<p><strong><code>WindowEventHandlers.onstorage</code></strong> 属性包含一个在{{event("storage")}}事件触发时的事件句柄。 </p>
<p>注意：该事件不在导致数据变化的当前页面触发（如果浏览器同时打开一个域名下面的多个页面，当其中的一个页面改变 <code>sessionStorage</code> 或 <code>localStorage</code> 的数据时，其他所有页面的 <code>storage</code> 事件会被触发，而原始页面并不触发 <code>storage</code> 事件）</p>
