Chrome扩展桌面通知在休眠时有效

本文介绍了Chrome扩展桌面通知在休眠时有效的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我做了一个桌面通知，每隔1分钟就会显示一个通知。 10秒后，自行关闭。

我去吃午饭，然后电脑进入睡眠状态。当我回来时，我唤醒了我的电脑，然后很多通知开始了。

我该如何处理这个问题？我想如果电脑睡觉它不应该显示通知。我如何控制它？

Background.js

function show（）{ var notification = webkitNotifications.createHTMLNotification（'notification.html'）; notification.show（）; } //有条件地初始化选项。 if（！localStorage.isInitialized）{ localStorage.isActivated = true; //显示激活。 localStorage.frequency = 1; //显示频率，以分钟为单位。 localStorage.isInitialized = true; //选项初始化。 } if（window.webkitNotifications）{ //激活时，以显示频率显示通知。 if（JSON.parse（localStorage.isActivated））{show（）; } var interval = 0; //显示时间间隔，以分钟为单位。 setInterval（function（）{ interval ++; chrome.idle.queryState（15，state）; if（localStorage.frequency< =间隔&&状态==活动） {show（）; interval = 0; } }，60000）; $ b $ / code>

解决方案

code> Chrome.idle API来检测浏览器是否处于活动状态并触发您的通知。我猜你可以使用一个可配置的时间间隔来查询状态并阻止你的通知。

代码中的状态是一个回调函数，不是字符串！此代码

setInterval（function（）{ chrome.idle.queryState（15，state）; $ b $ （localStorage.frequency< = interval&& state ==active）{ show（）; interval = 0; } }，60000）;

至

setInterval（function（）{ chrome.idle.queryState（15，function（state）{ if（localStorage.frequency< = interval&& state ==active ）{ show（）; interval = 0; } }）; }，60000）;

I made a Desktop Notification it shows a notification every 1 minute. After 10 second, closes itself.

I gone for a lunch , then computer goes to sleep. When i was back i wake my computer then lots of notification starts.

How can i handle that problem? I want if computer sleeps it shouldnt show notification. How can i control it?

Background.js

function show() { var notification = webkitNotifications.createHTMLNotification( 'notification.html' ); notification.show(); } // Conditionally initialize the options. if (!localStorage.isInitialized) { localStorage.isActivated = true; // The display activation. localStorage.frequency = 1; // The display frequency, in minutes. localStorage.isInitialized = true; // The option initialization. } if (window.webkitNotifications) { // While activated, show notifications at the display frequency. if (JSON.parse(localStorage.isActivated)) { show(); } var interval = 0; // The display interval, in minutes. setInterval(function() { interval++; chrome.idle.queryState(15, state); if(localStorage.frequency <= interval && state=="active") { show(); interval = 0; } }, 60000); }

解决方案

Use Chrome.idle API to detect whether browser is active or not and trigger your notifications. I guess you can use a configurable interval to query state and hold off your notifications.

• Chrome.idle

EDIT 1

The state in your code is a callback function, not a string!, So change this code

setInterval(function () { chrome.idle.queryState(15, state); if (localStorage.frequency <= interval && state == "active") { show(); interval = 0; } }, 60000);

to

setInterval(function () { chrome.idle.queryState(15, function (state) { if (localStorage.frequency <= interval && state == "active") { show(); interval = 0; } }); }, 60000);
