mozrepl：在新打開的窗口中輸入時轉到瀏覽器窗口的上下文

Question

我的問題是，使用mozrepl創建並進入新窗口后，無法提升到瀏覽器窗口上下文，該怎么辦？

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

我一點都不熟悉mozrepl 。 但是從我在您的代碼中看到的來看，也許您可​​以嘗試使用win.opener來訪問您當前所在窗口的打開器。例如：

repl.enter(win.opener);

另外，如果可以訪問組件（Cc，Ci，Cu），則可以嘗試訪問“ navigator：browser”類型的最新窗口：

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