python Selenium 处理弹出窗口

Question

我正在使用 selenium 单击网站并自动下载，目前我对如何让 selenium 切换到选择下载按钮时创建的弹出窗口感到困惑。简而言之，我想与弹出窗口进行交互，但不熟悉执行此操作的函数/语法或过程。谢谢！

如果找到解决方案，我会更新！

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service as ChromeService
import time

    chrome = 'path'
    url = "url"

    driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))
    driver.get(url)
    driver.maximize_window()

    print("Press CTRL+C to stop program. Close Chrome Browser and stop Chrome Processes in Task Manager")

    iframe = '//*[@id="viz"]/iframe'
    xpath1 = '/html/body/div[2]/div[2]/div[1]/div[2]/div[2]/div[5]/button'
    xpath2 = '/html/body/div[6]/div/div/div/div[2]/div'
    xpath3 = ''

    try:
        iframe = WebDriverWait(driver, 15).until(
            EC.presence_of_element_located((By.XPATH, iframe))
        )
        driver.switch_to.frame(iframe)

        element = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, xpath1))
        )
        element.click()

        element2 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, xpath2))
        )
        element2.click()

    except TimeoutException:
        print("Element not found. Retrying...")
        time.sleep(10)

Answer 1

正如评论中提到的“fiji”，使用带有

move_to_element()

的操作链提供了一种更可靠的与元素交互的方式，特别是在简单点击可能不够的情况下。 根据处理弹出窗口的具体要求调整

try

块内的操作。

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service as ChromeService

chrome = 'path'
url = "url"

driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))
driver.get(url)
driver.maximize_window()

print("Press CTRL+C to stop program. Close Chrome Browser and stop Chrome Processes in Task Manager")

iframe = '//*[@id="viz"]/iframe'
xpath1 = '/html/body/div[2]/div[2]/div[1]/div[2]/div[2]/div[5]/button'
xpath2 = '/html/body/div[6]/div/div/div/div[2]/div'
xpath3 = ''

try:
    iframe = WebDriverWait(driver, 15).until(
        EC.presence_of_element_located((By.XPATH, iframe))
    )
    driver.switch_to.frame(iframe)

    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, xpath1))
    )
    
    # Using Action Chains to click the element
    actions = ActionChains(driver)
    actions.move_to_element(element).click().perform()

    # Now you can handle the pop-up window,
    # Perform actions on the pop-up window as needed
    
finally:
    pass  

# Close the pop-up window
driver.close()

# Switch back to the main window
driver.switch_to.window(driver.window_handles[0])
