在Firefox插件中获取当前的浏览器网址 [英] Getting current browser url in Firefox Addon

问题描述

我在一个面板中，我想获得当前的浏览器URL。目前没有任何工作。这是我测试过的：

唯一能返回任何东西的东西就是 resource：// jid0-18z0ptaugyu0arjkaoywztggyzg-at-jetpack / 然后是我当前的面板资源。显然这是一个范围问题，但我不知道如何引用实际的浏览器。

  window.location.href 
  

我已经尝试了最大的堆栈溢出线程中的所有内容：从Firefox侧边栏扩展中获取当前页面的URL 。

如果有帮助的话，我使用的是Firefox的Addon Builder。

解决方案

  //您需要先使用此服务
 var windowsService = Components.classes ['@ mozilla.org/appshell/window-mediator;1 ] .getService（Components.interfaces.nsIWindowMediator）; 
 
 //表示Firefox最近（活动）实例的窗口对象
 var currentWindow = windowsService.getMostRecentWindow（'navigator：browser'）; 
 
 //最近的（活动的）浏览器对象 - 这是chrome中的文档框架
 var browser = currentWindow.getBrowser（）; 
 
 //包含浏览器中显示地址的所有数据的对象
 var uri = browser.currentURI; 
 
 //在浏览器中显示的实际完整URL的文本表示
 var url = uri.spec; 
  

I within a panel and I want to get the current browser URL. Nothing so far works. Here's what I've tested:

Only thing that even returns anything, I get something like resource://jid0-18z0ptaugyu0arjkaoywztggyzg-at-jetpack/ and then my current panel resource. Obviously this is a scope problem but I don't know how to refer to the actual browser.

window.location.href 

I've tried literally everything in the biggest Stack Overflow thread on this: Get current page URL from a firefox sidebar extension. None of them return anything.

If it helps, I am using the Firefox Addon Builder.

解决方案

// you need to use this service first
var windowsService = Components.classes['@mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator);

// window object representing the most recent (active) instance of Firefox
var currentWindow = windowsService.getMostRecentWindow('navigator:browser');

// most recent (active) browser object - that's the document frame inside the chrome
var browser = currentWindow.getBrowser();

// object containing all the data about an address displayed in the browser
var uri = browser.currentURI;

// textual representation of the actual full URL displayed in the browser
var url = uri.spec;
