parent.document.location.href="Login.aspx";//用户没有在线转到登录页面
}document.oncontextmenu=new Function("event.returnValue=false;");
var fileLocation=parent.document.location.href.toLowerCase();
改为：
var fileLocation=parent.location.toLowerCase();parent.document.location.href="Login.aspx";
改为：
parent.location.replace("Login.aspx");
为什么每次登录都找不到在线的用户？？
改为：
var fileLocation=parent.location.toLowerCase();parent.document.location.href="Login.aspx";
改为：
parent.location.replace("Login.aspx");改完还是没用啊
