Module: Dommy::WindowReflectingHandlers

Included in:
HTMLBodyElement, HTMLFrameSetElement
Defined in:
lib/dommy/html_elements.rb

Overview

The "Window-reflecting body element event handler set": setting one of these event handler IDL attributes on / (body.onload = fn) actually targets the WINDOW, per HTML — so window.onload fires. A non-reflected handler (body.onclick) stays on the element.
