未选择日历元素-Selenium Webdriver

Question

我有困难选择一个特定的日期使用日期选择器。下面是我尝试这样做的代码：

String parentWindow = driver.getWindowHandle();
String subWindow = null;
driver.findElement(By.xpath(".//*[@id='ns_7_CO19VHUC6VU280AQ4LUKRK0IR7_fmOutboundDateDisplay']")).click(); //Clicking on datepicker icon

// Change to a new window
String parentWindow = driver.getWindowHandle();
String subWindow = null;
Set<String> handles = driver.getWindowHandles(); // get all window handles
Iterator<String> iterator1 = handles.iterator();
while (iterator.hasNext()){
    subWindow = iterator.next();
}
driver.switchTo().window(subWindow);
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
driver.findElement(By.xpath("//*[@class='calendarBodyContainer']/tr[2]/td[3]/span")).click(); //Departure Date- 10Feb/2015
driver.findElement(By.xpath(".//*[@class='calendarBodyContainer']/tr[4]/td[4]/span")).click(); //Arrival Dtae- 25 Feb/2015
driver.switchTo().window(parentWindow);

然而，我得到以下错误：

线程“main”org.openqa.selenium.nosuchelementException：找不到元素：{“method”：“XPath”,“selector”：“//*[@class='calendar bodycontainer']/tr[2]/td[3]/span”}命令持续时间或超时：3.12秒

请帮帮忙。

问题是您错误地将calendar小部件当成了新的窗口，并相应地进行了自动操作，这导致未找到该元素，这是@Alecxe正确地怀疑的

请尝试下面的代码，看看它是否适合您。

WebDriver driver=new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

//Navigating to the site
driver.get("http://www.lufthansa.com/online/portal/lh/us/homepage");

//Clicking on the Departing field to select date
driver.findElement(By.id("ns_7_CO19VHUC6VU280AQ4LUKRK0IR7_fmOutboundDateDisplay")).click();

//Selecting Feb 10, 2015 for departure date 
driver.findElement(By.xpath("//td[@dojoattachpoint = 'calRightNode']//span[.='10']")).click();

//Waiting for the return calendar with "Return" as the header to appear
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@dojoattachpoint='calHeadlineNode' and contains(text(),'Return')]")));

//Selecting Feb 26, 2015 for returning date
driver.findElement(By.xpath("//td[@dojoattachpoint = 'calLeftNode']//span[.='26']")).click();

注意：我在“Return Calendar widget”中添加了显式wait for waiting for Return文本，因为它与离开/出站日历重叠，因此selenium需要一点时间来检测DOM中的更改。
