利用JS实现简单的日期选择插件

首先是调用方法如下

//调用方法，后面回调函数返回的是当前选择的日期 
calender('#calend').init(function(date){ 
 this.innerHTML = date 
});

//具体参数说明 
//如果需要传入参数，第一个为json，第二个为回调函数 
//下面是format格式化显示格式类型，有如下几种： 
//yyyy为年数  
//大写M为月数  
//d为几号  
//h为小时  
//小写m为分钟  
//s为秒数  
//q为季度  
//小写e，为数字星期格式  
//大写E，为中文星期格式  
//举例：'yyyy年MM月dd日','yyyy-MM-dd','yyyy','MM','e','dd E' 
//注意：以上获取时间如果是个位数则返回个位数，比如7月，则返回7，如果需要返回07，参数可以写成这样“MM”，其它同理，由于时分秒功能还没有添加，默认获取当前时分秒  
calender('#calend').init({ 
 date : [2015,12,12], //设置默认显示年月日，默认当前年月日  
 format : 'yyyy-MM-dd', //设置显示格式 
 button : false //是否显示按钮 
 left : 0, //追加left，默认0
 top :0, //追加top，默认0
 onload : function(){ } //初始化完成执行，this为当前创建的日历对象 
},function(date){ 
 //回调函数 
 this.innerHTML = date 
});
