方法一：

/+--------------------------------------------------- //| 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); }

方法二：

function  btnCount_Click(){         s1  =  "2006-12-18"         s2  =  "2007-1-5"         alert("第一个日期；"+s1+"/n第二个日期："+s2+"/n相差"+DateDiff(s1,s2)+"天")     }     //计算天数差的函数，通用     function  DateDiff(sDate1,  sDate2){    //sDate1和sDate2是2006-12-18格式         var  aDate,  oDate1,  oDate2,  iDays         aDate  =  sDate1.split("-")         oDate1  =  new  Date(aDate[1]  +  '-'  +  aDate[2]  +  '-'  +  aDate[0])    //转换为12-18-2006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     }
