Remarks

Setting event handlers declaratively (in HTML)

To set the event handler declaratively, it must be accessible to the global scope, and you must also call WinJS.Utilities.markSupportedForProcessing or WinJS.UI.eventHandler on the handler. You can make the handler accessible to the global scope by using WinJS.Namespace.define. For more info, see How to set event handlers declaratively.

Requirements

Minimum WinJS version	WinJS 3.0
Namespace	WinJS.UI
