altHtml property (applet, object)

Browser support:
Sets or retrieves the HTML content that is executed if the object or applet element fails to load.
A value for the altHtml property can be specified in an event handler for the onerror event. For a cross-browser solution, write the HTML content in the object and applet elements. It has the same effect. See the examples for details.

Syntax:

object.altHtml;
