I tried to get the windows user name in IE browser only using the below code.

function GetUserName() 
{ 
    var wshell = new ActiveXObject("WScript.Shell"); 
    alert(wshell.ExpandEnvironmentStrings("%USERNAME%")); 
} 

How to get the windows username in other browsers like chrome, mozilla, safari.

• javascript
• jquery
• angularjs

• 6 Uhm. I'm surprised you can do this in IE! This is incredibly intrusive and shouldn't be done. I'm pretty sure that privacy conscious browsers like Chrome and Safari dont do that. They also dont support ActiveX. Thank god. – somethinghere Commented Mar 24, 2015 at 12:06

I Agree with Eric ment. However try following hacks. Most likely to work in win7

In IE

var objUserInfo = new ActiveXObject("WScriptwork");
document.write(objUserInfo.ComputerName+"<br>"); 
document.write(objUserInfo.UserDomain+"<br>"); 
document.write(objUserInfo.UserName+"<br>");  
var uname =  objUserInfo.UserName;
alert(uname);

Firefox:

function getUser() {
   return Components
     .classes["@mozilla/process/environment;1"]
     .getService(Components.interfaces.nsIEnvironment)
     .get('USERNAME');
}

As of today it is impossible, and will most likely be in the future as well.

The only quirk I can e up with; is to run a custom Java-Applet that checks it for you. However this is a passive action, and thus, you can not automatically extract it without the clients permission.
