时间相加减（小森请假流程）

JS（请假等）：

function enfocus()
{
var t1 = document.forms[0].DATA_65.value;
var t2 = document.forms[0].DATA_66.value;
var t3 = document.forms[0].DATA_67.value;

var date2 =newDate(t2);
if(date1.toLocaleDateString()== date2.toLocaleDateString()){

elseif(date1.getHours()<=12&& date2.getHours()>=13)
{document.getElementById("DATA_67").value = date2.getHours()-date1.getHours()-1;}
else
{document.getElementById("DATA_67").value = date2.getHours()-date1.getHours();}
}

date1.setHours(date1.getHours()+1);
}
if(date2.getHours()>=13){
date2.setHours(date2.getHours()-1);
}
var a = date1.toLocaleDateString();
//将时间转换成年月日（去掉小时数）
var a1 =newDate(a);
//将时间转换成标准格式
var time1 = a1.getTime();
//将时间装换成毫秒
var b = date2.toLocaleDateString();

var hours;
hours = firstday + lastday + day*8;

}

JS（加班）：

function enfocus()

{document.getElementById("DATA_67").value = date2.getHours()-date1.getHours()-1;}
elseif(date1.getHours()< date2.getHours()&& date1.getHours()>18)
{document.getElementById("DATA_67").value = date2.getHours()-date1.getHours();}
else
{document.getElementById("DATA_67").value ="error";}
}
elseif(date1.toLocaleDateString()< date2.toLocaleDateString()&&
date1.getHours()>=18&& date2.getHours()<=9){
if(date1.getHours()==18){
date1.setHours(date1.getHours()+1);}
var firstday;
firstday = date1.getHours();
var lastday;
lastday = date2.getHours();
var hours;
hours =24- firstday + lastday;

}
else{document.getElementById("DATA_67").value ="error";}
}
