js日历功能对象

  需求产生问题:本来想在网上找个js代码,可是发现要么太复杂,要么不好控制,要么兼容性不好......

  问题分析: 发现不是优秀的就是最好的.... 适合自己的就是最好的。

  问题解决: 决定自己写一个日历 功能。

  代码呈现:

  日历主程序

  

复制代码 代码如下:

  var calendar={

  STR:function(){with(this.data)return ""+Y+"年,"+M+"月,"+D+"号,星期"+WN[W];},

  V:function(o,spli,sx){with(this)return o[sx]=""+data.Y+spli+data.M+spli+data.D},

  T:function(){with(this)return data.TABLE},

  dnY:function(){with(this){calendarChange(data.Y+1,data.M-1,data.D)}},

  dnM:function(){with(this){calendarChange(data.Y,data.M,data.D)}},

  upY:function(){with(this){calendarChange(data.Y-1,data.M-1,data.D)}},

  upM:function(){with(this){calendarChange(data.Y,data.M-2,data.D)}},

  day:function(o){with(this){data.D=o;calendarChange(data.Y,data.M-1,data.D)}},

  data:{Y:null,M:null,D:null,W:null,H:null,U:null,YMD:null,YMD_C:"hot",ARR:null,TABLE:null,MN:null,WN:null,SELECT:null,TADAY:new Date(),TADAY_C:"taday",ROWLEN:7,VALUE:null},

  creatTable:function(){with(this){

  var table="<table height=100% width=100%><tr>"

  for(var i=0;i<data.ROWLEN;i++){var t=data.WN[i]||" ";table+="<th>"+t+"</th>";}

  for(var i in data.ARR){var showText=data.ARR[i]||" ",br=i%data.ROWLEN,title,css;

  if(!br){table+="</tr><tr>"};

  data.ARR[i]?title=data.Y+"-"+data.M+"-"+showText:title="";

  String(data.TADAY.getDate())==String(data.ARR[i])?

  (data.YMD.getFullYear()==data.TADAY.getFullYear()&&data.YMD.getMonth()==data.TADAY.getMonth()&&data.YMD.getDate()==data.TADAY.getDate())?

  css=data.TADAY_C+" "+data.YMD_C:css=data.YMD_C:css="";

  table+="<td title='"+title+"' class="+css+">"+showText+"</td>";

  }table+="</tr></table>"

  data.TABLE=table;return table;

  }},

  calendarStarArr:function(userY,userM,userD){with(this){

  var Arr=[];

  var now = new Date(userY,userM,userD);

  var LastDay = now.getLastDay();

  var FirstDayofWeek = now.FirstDayofWeek();

  data.YMD=now;data.Y=now.getFullYear();

  data.M=now.getMonth()+1;data.D=now.getDate();data.W=now.getDay();

  while(Arr.length!=FirstDayofWeek){Arr.push(false)}

  for(var i=0;i<LastDay;i++){Arr.push(i+1)}

  while(Arr.length%data.ROWLEN!=0){Arr.push(false)}

  data.ARR=Arr;return Arr;

  }},

  calendarChange:function(userY,userM,userD){with(this){

  calendarStarArr(userY,userM,userD);creatTable()

  }},

  calendarStar:function(userY,userM,userD){with(this){

  data.MN = ["零","一","二","三","四","五","六","七","八","九","十","十一","十二"];

  data.WN = ["日","一","二","三","四","五","六"];

  calendarChange(userY,userM,userD);

  }},

  init:function(){with(this){

  Date.prototype.getLastDay=function(){return(new Date(this.getFullYear(),this.getMonth()+1,0).getDate())}

  Date.prototype.FirstDayofWeek=function(){return(new Date(this.getFullYear(),this.getMonth(),1).getDay())}

  calendarStar(new Date().getFullYear(),new Date().getMonth(),new Date().getDate())

  }}

  }

  代码应用讲解:

  

复制代码 代码如下:

  var aa=new calendar()//创建一个新日历

  aa.init()//日历初始

  

复制代码 代码如下:

  obj.innerHTML=aa.STR()//显示日期字符串

  obj.innerHTML=aa.T()//显示表格

  aa.dnY()//下一年

  aa.upY()//上一年

  aa.dnM()//下一月

  aa.upM()//上一月

  aa.day(Number)//改变日历显示的几号(Number 需要传一个数值型参数)

  这个日历对象实现的是日历的核心功能功能,

  具体是日历放在哪里,

  哪个事件触发哪个函数这个我没有写,

  要是那样的话就失去我写这个日历的原有目的了。

  怎么大家都没反应,我弄个例子,大家看下吧
