i++){//留空
var eday=document.createElement("div");
eday.innerHTML="";
con.appendChild(eday);
};
for(var i=1;i<=alld;i++){//正常区域
var eday=document.createElement("div");
if(i==nowd){
eday.innerHTML=i;
eday.className="now";
con.appendChild(eday);
}else{
eday.innerHTML=i;
con.appendChild(eday);
};
};
};
咱们把全部代码整理，看到下面截图效果：
效果没有变，不过内容是经过js添加：

四.动态日历
什么是动态，就是能够利用上一页或者下一页查看上一个月，下一个月，上上一个月的日历信息！
咱们把本身程序进一步优化，让更多的获取来自函数：
通过一顿的修正，咱们把近乎全部获取操做都经过new的date实现：

咱们如何检验结果的活跃性呢？咱们只要把new date的月份作一次修改，就能够检测结果了：
设置为上一个月，看结果：
有些完美了是否是，咱们试想若是这中设置方式结合页面处理，是否是就成就了咱们的实现，。
五.加入上一月下一月
咱们先修改结构，加入上一月和下一月的按钮：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

<style type="text/css">

var eday=document.createElement("div");
eday.innerHTML="";
con.appendChild(eday);
};
for(var i=1;i<=alld;i++){//正常区域
var eday=document.createElement("div");
if(i==nowd){
eday.innerHTML=i;
eday.className="now";
con.appendChild(eday);
}else{
eday.innerHTML=i;
con.appendChild(eday);
};
};
};
//获取本月1号的周值
function oneyearoneday(dateObj){
var oneyear = new Date();
var year=dateObj.getFullYear();
var month=dateObj.getMonth();//0是12月
oneyear.setFullYear(year);

case 11: return "31"; break;

switch(month) {
case 0: return "31"; break;

case 3: return "30"; break;

};
};
};
</script>
</html>
效果截图：
如今咱们就要进一步处理，就是点击上一个月或者一下月修改日的显示，而且上面的年月也要修改，不断上一月咱们会到2015年甚至更之前。
六.开发上一月下一月控制程序
拿到：
var prevmonth=document.getElementById("prevmonth");
var nextmonth=document.getElementById("nextmonth");
事件就是单击事件了，咱们简单处理：
prevmonth.onclick=function(){//上一月
};
nextmonth.onclick=function(){//下一月
};
贪多嚼不烂，咱们先把上一月处理好，再去看下一月：
上一月，就和上篇博客最后同样，咱们只要把月设置为当前-1；
//动态控制
prevmonth.onclick=function(){//上一月
var ddm=dateObj.getMonth()-1;
dateObj.setMonth(ddm);
omonth.innerHTML=toyear(dateObj)+"月";
remove();
oneweek=oneyearoneday(dateObj);
alld=alldays(dateObj);
nowd=nowday(dateObj);
init(oneweek,alld,nowd);
};
固然，二次赋值前先清除：
function remove(){
con.innerHTML="";
};
咱们还要加个判断限制，当处在1月，在点击上一月，年要发生变化，月变为上一年的12月：
prevmonth.onclick=function(){//上一月
var ddm=null;
var ddy=null;
if((dateObj.getMonth()-1)==-1){
ddm=11;
ddy=dateObj.getFullYear()-1;
}else{
ddm=dateObj.getMonth()-1;
ddy=dateObj.getFullYear();
};
dateObj.setFullYear(ddy);
dateObj.setMonth(ddm);
omonth.innerHTML=toyear(dateObj)+"月";
remove();
oneweek=oneyearoneday(dateObj);
alld=alldays(dateObj);
nowd=nowday(dateObj);
init(oneweek,alld,nowd);
};
看如今所有代码：

九.与输入文本框绑定
个人时间控件默认是不可见的在input获取焦点时才会显示：
默认隐藏，最简单就是直接none掉，input获取焦点咱们blcok，位置利用绝对定位，获取input相对页面的left和top赋值给box便可：
