html - How to get the name of the current Windows user in JavaScript

Question

I was wondering how I would get the name of the current user in JavaScript as part of an HTML document.

In Java, one would type System.getProperty("user.name"); to achieve this. What is the alternative to this in JavaScript?

Answer 1

JavaScript runs in the context of the current HTML document, so it won't be able to determine anything about a current user unless it's in the current page or you do AJAX calls to a server-side script to get more information.

JavaScript will not be able to determine your Windows user name.
