Retrieving More Hardware Information With Internet Explorer and JavaScript
(Page 1 of 7 )
This is the fourth and last article in this series, which focuses on retrieving hardware information using JavaScript and presenting it on a web page. You can directly copy and paste the code samples present in this article into a file with the extension “.htm” and open them in Internet Explorer 5.5+.
As I am using the “Web Based Enterprise Management” (WBEM) strategy of Microsoft, the samples would work only with IE 5.5+
How to list the BIOS information available in a computer using JavaScript
Now, let us try to develop a simple script (JavaScript) which shows the technique for retrieving BIOS information available in 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">
<!--
functionButton1_onclick() {
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_BIOS");
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.BIOSVersion(0) + "</td>");
document.write("<td>" + p.CurrentLanguage + "</td>");
document.write("<td>" + p.Description + "</td>");
document.write("<td>" + p.Manufacturer + "</td>");
document.write("<td>" + p.PrimaryBIOS + "</td>");
document.write("<td>" + p.ReleaseDate + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
functiondispHeading()
{
document.write("<thead>");
document.write("<td>Version</td>");
document.write("<td>Language</td>");
document.write("<td>Description</td>");
document.write("<td>Manufacturer</td>");
document.write("<td>PrimaryBIOS</td>");
document.write("<td>ReleaseDate</td>");
document.write("</thead>");
}
//-->
</script>
</head>
<body> <INPUT id="Button1" type="button" value="Button" name="Button1"
language="javascript" onclick="return Button1_onclick()">
</body>
