如何访问身后会话对象的成员变量一个asp.net code在JavaScript？ [英] How do you access an asp.net code behind session object member variable in javascript?

问题描述

我有一个处理我所有的会话变量在我的asp.net应用程序的类。此外，我有时在会话变量存储对象，从而让我code非常相似，一个正常的.NET应用程序。

I have a class that handles all of my session variables in my asp.net application. Moreover, I sometimes store objects in the session variables so as to allow me to code very similar to a normal .net application.

例如，这里是一个对象在会话变量：

For example, here is an object in a session variable:

public cUser User
{
    get { return (cUser)HttpContext.Current.Session["CurrentUser"]; }
    set { HttpContext.Current.Session["CurrentUser"] = value; }
}

这是MySessionClass的实例：

And here is the instance of MySessionClass:

    public static MySessinClass Current
    {
        get
        {
            MySessionClass session = (MySessionClass)HttpContext.Current.Session["MySessionClass"];
            if (session == null) {
                session = new MySessionClass();
                HttpContext.Current.Session["MySessionClass"] = session;
            }
            return session;
        }
    }

所以，在后面的aspx页面我的code，我只想做一些诸如

So, in my code behind aspx page, I would just do something such as

int userID = MySessionClass.Current.User.UserID;

这个伟大的工程，我喜欢它。不过，我想从我的aspx页面在JavaScript中采用同样的原则：

This works great and I love it. However, I want to apply the same principle in javascript from my aspx page:

var userID = <%=MySessionClass.Current.User.UserID%>;

然而，当我访问该网页，我得到一个错误说，它不承认MySessionClass对象。

However, when I access that webpage, I get an error saying that it does not recognize the MySessionClass object.

所以，考虑到我的背景下，这将是引用一个用户名变量，从对象，从会话，在JavaScript中的最佳方式？也许我的语法来引用它关闭或我在它走错了路。任何帮助将是AP preciated，谢谢你。

So, given the context that I am in, what would be the best way to reference that UserID variable, from the object, from the session, in javascript? Maybe my syntax to reference it is off or I am going at it the wrong way. Any help would be appreciated, thank you.

推荐答案

既然你已经将它定义为一个静态成员，您将需要的页面类型限定您参考：

Since you've defined it as a static member, you would need to qualify your reference with the page type:

var userID = <%=MyPageType.MySessionClass.Current.User.UserID%>; 

这应该够了。
