Windows处理如果我尝试在python中关闭当前窗口,则关闭整个浏览器

问题描述 投票:0回答:2

我目前正在使用Windows处理在新窗口中打开地图方向,打开后我将关闭子窗口,该窗口打开并在代码中进行重新映射工作。但它关闭整个浏览器,而调试它是工作正常,但在运行代码时,我得到错误,

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

我已经附上了代码,

   ##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()

在哪里我做错了我不知道。请把我解雇。

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,切换到新窗口手柄并不干净。

  • 始终跟踪父窗口句柄,以便稍后根据您的用例进行遍历。
  • 在切换Tabs / Windows之前,务必使用WebDriverWaitexpected_conditions作为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进行遍历。
  • 在提取页面标题之前,始终使用带有expected_conditions的WebDriverWait作为title_contains("partial_page_title")
  • 这是您自己的代码,上面提到了一些小调整: 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()
