JS计算两个日期相差几天

function Computation(sDate1, sDate2){
    var aDate, oDate1, oDate2, iDays    
    aDate = sDate1.split("-")    
    oDate1 = new Date(aDate[2] + ‘-‘ + aDate[1] + ‘-‘ + aDate[0])   
    aDate = sDate2.split("-")    
    oDate2 = new Date(aDate[2] + ‘-‘ + aDate[1] + ‘-‘ + aDate[0])    
    iDays = parseInt(Math.abs(oDate1 - oDate2) / 1000 / 60 / 60 /24)
    return iDays    
}
