mozrepl:进入新打开的窗口时，转到浏览器窗口的上下文

Question

我的问题是，在使用mozrepl创建并进入一个新窗口后，我无法跳转到浏览器窗口上下文，该如何做？

ubugnu@spin-foam:~$ telnet localhost 4242 | tee -a .repl_log
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Welcome to MozRepl.

 - If you get stuck at the "...>" prompt, enter a semicolon (;) at the beginning of the line to force evaluation.
 - If you get errors after every character you type, see http://github.com/bard/mozrepl/wikis/troubleshooting (short version: stop using Microsoft telnet, use netcat or putty instead)

Current working context: chrome://browser/content/browser.xul
Current input mode: syntax

repl> repl.print(document.getElementById('toolbar-menubar'))
[object XULElement]
repl> win = open()
[object Window] - {window: {...}, document: {...}, external: {...}, getInterface: function() {...}, console: {...}, sidebar: {...}, performance: {...}, ...}
repl> repl.enter(win)
[object Window] - {window: {...}, document: {...}, InstallTrigger: {...}, external: {...}, webkitNotifications: {...}, getInterface: function() {...}, console: {...}, ...}
repl> repl.print(document.getElementById('toolbar-menubar'))

repl> repl.print("how to ascend to the browser window context?")

我对mozrepl一点也不熟悉。但从我在您的代码中看到的情况来看，也许您可以尝试使用win.opener来访问当前窗口的打开程序。像这样：

repl.enter(win.opener);

或者，如果您可以访问组件(Cc、Ci、Cu)，则可以尝试访问"navigator:browser“类型的最新窗口：

var window=Cc["@mozilla.org/appshell/window-mediator;1"].getService(Ci.nsIWindowMediator).getMostRecentWindow("navigator:browser");
