Python Selenium 检查复选框：selenium.common.exceptions.NoSuchElementException：消息：没有这样的元素：无法定位元素

Question

我已经编写了代码来选择以下网站上的复选框： https : //www.theatlantic.com/do-not-sell-my-personal-information/

我尝试过以下版本：版本 1：

ele = driver.find_element_by_id('residency') driver.execute_script("arguments[0].click()",ele)

版本 2: checkBox1 = driver.find_element_by_css_selector("input[id='residency']")

版本 3： driver.find_element_by_xpath("//input[@type='checkbox']")

但是，对于所有这些版本，我收到以下错误：

Traceback (most recent call last):
  File "website-functions/theatlantic.py", line 43, in <module>
    atlantic_DD_formfill(california_resident, email, zipcode)
  File "website-functions/theatlantic.py", line 30, in atlantic_DD_formfill
    driver.find_element_by_xpath("//input[@type='checkbox']")
  File "/usr/local/lib/python3.6/dist-packages/selenium/webdriver/remote/webdriver.py", line 394, in find_element_by_xpath

Answer 1

页面上有一个 iframe，因此您需要先切换到该 iframe，然后单击该元素，因为另一个元素放置在复选框元素上方，您需要使用 java 脚本 click 方法单击复选框。
你可以这样做：

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import os
import time
def atlantic_DD_formfill(california_resident, email, zipcode):
    chrome_options = Options()
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--disable-dev-shm-usage')
    chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
    chrome_options.add_experimental_option('useAutomationExtension', False)
    driver = webdriver.Chrome(options=chrome_options)
    driver.set_page_load_timeout(10)
    driver.set_window_size(1124, 850) # set browser size
    # link to data delete form
    print("opening data delete form")
    driver.get("https://www.theatlantic.com/do-not-sell-my-personal-information/")
    driver.switch_to.frame(driver.find_element_by_tag_name('iframe'))
    element = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, "//input[@type='checkbox']")))
    driver.execute_script("arguments[0].click();", element)
