    ... 不用写了吧...
  }

Answer 2

function Compute(workTimeStart,workTimeEnd,refDate)
{
  var dayWorkMinute=(workTimeEnd-workTimeStart)*60;
  refDate=new Date(refDate.replace(/-/g,"/"));
  if(refDate.toString()=="NaN"){alert("错误的时间类型！");return -1;}
  var nowDate=new Date();
  if(refDate>nowDate){alert("请输入一个小于今天的时间！");return -1;}
  var totalMinute=0;  
  //计算天数差
  var days=parseInt((nowDate-refDate)/(1000*60*60*24));//求相隔的天数
  totalMinute+=days*dayWorkMinute;
  //计算日期时间的差
  var refHour=refDate.getHours(),refMinute=refDate.getMinutes(),nowHour=nowDate.getHours(),nowMinute=nowDate.getMinutes();
  if(refHour>=workTimeStart&&refHour<workTimeEnd)//计算传递的日期时间
   totalMinute+=(workTimeEnd-refHour)*60+refMinute;
  if(nowHour>workTimeStart&&nowHour<workTimeEnd)//计算现在的日期时间
   totalMinute+=(nowHour-9)*60+nowMinute;
  return totalMinute;
}//测试
var workMinute,refDate="2008-6-18 18:00:00";
workMinute=Compute(9,18,refDate);
if(workMinute!=-1)alert("从"+refDate+"到现在已经工作了"+workMinute+"分钟！");
refDate="2008-6-25 18:00:00";
workMinute=Compute(9,18,refDate);
if(workMinute!=-1)alert("从"+refDate+"到现在已经工作了"+workMinute+"分钟！");
refDate="2008-6-17 18:00:00";
workMinute=Compute(9,18,refDate);
if(workMinute!=-1)alert("从"+refDate+"到现在已经工作了"+workMinute+"分钟！");
refDate="2008-6-15 18:00:00";
workMinute=Compute(9,18,refDate);
if(workMinute!=-1)alert("从"+refDate+"到现在已经工作了"+workMinute+"分钟！");

Answer 3

(日期天数差-1)*9*60+(结束的点钟>18?18:结束的点钟<9?9:结束的点钟-开始的点钟>18?18:开始的点钟<9?9:开始的点钟)*60+(结束的分钟-开始的分钟)

Answer 4

呵呵你们的方法都不是很好,showbo大哥的运行后也有问题,然后我想出一个方法,改了改,先将时间格式化,如果在开始和结束时间以外就设置成开始时间和结束时间,然后工作时间=(格式化的现在时间-格式化后的开始时间)-(24-(工作时间))谢谢大家的帮助了,谢谢!!!

Answer 5

//是不是 计算时间差么？ 我给个简单的 
var ndata = "06/19/2008 20:12:02";
var pdate = "06/19/2008 20:12:20";
var sec = Date.parse(pdate) - Date.parse(ndata);
//sec 是毫秒 就看你想转换什么了
