当测试页面同时出现2个或者以上窗口时候，而且新打开的window没有namem,可以使用driver.switchTo().window(winHandleID)来进行切换，如下代码已经在IE8中测试通过：

//Store the current window handleString winHandleBefore = driver.getWindowHandle();		//Switch to new window openedfor(String winHandle : driver.getWindowHandles()){	    	System.out.println("+++" + winHandle);	        driver.switchTo().window(winHandle);	        }// Close the original window	    driver.switchTo().window(winHandleBefore);	    driver.close();	    //Switch to new window openedfor(String winHandle : driver.getWindowHandles()){	    	System.out.println("+++" + winHandle);	        driver.switchTo().window(winHandle);	        }

当最后只有一个窗口剩下的时候，应该可以直接使用

driver.switchTo().window(driver.getWindowHandle)

去选中新的窗口

public boolean switchToWindow(WebDriver driver,String windowTitle){		boolean flag = false;		try {			String currentHandle = driver.getWindowHandle();			Set
     
       handles = driver.getWindowHandles();			for (String s : handles) {				if (s.equals(currentHandle))					continue;				else {					driver.switchTo().window(s);					if (driver.getTitle().contains(windowTitle)) {						flag = true;						System.out.println("Switch to window: "								+ windowTitle + " successfully!");						break;					} else						continue;				}			}		} catch (NoSuchWindowException e) {			System.out.println("Window: " + windowTitle					+ " cound not found!", e.fillInStackTrace());			flag = false;		}		return flag;	}
