<p>在 <a href="https://mdn.github.io/emogotchi/">Emogotchi demo</a> (<a href="https://github.com/mdn/emogotchi">see source code</a>)中, 我们在激活一个桌面通知时,调用了<code>spawnNotification()</code>函数—函数被传入了指定的参数 body、icon、title , 创建了一个必选对象传入{{domxref("Notification.Notification","Notification()")}} 构造函数创建了一个实例.</p>

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