我创建了Chrome扩展程序并使用pusher从服务器接收一些数据。 当我测试它显示多个重复数据，因为它遵循我打开的选项卡。 任何人都了解我。请帮助我。提前谢谢你。
Content.js
Pusher.Util.getLocalStorage = function()
{
return undefined;
}
Pusher.ScriptRequest.prototype.send = function(receiver) {
var xhr = new XMLHttpRequest();
xhr.open("GET", this.src, true);
xhr.send();
}
document.addEventListener('DOMContentLoaded', function () {
if (Notification.permission !== "granted")
Notification.requestPermission();
});
var pusher = new Pusher('xxxxxxxxxxxxxxxxxxxxx');
var notificationsChannel = pusher.subscribe('notifications');
notificationsChannel.bind('new_notification', function(notification){
// assign the notification's message to a <div></div>
var message = notification.message;
if (!Notification) {
alert('Desktop notifications not available in your browser. Try Chromium.');
return;
}
if (Notification.permission !== "granted")
Notification.requestPermission();
else {
console.log(message);
var notification = new Notification('แจ้งเตือน', {
icon: 'img/LOGO.png',
body: message,
});
notification.onclick = function () {
location.reload();
};
}
});
