先看看效果:
使用很简单;
先创建一个Calendar对象
var calendar=new Calendar();
只要调用show()方法即可显示
calendar.show()
其实调用的是pj库的show方法
因此在使用之前要先把pj库引进来,在把Calendar.js引进来就可以
Calendar的主要方法有
getDateString([pattern]) format是日期格式,默认是yyyy-mm-dd
show:function(duration) 显示日历
hide:function(duration)隐藏日历
fadeIn:function(duration)淡入日历
fadeOut:function(duration)淡出日历
locateAt:function(obj,offsetX,offsetY)把日历定位到指定的元素正下方,offsetX、offsetY可选,是相对于X、Y轴的偏移量
只定义了两个事件
onChange(fn)//当改变年份或者月份是的事件监听器,以当前Calendar对象为上下文执行fn函数
onSelect(fn)//当选择日期时触发的函数,以当前Calendar对象为上下文执行fn函数
还是把源代码粘贴上来吧(有点多,因为封装了一个table)
//date:默认开始日期,不需要可以是null(以当天日期开始),yearListLength:年份下拉列表长度
function Calendar(date,yearListLength){
var currentDate=date||new Date(),_this=this;
this.container=pj("
this.container.get().innerHTML='

this.selects=pj("select",this.container.get());
this.getCurrentDate=function(){return currentDate;};
this.init();
this.initYearList(yearListLength||70);
var change=function(){},select=function(){};
this.onChange=function(fn){//当改变年份或者月份是的事件监听器,以当前Calendar对象为上下文执行fn函数
