The client loads applications, embedded objects, and images as soon as it encounters the applet, embed, and img objects during parsing. Consequently, the HTMLFrameSiteEvents::onload event for these objects occurs before the client parses any subsequent objects. To ensure that an event handler receives the HTMLFrameSiteEvents::onload event for these objects, place the script object that defines the event handler before the object and use the HTMLFrameSiteEvents::onload attribute in the object to set the handler.

The HTMLFrameSiteEvents::onload attribute of the body object sets an HTMLFrameSiteEvents::onload event handler for the window. This technique of calling the window HTMLFrameSiteEvents::onload event through the body object is overridden by any other means of invoking the window HTMLFrameSiteEvents::onload event, provided the handlers are in the same script language.

Loads the object for which the event is specified.

To invoke this event, do one of the following:

  • Open a document to invoke this event for the document or any object within it.

The pEvtObj parameter is required for the following interfaces:
