检测选项卡关闭（关闭后）从Firefox扩展 [英] Detecting tab closed (after closed) from firefox extension

问题描述

我试图让我的Firefox扩展从浏览器中的所有选项卡创建一个URL列表。为了保持列表更新，我需要知道何时关闭标签。

我试过使用

  window.addEventListener（TabClos​​e，tabRemoved，false）; 
  

然而，这个被调用之前tab实际上是关闭的，这导致我的更新tablist仍然包含关闭标签网址。

我通过迭代所有浏览器更新标签列表，如下所示：

  function（）
 {
 gBrowser = window.getBrowser（）; 
 tabs = gBrowser.browsers; 
 urls = []; 
 
 for（var i = 0; i< tabs.length; i ++）
 {
 if（typeof（tabs [i]）！=undefined）{
 urls.push（tabs [i] .webNavigation.currentURI.spec）; 
} 
} 
 
返回网址; 
 
 
 
 
 
 $ b 
所以我要找的是一个事件，已关闭，或者获取已关闭的选项卡的索引，以便在迭代浏览器时跳过它。
 
 
 
任何人都知道任何此类事件或其他解决方案给我的问题？
 
 
提前致谢！  
解决方案
是我做了什么来解决这个问题：
 
 $ pre $ tab $移动=函数$ ev 
 $ $ $ logTabs（ [ev.target._tPos]）; / * ev.target._tPos =关闭标签的索引* / 
} 
 
 logTabs =函数（excludedelist）
 {
 ... 
 urls = getTabURLs（）; $（i = 0; i  {
 if（typeof（excludelist）！=undefined&&& excludelist.indexOf ！= -1）
 continue; 
 
 doStuff（urls [i]）; 
 ... 
  

I'm trying to get my firefox extension to create a url list from all tabs in the browser. To keep the list updated I need to know when a tab has been closed.

I've tried using

window.addEventListener("TabClose", tabRemoved, false);

However, this gets called BEFORE the tab is actually closed, which results in my updated tablist still containing the closed tabs url.

I update the tab list by iterating all browsers, like so:

function ()
{
    gBrowser = window.getBrowser();
    tabs = gBrowser.browsers;
    urls = [];

    for (var i = 0; i < tabs.length; i++)
    {
        if (typeof(tabs[i]) != "undefined") {
            urls.push(tabs[i].webNavigation.currentURI.spec);
        }
    }

    return urls;
}

So what I'm looking for is an event that gets called AFTER a tab has been closed, or a way to get the index of the tab that was closed so that I can skip it while iterating browsers.

Anyone know of any such event or other solutions to my problem?

Thanks in advance!

解决方案

Here is what I did to solve the problem:

tabRemoved = function (ev)
{
    logTabs([ev.target._tPos]); /* ev.target._tPos = index of tab that was closed */
}

logTabs = function (excludelist)
{
    ...
    urls = getTabURLs();
    for(var i = 0; i < urls.length; i++)
    {
        if(typeof(excludelist) != "undefined" && excludelist.indexOf(i) != -1)
            continue;

        doStuff(urls[i]);
    ...
