我正在使用带有 Selenium 2 的 Robotframework 并尝试在 Firefox 上执行 Javascript。我尝试了很多不同的语句，例如：

Execute Javascript    (function(){alert('hello'); return {'test':'hello'};})()

但他们都失败了，但同样的例外。我只对 Firefox（22 和 23）有问题，但 Chrome 很好。这是我在使用 pybot --loglevel debug 运行时在 log.html 中看到的内容。

    raise exception_class(message, screen, stacktrace)

如果我进入 webdriver.py 并注释掉该行

self.error_handler.check_response(response)

然后测试通过了，但我仍然没有真正让 javascript 执行。

另一个更新 - 我发现这个问题只影响 Firefox 22 和 23。如果我回到 Firefox 21，那么它工作正常。

当我尝试时：

Execute Javascript    (function(){alert('hello'); return {'test':'hello'};})()

我在 Firefox 35 中看到了警报弹出窗口
