本文实例讲述了js比较日期大小的方法。分享给大家供大家参考。具体如下：
function datediff(d1,d2){ var result = date.parse(d1.replace(/-/g,/))- date.parse(d2.replace(/-/g,/)); return result;}function datediff(d1,d2){ start_at = new date(d1.replace(/^(\d{4})(\d{2})(\d{2})$/,$1/$2/$3)); end_at = new date(d2.replace(/^(\d{4})(\d{2})(\d{2})$/,$1/$2/$3)); if(start_at > end_at) { return false; } return true;}//js获取当前日期function currentday(){ var mydate=new date(); var mymonth=mydate.getmonth()+1; var myday= mydate.getdate(); var myyear= mydate.getyear(); mymonth=mymonth<10?0+mymonth:mymonth; myday=myday<10?0+myday:myday; var day=myyear+-+mymonth+-+myday; return day;}
希望本文所述对大家的javascript程序设计有所帮助。
