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：

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 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。
