js比较日期大小的方法

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。
