<p>在下面的代码段中，我们创建了一个新的<code>AbortController</code>对象，并获取它的{{domxref("AbortSignal")}} (位于<code>signal</code>属性中)。然后我们用<code>aborted</code>属性检查这个信号是否已被放弃，并把相应的日志发送给终端。</p>
<pre class="brush: js">var controller = new AbortController();
var signal = controller.signal;
// ...
signal.aborted ? console.log('Request has been aborted') : console.log('Request not aborted');
