JS 两日期相减，获得天数

function DateDiff(sDate1,sDate2)
{ 
    var arrDate,objDate1,objDate2,intDays;
    arrDate=sDate1.split("-");
    objDate1=new Date(arrDate[1]+'-'+arrDate[2]+'-'+arrDate[0]);
    arrDate=sDate2.split("-");
    objDate2=new Date(arrDate[1] + '-'+arrDate[2]+'-'+arrDate[0]);
    intDays=parseInt(Math.abs(objDate1-objDate2)/1000/60/60/24);
    return intDays;
}
