如何从iframe中出来并使用Java中的Webdriver单击Logout按钮。在我执行某些操作后的应用程序中，我的应用程序导航到iframe，其中webdriver挂起并且没有错误消息。
我的问题是：我如何走出iframe并点击Logout按钮完成该屏幕的测试。我使用的代码如下：
String msg = driver.findElement(By.xpath(OR.getProperty("CSS_Aggrement_ID"))).getText();
System.out.println(msg);
driver.findElement(By.xpath(OR.getProperty("Chk_Agree_ID"))).click();
//Taking Screen shot of the Application
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("./screenshots\\Admin_Module_Users_"+cdate+"
\\Users\\Exp Fico Addendum screen.jpg"));
Thread.sleep(2000);
System.out.println("@@@@@@@@@@@@");
driver.findElement(By.id(OR.getProperty("btn_Agree_ID"))).click();
driver.switchTo().defaultContent();
Thread.sleep(25000);
System.out.println("Accepted the CREDIT SCORING SERVICES AGREEMENT");
//Logging out the current User
driver.findElement(By.id(OR.getProperty("Logout_ID"))).click();
driver.manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
System.out.println("Logged out of the current User Session.");
使用此行之后，其工作不正常的driver.switchTo（）。defaultContent（）;
请帮我解决这个问题。将不胜感激。
