javascript自定义日期比较函数用法示例

<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";
console.log(CompareDate(current_time,stop_time));
</script>

<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 ;
}
console.log(DateDiff('2008-02-25','2008-03-02'));
