javascript - mozrepl: 新しく開いたウィンドウに入るとき、ブラウザ ウィンドウのコンテキストに移動します

Question

私の問題は、mozrepl を使用して新しいウィンドウを作成して入力した後、ブラウザー ウィンドウのコンテキストにアクセスできないことです。

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)
