SelectDay: new Date().setDate(10), onSelectDay: function(o){ o.className = "onSelect"; },
而onToday就用来设置今日日期的样式,
例如实例里面把今天的日期的样式设为onToday:
onToday: function(o){ o.className = "onToday"; },
在onFinish中可以放需要设置日历的程序。
可以通过this.Year和this.Month获取当前日历显示的年份和月份。
对有数据的日期的也在这里设置,例如实例中是有一个当前月份的有数据的日期列表,然后根据这个列表对相应的日期进行设置:
var flag = [10,15,20]; for(var i = 0, len = flag.length; i < len; i++){ this.Days[flag[i]].innerHTML = "<a href='javascript:void(0);' onclick=\"alert('日期是:"+this.Year+"/"+this.Month+"/"+flag[i]+"');return false;\">" + flag[i] + "</a>"; }
实例中是固定了这个日期列表,实际应用中可以根据年份月份获取对应的日期列表,
个人推荐用年份月份通过ajax获取。
程序中还有两个有用的方法PreMonth(显示上一个月)和NextMonth(显示下一个月)。
