<p><a href="/zh-CN/docs/Web/API/Window/en/Gecko">Gecko</a>({{ Bug(112288) }})中未实现<code>window.ondragdrop</code>属性和<code>ondragdrop</code>属性,您必须使用<code>addEventListener</code>。 有关详细信息,请参见<a href="/zh-CN/docs/Web/API/Window/en/DOM/element.addEventListener">addEventListener</a>。</p>

<p>在此示例中,事件侦听器被添加到窗口(事件目标)。 如果从外部源将选项卡,链接,标记的文本或文件拖放到此窗口上,则会触发警报。 注意<code>event.stopPropagation()</code>; 阻止浏览器加载放置的标签,链接或文件。</p>
