同時發送一個Chrome擴展程序桌面通知

Question

我仍在學習如何創建Chrome擴展程序，但我的問題是使用桌面通知。我能夠觸發通知，但是當發生這種情況時，我會觸發內容腳本1的桌面通知。桌面通知也會觸發內容腳本2.我如何使它不會同時觸發，以及只有當他們被稱爲？

背景頁面

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { 
    // Create a simple text notification 
    var notifyWinner = webkitNotifications.createNotification('48.png', 'Notification', request.winnerMessage); 
    notifyWinner.show(); 
    setTimeout(function(){ notifyWinner.cancel(); },10000); 
}); 

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { 
    // Create a simple text notification 
    var notifyVideo = webkitNotifications.createNotification('48.png', 'Notification', request.videoMessage); 
    notifyVideo.show(); 
    setTimeout(function(){ notifyVideo.cancel(); },10000); 
}); 

內容腳本1

chrome.extension.sendRequest({winnerMessage: "You won!!!"}, function(response) { 
       return response; 
      }); 

內容腳本2

chrome.extension.sendRequest({videoMessage: "There is a video" + videoURL}, function(response) { 
         return response; 
        }); 

Answer 1

你Ç將代碼簡化爲僅使用一個onRequest監聽器，然後它將停止顯示重複通知。

BACKGROUND_PAGE

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { 
    // Create a simple text notification 
    var notify = webkitNotifications.createNotification('48.png', 'Notification', request.message); 
    notify.show(); 
    setTimeout(function(){ notify.cancel(); },10000); 
}); 

content_script

chrome.extension.sendRequest({ 
    message: "There is a video" + videoURL}, // Change the message here as needed. 
    function(response) { 
    return response; 
});
