Chrome desktop notification click to focus on content
提问by Wade Tandy
I am building desktop notification into my a chrome extension that I am working on. The functionality I need required that the user be taken to the tab that caused the notification when they click on the notification window. I can get that working using the chrome.tabs API, but what I can't manage to figure out is how to bring Chrome to the front when the notification is clicked.
我正在将桌面通知构建到我正在开发的 chrome 扩展中。我需要的功能要求用户在单击通知窗口时被带到导致通知的选项卡。我可以使用 chrome.tabs API 使其工作，但我无法弄清楚如何在单击通知时将 Chrome 置于最前面。
I know window.focus() is disabled in chrome, but this is definitely possible to do since that's the behavior of the Gmail desktop notifications.
我知道 window.focus() 在 chrome 中被禁用，但这绝对是可能的，因为这是 Gmail 桌面通知的行为。

notification = webkitNotifications.createNotification(...)
notification.onclick = function(){
window.focus();
this.cancel();
};
notification.show()
...works as expected, without any additional permissions.
...按预期工作，无需任何额外权限。

Use chrome.tabs.update(tabId, {active: true});to focus a tab (not to be confused with chrome.windows.update).
使用chrome.tabs.update(tabId, {active: true});集中标签（不要与混淆chrome.windows.update）。
The tabIdis often obtained via the Tabtype. This object is passed to many methods/event listeners (sometimes via the MessageSendertype).
在tabId通常通过所获得的Tab类型。这个对象被传递给许多方法/事件侦听器（有时通过MessageSendertype）。

function msg(){
var notification = new Notification("Title", {body: "Yore message", icon: "img.jpg" });
notification.onshow = function() { setTimeout(notification.close(), 15000); };
notification.onclick = function(){
