Defining HTML

To enable system info API in widgets it needs to be embedded in the document since it is implemented as a netscape scriptable plug-in.

  <embed type="application/x-systeminfo-widget" hidden="yes"></embed>

HTML example

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" 
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script type="text/javascript" src="api.js" />
<body onload="testapi()">
<embed type="application/x-systeminfo-widget" hidden="yes"></embed>
</body>
</html>

JavaScript

  • Lets use the [void] sysinfo.beep(Int frequency, Int duration) api as an example : It produces a beep tone in a specified frequency for a specified duration.
function testapi() 
// First lets get the reference to the sysinfo object.
var sysinfo = document.embeds[0];
//
sysinfo.beep(5000, 900);
};
