Advanced JavaScript with Internet Explorer: Retrieving Networking Configuration Information
This is the second article in a series focusing on retrieving system (or client) information using JavaScript and presenting the same on a web page.

Advanced JavaScript with Internet Explorer: Retrieving Networking Configuration Information - How to retrieve network client information using JavaScript (Page 3 of 6 )
The following JavaScript code should support you with some minimum information about the network clients available on your system.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title></title> <meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1"> <meta name="vs_targetSchema" content="http://schemas. microsoft.com/intellisense/ie5"> <script id="clientEventHandlersJS" language="javascript"> <!--
function Button1_onclick() { var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_NetworkClient"); var e = new Enumerator (properties); document.write("<table border=1>"); dispHeading(); for (;!e.atEnd();e.moveNext ()) { var p = e.item (); document.write("<tr>"); document.write("<td>" + p.Caption + "</td>"); document.write("<td>" + p.Description + "</td>"); document.write("<td>" + p.InstallDate + "</td>"); document.write("<td>" + p.Manufacturer + "</td>"); document.write("<td>" + p.Name + "</td>"); document.write("</tr>"); } document.write("</table>"); }
The above would automatically list all network clients installed on your computer. The details include caption, description, Install date, manufacturer and name. To retrieve this information, I used a built-in class, “Win32_NetworkClient.”
The “for” loop I used in the above code iterates for every network client present in the system and finally retrieves only the properties of that network client.
