Windows处理会关闭整个浏览器,如果我尝试在python中关闭当前窗口

标签: python selenium selenium-webdriver webdriverwait window-handles

目前我正在使用Windows处理在新窗口中打开地图方向,然后在打开后我将关闭子窗口,该子窗口已打开并在代码中进行了重命名工作,但是它将关闭整个浏览器,而调试它可以正常工作,但是在运行代码时,正在获取错误,

错误-selenium.common.exceptions.NoSuchWindowException: Message: no such window: target window already closed

我已经附加了代码,

   ##Clicking on The Map Image
            self.driver.find_element_by_xpath("/html[1]/body[1]/div[1]/div[2]/div[1]/section[1]/div[1]/div[1]/div[2]/div[1]/a[1]/img[1]").click()
            ##Setting up an Window Handle to get the size.
            handels =self.driver.window_handles
            size = len(handels)
            """
            The Below For Loop, We are using For Handling The Mutilple Windows,
            Which are opened in the Browser.
            """

            for length in range(size):
                driver.switch_to.window(handels[length])
                print(self.driver.title)
                time.sleep(3)
                if length == 1:
                    driver.close()

我做过错误的地方不知道。请把我整理一下。

尝试使用此代码关闭新窗口并切换回主窗口

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Get current window
current = self.driver.current_window_handle
# Get current windows
handles = self.driver.window_handles
# Click button. Consider to use more reliable relative XPath instead of this absolute XPath
self.driver.find_element_by_xpath("/html[1]/body[1]/div[1]/div[2]/div[1]/section[1]/div[1]/div[1]/div[2]/div[1]/a[1]/img[1]").click()
# Wait for new window
WebDriverWait(self.driver, 10).until(EC.new_window_is_opened(handles))
# Switch to new window
self.driver.switch_to.window([w for w in self.driver.window_handles if w != current][0])
# Close new window
self.driver.close()
# Switch back to main window
self.driver.switch_to.window(current)

简而言之,切换到新窗口句柄并不干净。

解决方案

  • 始终跟踪父窗口句柄,以便以后根据需要根据需要进行遍历。
  • 标签/ Windows 之间切换之前,始终将WebDriverWaitexpected_conditions用作number_of_windows_to_be(num_windows)
  • 始终跟踪子窗口句柄,以便您可以在需要时遍历。
  • 在提取页面标题之前,始终将expected_conditions作为title_contains("partial_page_title")使用 WebDriverWait
  • 这是您自己的代码,上面有一些小的调整:

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    
    handels_initially  = driver.window_handles
    self.driver.find_element_by_xpath("/html[1]/body[1]/div[1]/div[2]/div[1]/section[1]/div[1]/div[1]/div[2]/div[1]/a[1]/img[1]").click()
    WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
    handels_now =self.driver.window_handles
    new_handle = [x for x in handels_now if x != handels_initially][0]
    driver.switch_to.window(new_handle)
    WebDriverWait(driver, 20).until(EC.title_contains("partial_title"))
    print(self.driver.title)
    driver.close()
