如何使用 Java 处理 Selenium WebDriver 中的新窗口？

How to handle the new window in Selenium WebDriver using Java?

提问by Arun Kumar

This is my code:

这是我的代码：

driver.findElement(By.id("ImageButton5")).click();
//Thread.sleep(3000);
String winHandleBefore = driver.getWindowHandle();
driver.switchTo().window(winHandleBefore);
driver.findElement(By.id("txtEnterCptCode")).sendKeys("99219");

Now I have the next error:

现在我有下一个错误：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to find element with id == txtEnterCptCode (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 404 milliseconds.

线程“main” org.openqa.selenium.NoSuchElementException 中的异常：无法找到 id == txtEnterCptCode 的元素（警告：服务器未提供任何堆栈跟踪信息）命令持续时间或超时：404 毫秒。

Any ideas?

有任何想法吗？

It seems like you are not actually switching to any new window. You are supposed get the window handle of your original window, save that, then get the window handle of the new window and switch to that. Once you are done with the new window you need to close it, then switch back to the original window handle. See my sample below:

看起来您实际上并没有切换到任何新窗口。您应该获取原始窗口的窗口句柄，保存它，然后获取新窗口的窗口句柄并切换到该窗口句柄。完成新窗口后，您需要关闭它，然后切换回原始窗口句柄。请参阅下面的示例：

i.e.

IE

String parentHandle = driver.getWindowHandle(); // get the current window handle
driver.findElement(By.xpath("//*[@id='someXpath']")).click(); // click some link that opens a new window

for (String winHandle : driver.getWindowHandles()) {
    driver.switchTo().window(winHandle); // switch focus of WebDriver to the next found window handle (that's your newly opened window)
}

//code to do something on new window

driver.close(); // close newly opened window when done with it
driver.switchTo().window(parentHandle); // switch back to the original window

I have an utility method to switch to the required window as shown below

我有一个实用方法可以切换到所需的窗口，如下所示

public class Utility 
{
    public static WebDriver getHandleToWindow(String title){

        //parentWindowHandle = WebDriverInitialize.getDriver().getWindowHandle(); // save the current window handle.
        WebDriver popup = null;
        Set<String> windowIterator = WebDriverInitialize.getDriver().getWindowHandles();
        System.err.println("No of windows :  " + windowIterator.size());
        for (String s : windowIterator) {
          String windowHandle = s; 
          popup = WebDriverInitialize.getDriver().switchTo().window(windowHandle);
          System.out.println("Window Title : " + popup.getTitle());
          System.out.println("Window Url : " + popup.getCurrentUrl());
          if (popup.getTitle().equals(title) ){
              System.out.println("Selected Window Title : " + popup.getTitle());
              return popup;
          }

        }
                System.out.println("Window Title :" + popup.getTitle());
                System.out.println();
            return popup;
        }
}

It will take you to desired window once title of the window is passed as parameter. In your case you can do.

一旦窗口的标题作为参数传递，它将带您到所需的窗口。在你的情况下，你可以做到。

Webdriver childDriver = Utility.getHandleToWindow("titleOfChildWindow");

and then again switch to parent window using the same method

然后再次使用相同的方法切换到父窗口

Webdriver parentDriver = Utility.getHandleToWindow("titleOfParentWindow");

Webdriver parentDriver = Utility.getHandleToWindow("titleOfParentWindow");

This method works effectively when dealing with multiple windows.

这种方法在处理多个窗口时有效。

I have a sample program for this:

我有一个示例程序：

public class BrowserBackForward {

公共类 BrowserBackForward {

/**
 * @param args
 * @throws InterruptedException 
 */
public static void main(String[] args) throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://seleniumhq.org/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    //maximize the window
    driver.manage().window().maximize();

    driver.findElement(By.linkText("Documentation")).click();
    System.out.println(driver.getCurrentUrl());
    driver.navigate().back();
    System.out.println(driver.getCurrentUrl());
    Thread.sleep(30000);
    driver.navigate().forward();
    System.out.println("Forward");
    Thread.sleep(30000);
    driver.navigate().refresh();

}

}

}

                string BaseWindow = driver.CurrentWindowHandle;
                ReadOnlyCollection<string> handles = driver.WindowHandles;
                foreach (string handle in handles)
                {
                    if (handle != BaseWindow)
                    {
                        string title = driver.SwitchTo().Window(handle).Title;
                        Thread.Sleep(3000);
                        driver.SwitchTo().Window(handle).Title.Equals(title);
                        Thread.Sleep(3000);
                    }
                }

Set<String> windows = driver.getWindowHandles();
Iterator<String> itr = windows.iterator();

//patName will provide you parent window
String patName = itr.next();

//chldName will provide you child window
String chldName = itr.next();

//Switch to child window
driver.switchto().window(chldName);

//Do normal selenium code for performing action in child window

//To come back to parent window
driver.switchto().window(patName);

i was having some issues with windowhandle and tried this one. this one works good for me.

我在使用 windowhandle 时遇到了一些问题并尝试了这个。这个对我很有用。

String parentWindowHandler = driver.getWindowHandle(); 
String subWindowHandler = null;

Set<String> handles = driver.getWindowHandles();
Iterator<String> iterator = handles.iterator();
while (iterator.hasNext()){
    subWindowHandler = iterator.next();
    driver.switchTo().window(subWindowHandler);

    System.out.println(subWindowHandler);
}


driver.switchTo().window(parentWindowHandler);
