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
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:
var aa=new calendar()//创建一个新日历 aa.init()//日历初始
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
