<h2 id="Summary" name="Summary">摘要</h2>
<p>一个中断事件的事件处理器发送到window全局对象。（Firefox 2 和Safari不可用）</p>
<p>TODO 要定义什么是“abort”。通过窗口管理关掉窗口么？停止页面的加载？有什么意图和理由（用户，网络或服务器）？在哪一步被发起或被捕获？对于IE浏览器，onabort只可用于<code>img</code>标签。</p>
<h2 id="Syntax" name="Syntax">语法</h2>
<pre class="syntaxbox">window.onabort =<em>funcRef</em>
</pre>
<ul>
<li><code>funcRef</code>是一个函数引用</li>
