Silverlight JavaScript Reference

Using the Silverlight Plug-in

There are two ways to access the Silverlight plug-in. Use the HTML DOM and the document.getElementById() method, and provide the ID used in the createSilverlight() function. Or intercept any Silverlight event and access the plug-in in the following fashion:

function eventHandler(sender, eventArgs) {
  var plugin = sender.getHost();
}
