我有一个服务工作者,创建了一个 Websocket 来监听通知,它可以正常工作。但是当我尝试显示通知时,却无法实现。以下是代码:
function displayNotification(title, body, tag, url, actions) {
if (Notification.permission == "granted") {
if (title == undefined || title == null || title == "") title = "My site"
if (body == undefined || body == null) body = ""
if (tag == undefined || tag == "") tag = null
if (url == undefined || url == null || url == "") url = "https://example.com/"
if (actions == undefined || actions == null || actions == "") actions = []
actions.push({ action: "close", title: "Close" })
self.ServiceWorkerRegistration.showNotification(//self.ServiceWorkerRegistration.showNotification is not a function
title,
body,
lang: "en-US",
icon: "https://example.com/images/logo.png",
badge: "https://example.com/images/logo.png",
vibrate: [100, 50, 100],
data: {
dateOfArrival: Date.now(),
url
},
timestamp: Date.now(),
actions,
tag
})
}
}
我还尝试了 self.showNotification()
和 this.showNotification()
,但两者都是 null
