python - 如何关闭一个选项卡，然后使用 selenium 转到另一个选项卡？

Question

这是一个示例脚本：

from selenium import webdriver

driver = webdriver.Firefox()

driver.get('https://www.startpage.com/en/')

driver.find_element_by_xpath('//*[@id="query"]').send_keys('Example')

driver.find_element_by_xpath('/html/body/div[1]/main/div[1]/section/div[1]/div[1]/form/button[2]/span[2]').click()

driver.find_element_by_xpath('/html/body/div[2]/div/div[2]/div[1]/div[2]/div[1]/div/section[5]/div[1]/a/h3').click()

最后，它单击打开一个新选项卡的内容。我想关闭新标签并继续使用原始标签

标签： pythonseleniumselenium-webdriverwindow-handles

Answer 1

要关闭新选项卡并继续使用原始选项卡，您必须：

• 切换到新选项卡，为和引入WebDriverWait。number_of_windows_to_be(2)close()

• 切换回父选项卡。

  • 代码块：

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support import expected_conditions as EC
    
    options = webdriver.ChromeOptions() 
    options.add_argument("start-maximized")
    options.add_experimental_option("excludeSwitches", ["enable-automation"])
    options.add_experimental_option('useAutomationExtension', False)
    driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
    
    driver.get('https://www.startpage.com/en/')
    print("Initial Page Title is : %s" %driver.title)
    windows_before  = driver.current_window_handle
    print("First Window Handle is : %s" %windows_before)
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.search-form__input"))).send_keys("Example")
    driver.find_element_by_css_selector("span.search-form__button-icon").click()
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//h3[@class='w-gl__label']//following::h3[1]"))).click()
    WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
    windows_after = driver.window_handles
    new_window = [x for x in windows_after if x != windows_before][0]
    driver.switch_to.window(new_window)
    print("Page Title after Tab Switching is : %s" %driver.title)
    print("Second Window Handle is : %s" %new_window)
    driver.close()
    driver.switch_to.window(windows_before)
    print("Page Title after second Tab Switching is : %s" %driver.title)
    print("Current Window Handle is : %s" %windows_before)
    

  • 控制台输出：

    Initial Page Title is : Startpage.com - The world's most private search engine
    First Window Handle is : CDwindow-18CCC5501A5F68CBE1C3094D0D0B419D
    Page Title after Tab Switching is : YouTube
    Second Window Handle is : CDwindow-2EDCAB04A232660E8BCBD7A079DE574B
    Page Title after second Tab Switching is : Startpage.com Search results
    Current Window Handle is : CDwindow-18CCC5501A5F68CBE1C3094D0D0B419D
