<p>Welcome to the push messaging codelab. The button below needs to be
fixed to support subscribing to push.</p>

<p>Once you've subscribed your user, you'd send their subscription to your
server to store in a database so that when you want to send a message
you can lookup the subscription and send a message to it.</p>
<p>To simplify things for this code lab copy the following details
into the <a href="https://web-push-codelab.glitch.me//">Push Companion
Site</a> and it'll send a push message for you, using the application
server keys on the site - so make sure they match.</p>

目前，我可以通过访问我的开发者模式>应用程序>服务人员来推送通知。但是我想通过我创建的按钮来获得它。我想我已经得到了答案，showNotification是我所需要的全部，对于有相同问题的任何人，请尝试这个。为我工作
self.addEventListener('push', function (event) {
if (!(self.Notification && self.Notification.permission === 'granted')) {
return;
}
var data = {};
if (event.data) {
data = event.data.json();
}
console.log('Notification Received:');
console.log(data);
try {
var title = data.title;
var message = data.message;
var url = data.data.url;
var icon = "images/ns-logo.png";
event.waitUntil(self.registration.showNotification(title, {
body: message,
icon: icon,
badge: icon,
data: url
}));
}
catch (err) {
console.log('Notification Processing Failed:', err);
}
});
通常，这个实现应该转到ServiceWorker js文件，这样任何推送到达都会显示给用户，而无需最终用户手动干预- 自我注册。showNotification（…）
确保您已经注册了sw.js，并允许权限通知浏览器 HTML
var btnnotify = document.querySelector('#ABCD');
btnnotify.addEventListener('click', function () {
navigator.serviceWorker.getRegistration().then(sw => {
let options = {
body: "Let's buy some Nendoroid!",
icon: "img/Sukusuku Hakutaku.png",
};
sw.showNotification("I want to buy a Nendoroid!", options);
});
});
notifyButton.addEventListener('click', function() {
const title = 'Simple Title';
const options = {
body: 'Simple piece of body text.\nSecond line of body text :)'
};
swRegistration.showNotification(title, options);
})
self.addEventListener('push', function (event) {
if (!(self.Notification && self.Notification.permission === 'granted')) {
return;
}
var data = {};
if (event.data) {
data = event.data.json();
}
console.log('Notification Received:');
console.log(data);
try {
var title = data.title;
var message = data.message;
var url = data.data.url;
var icon = "images/ns-logo.png";
event.waitUntil(self.registration.showNotification(title, {
body: message,
icon: icon,
badge: icon,
data: url
}));
}
catch (err) {
console.log('Notification Processing Failed:', err);
}
});
<button id="ABCD" class="btn btn-block">Notify</button>
var btnnotify = document.querySelector('#ABCD');
btnnotify.addEventListener('click', function () {
