HTML Standard defines WindowEventHandlers
interface mixin WindowEventHandlers {
attribute EventHandler onafterprint;
attribute EventHandler onbeforeprint;
attribute OnBeforeUnloadEventHandler onbeforeunload;
attribute EventHandler onhashchange;
attribute EventHandler onlanguagechange;
attribute EventHandler onmessage;
attribute EventHandler onmessageerror;
attribute EventHandler onoffline;
attribute EventHandler ononline;
attribute EventHandler onpagehide;
attribute EventHandler onpagereveal;
attribute EventHandler onpageshow;
attribute EventHandler onpageswap;
attribute EventHandler onpopstate;
attribute EventHandler onrejectionhandled;
attribute EventHandler onstorage;
attribute EventHandler onunhandledrejection;
attribute EventHandler onunload;
};This interface mixin is extended in the following specifications:
- Portals
partial interface mixin WindowEventHandlers { attribute EventHandler onportalactivate; }; - Gamepad
partial interface mixin WindowEventHandlers { attribute EventHandler ongamepadconnected; attribute EventHandler ongamepaddisconnected; };
Consolidated IDL (across partials)
interface mixin WindowEventHandlers {
