<p><strong><code>WindowEventHandlers</code></strong> describes the event handlers common to several interfaces like {{domxref("Window")}}, or {{domxref("HTMLBodyElement")}} and  {{domxref("HTMLFrameSetElement")}}. Each of these interfaces can implement more event handlers.</p>

<p><em>The events properties, of the form <code>onXYZ</code>, are defined on the {{domxref("WindowEventHandlers")}}, and implemented by {{domxref("Window")}}, and {{domxref("WorkerGlobalScope")}} for Web Workers.</em></p>
