<div>{{ApiRef("HTML DOM")}}</div>
<p>{{domxref("WindowOrWorkerGlobalScope")}} mixin 的 <strong><code>clearInterval()</code></strong> 方法可取消先前通过 {{domxref("WindowOrWorkerGlobalScope.setInterval", "setInterval()")}} 设置的重复定时任务。</p>
<h2 id="语法">语法</h2>
<pre class="syntaxbox"><em>scope</em>.clearInterval(<var>intervalID</var>)
</pre>
<h3 id="Parameters">Parameters</h3>
<dl>
<dt><code>intervalID</code></dt>
<dd>要取消的定时器的 ID。是由 <code>setInterval()</code> 返回的。</dd>
</dl>
<p>值得一提的是，{{domxref("WindowOrWorkerGlobalScope.setInterval", "setInterval()")}} 和 {{domxref("WindowOrWorkerGlobalScope.setTimeout", "setTimeout()")}} 共用其定义的 IDs，即可以使用 <code>clearInterval()</code> 和 {{domxref("WindowOrWorkerGlobalScope.clearTimeout", "clearTimeout()")}} 中的任意一个。然而，为了使代码可读性更强，你应该尽量避免这种用法。</p>
<h3 id="返回值">返回值</h3>
