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

<script type="text/javascript" src="api.js" />
<body onload="testapi()">
<embed type="application/x-systeminfo-widget" hidden="yes"></embed>


  • 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);
