这么我要根据时间差来判断，我点击调试过，点击按钮的id都是对的，但是里面的开始时间和结束时间总是第一条数据的开始时间和结束时间，求大神指导，已经试过很多方法，怎么弄都不行！！！！
function arrove(idpermision) { //根据假单的时间间隔来判断，如果是小于三天就是经理审批，大于三天小于七天就是经理和副总审批，大于七天就是一级一级的审批上来最后由hr审批
//
//判断请假时间
alert(idpermision);
var star = document.getElementById("permsstart").value;//获取页面的开始时间
var end = document.getElementById("permsend").value;//获取页面的结束时间
var time1 = new Date(Date.parse(star)).getTime();
var time2 = new Date(Date.parse(end)).getTime();
alert(time1);
alert(time2);
var day = (time2 -time1)/(24*3600*1000); //判断结束时间和开始时间的间隔天数
var s="<%=session.getAttribute("pos")%>"; //根据角色添加间隔时间的判断用户是否可以点击
var posname = document.getElementById("PosName").value;
alert(day);
///判断当前申请者为职员，根据时间来判断
if(posname.indexOf("职员") >= 0 ){
if( s == "经理" ){ //在小于三天当前w可以修改其他都不可以修改
document.myform.action = "permapprconf.jsp?idpermision="+idpermision;
document.myform.submit();
return true;
}else {
if( day >3 && s == "副总" && posname.indexOf("职员") >= 0 ){
s.disabled = false;
document.myform.action = "permapprconf.jsp?idpermision="+idpermision;
document.myform.submit();
}
if( day > 7 && s == "HR" && posname.indexOf("职员") >= 0 ){
s.disabled = false;
document.myform.action = "permapprconf.jsp?idpermision="+idpermision;
document.myform.submit();
