title: Handling Alert/Confirm with JavascriptExecutor in Selenium GhostDriver
body: <p>I'm getting desperate. I'm using Selenium 2.42.2 with the phantomjsDriver 1.1.0 with Java in Eclipse. For my test it is essential that I recognize and store messages of Alerts and Confirms and maybe Prompts when I open a Page. The phantomjsDriver does not implement it yet, so I need a workaround with the JavascriptExecutor. But I am a js noob and can't manage it alone. Here my code and what I tried:    </p>
  
  <pre><code>DesiredCapabilities dcaps = new DesiredCapabilities();
  String[] phantomArgs = new  String[] {
          "--webdriver-loglevel=NONE"};
  dcaps.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
  dcaps.setCapability(CapabilityType.SUPPORTS_ALERTS, true);
  dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, 
          phantomjs.getAbsolutePath());
  dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, phantomArgs);
  dcaps.setJavascriptEnabled(true);
  WebDriver driver = new PhantomJSDriver(dcaps);
  
  JavascriptExecutor js=(JavascriptExecutor) driver;
  String script = "window.confirm = function(message) {"+
          "document.lastConfirmationMessage = message; return true; }";
  js.executeScript(script);
  driver.get("http://www.mysiteWithConfirm.de"); 
  Object message = js.executeScript("return document.lastConfirmationMessage");
  </code></pre>
  
  <p>When I open my site, it opens immediately the Confirm prompt so I know there is a Confirm. But I just get exceptions</p>
  
  <blockquote>
    <p>Error Message => 'Can't find variable: lastConfirmationMessage'</p>
  </blockquote>
