Python and WebDriver Extension: Switching Windows in a Web Page

Introduction:
In web application testing, it is often necessary to switch between different browser windows. Python and its WebDriver extension provide a simple and convenient way to achieve this goal. This article will introduce how to use Python and WebDriver extensions to switch windows in web pages, as well as some common application scenarios.

1. Get the handle of the current window:
Before using WebDriver to open a new window, we need to get the handle of the current window so that we can switch back to the original window when needed. Python's WebDriver extension provides a method to obtain the handle of the current window. The sample code is as follows:

from selenium import webdriver

# 创建一个新的WebDriver实例
driver = webdriver.Chrome()

# 获取当前窗口的句柄
current_handle = driver.current_window_handle

# 打印当前窗口的句柄
print("当前窗口句柄为：", current_handle)

2. Open a new window and switch to it:
You may need to open a new window during testing new window and perform some operations in the new window. Python's WebDriver extension provides a method to open a new window and switch focus to that window. The sample code is as follows:

from selenium import webdriver

# 创建一个新的WebDriver实例
driver = webdriver.Chrome()

# 打开新窗口
driver.execute_script("window.open('about:blank');")

# 切换到新窗口
driver.switch_to.window(driver.window_handles[1])

3. Switch back to the original window:
After completing some operations in the new window, we may need to switch back to the original window to continue other tests. Python's WebDriver extension provides a way to switch back to the original window. The sample code is as follows:

from selenium import webdriver

# 创建一个新的WebDriver实例
driver = webdriver.Chrome()

# 获取当前窗口的句柄
current_handle = driver.current_window_handle

# 打开新窗口
driver.execute_script("window.open('about:blank');")

# 切换到新窗口
driver.switch_to.window(driver.window_handles[1])

# 在新窗口中进行一些操作

# 切换回原始窗口
driver.switch_to.window(current_handle)

Conclusion:
By using Python and WebDriver extensions, we can easily switch windows in web pages. This article explains how to get the current window handle, open a new window and switch to that window, and how to switch back to the original window. Mastering these skills can help us better conduct web application testing and improve testing efficiency. I hope this article will be helpful to your learning and practice of switching windows in Python and WebDriver extensions.
