Answer 1

//+---------------------------------------------------   
//| 求两个时间的天数差 日期格式为 YYYY-MM-dd    
//+---------------------------------------------------   
function daysBetween(DateOne,DateTwo)   
{    
    var OneMonth = DateOne.substring(5,DateOne.lastIndexOf ('-'));   
    var OneDay = DateOne.substring(DateOne.length,DateOne.lastIndexOf ('-')+1);   
    var OneYear = DateOne.substring(0,DateOne.indexOf ('-'));   
   
    var TwoMonth = DateTwo.substring(5,DateTwo.lastIndexOf ('-'));   
    var TwoDay = DateTwo.substring(DateTwo.length,DateTwo.lastIndexOf ('-')+1);   
    var TwoYear = DateTwo.substring(0,DateTwo.indexOf ('-'));   
   
    var cha=((Date.parse(OneMonth+'/'+OneDay+'/'+OneYear)- Date.parse(TwoMonth+'/'+TwoDay+'/'+TwoYear))/86400000);    
    return Math.abs(cha);   
}

<script   language="JavaScript">   
  <!--   
  var   oldtime=new   Date("2005","1","10","8","0","00");   
  var   newtime=new   Date("2005","1","11","12","0","00");   
    
  var   diff   =   (newtime.valueOf()   -   oldtime.valueOf())/(1000*3600)   ;   
  var   hours=parseInt(diff,10);   
  alert(hours);   
  //-->
