js比较日期大小的方法

function DateDiff(d1,d2){ var result = Date.parse(d1.replace(/-/g,"https://www.jb51.net/"))- Date.parse(d2.replace(/-/g,"https://www.jb51.net/")); 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; }
