<h2 id="示例">示例</h2>

<p>在此<a href="https://github.com/mdn/emogotchi">示例</a>中，当我们想要发出一个通知时，我们运行一个简单的 <code>spawnNotification() 函数</code>——这是传递参数来指定我们想要的主体、图标和标题，然后它创建必要的<code>options</code>对象，并使用{{domxref("Notification.Notification","Notification()")}}构造函数来触发通知。</p>

<pre class="brush: js">function spawnNotification(theBody,theIcon,theTitle) {
  var options = {
      body: theBody,
      icon: theIcon
  }
  var n = new Notification(theTitle,options);
}</pre>
