How to check if the program is running with Administrator privileges in JavaScript

问题

Is there any way to check in JavaScript if the current program runs with administrative privileges?

For example in C# i can do it with the following code:

bool isRunningWithAdminApprovals;
WindowsIdentity identity = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(identity);
isRunningWithAdminApprovals = principal.IsInRole(WindowsBuiltInRole.Administrator);

However I need to check it with a current running script of javaScript. If i try to run an exe or a wrapper of the C# code, the UAC will prompt me to approve it and then i will already be in Administrative privilages...

Thanks

In modern browsers, the Javascript environment is run in a sandbox, so there's no way you can know anything about the system except those things that the browser put in the sandbox, ie the user agent string and a little more.

I fear you have to rely on other techniques, like Flash or Java, then retrieve the value with Javascript.
