Safari 5扩展：如何检测窗口当前选项卡何时更改？ [英] Safari 5 Extension: How can I detect when a window's current tab has changed?

问题描述

我有一个包含工具栏的Safari 5扩展。每当当前选项卡更改时，该工具栏应该更新。我想从我的酒吧的脚本中做这样的事情：

  safari.self.browserWindow.addEventListener（activeTab，tabChanged ，假）; 
  

但是，似乎不起作用。我也尝试了一些其他事件名称：

• activeTab


• activeTabChanged


• onActiveTab


• onActiveTabChanged


• 标签


• tabChanged


• onTab


• onTabChanged


• selectionChanged


• onSelectionChanged

有人知道如何检测活动标签何时更改？

不是这样，相关的，但是看起来我会在Chrome中执行此操作：

  chrome.tabs.onSelectionChanged.addListener（tabChanged）; 
  

解决方案

Safari 5.1有几个新的扩展事件，包括当窗口或标签集中时，激活事件触发。

I have a Safari 5 extension that contains a toolbar. Whenever the current tab changes, that toolbar should be updated. I would like to do something like this from my bar's script:

safari.self.browserWindow.addEventListener("activeTab", tabChanged, false);

However, that doesn't seem to work. I have tried a number of other event names as well:

• activeTab
• activeTabChanged
• onActiveTab
• onActiveTabChanged
• tab
• tabChanged
• onTab
• onTabChanged
• selectionChanged
• onSelectionChanged

Does anybody know how to detect when the active tab changes?

Not that this is in any way related, but it looks like I would do this in Chrome with:

 chrome.tabs.onSelectionChanged.addListener(tabChanged);

解决方案

Safari 5.1 has several new events for extensions, including an "activate" event that fires when a window or tab is focused.
