Notification的只读属性icon使得包含icon的 URL 被显示成通知的一部分，如同指定Notification()构造函数中icon的属性。
Note: 此特性在 Web Worker 中可用。
语法
var icon = Notification.icon;
值
一个 USVString。
示例
在此示例中，当我们想要发出一个通知时，我们运行一个简单的 spawnNotification() 函数——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options对象，并使用Notification()构造函数来触发通知。
function spawnNotification(theBody,theIcon,theTitle) {
var options = {
body: theBody,
icon: theIcon
}
var n = new Notification(theTitle,options);
}
