1.比较日期大小
<script>
function CompareDate(d1,d2)
{
return ((new Date(d1.replace(/-/g,"\/"))) > (new Date(d2.replace(/-/g,"\/"))));
}
var current_time = "2007-02-02 7:30";
var stop_time = "2007-01-31 8:30";
alert(CompareDate(current_time,stop_time));
</script>
2.两个日期相差天数
<SCRIPT LANGUAGE="JavaScript">
<!--
/*
日期格式2008-01-20
*/
function DateDiff(sDate1,sDate2){
var aDate,oDate1,oDate2,iDays ;
aDate =sDate1.split('-');
oDate1 = new Date(aDate[1]+'-'+aDate[2]+'-'+aDate[0]) ;
//转换为04-19-2007格式
aDate = sDate2.split('-');
oDate2 = new Date(aDate[1]+'-'+ aDate[2] +'-'+aDate[0]);
iDays = parseInt(Math.abs(oDate1 -oDate2)/1000/60/60/24);//把相差的毫秒数转换为天数
return iDays ;
}
alert(DateDiff('2008-02-25','2008-03-02'));
//-->
</SCRIPT>
