Retrieving Hardware Information using Advanced JavaScript with Internet Explorer - How to retrieve a computer's motherboard information using JavaScript
(Page 3 of 5 )
Now, let us try to develop a simple script (JavaScript) which shows the technique for displaying the information related to the motherboard belonging to a computer. The entire code for the sample is as follows:
<!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_BaseBoard");
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.HostingBoard + "</td>");
document.write("<td>" + p.Manufacturer + "</td>");
document.write("<td>" + p.PoweredOn + "</td>");
document.write("<td>" + p.Product + "</td>");
document.write("<td>" + p.SerialNumber + "</td>");
document.write("<td>" + p.Version + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
function dispHeading()
{
document.write("<thead>");
document.write("<td>HostingBoard</td>");
document.write("<td>Manufacturer</td>");
document.write("<td>PoweredOn</td>");
document.write("<td>Product</td>");
document.write("<td>SerialNumber</td>");
document.write("<td>Version</td>");
document.write("</thead>");
}
//-->
</script>
</head>
<body>
<INPUT id="Button1" type="button" value="Button"
name="Button1" language="javascript" onclick="return Button1_onclick()">
</body>
</html>
The above sample would automatically list all motherboards belonging to a computer. It mainly lists the manufacturer, product information, serial number of the motherboard and its version. To retrieve this information, I used a built-in class, “Win32_BaseBoard.”
The “for” loop I used in the above code iterates for every motherboard present in the system and finally retrieves only the properties of that motherboard.
