硒 - 无法找到输入

Question

尝试创建将自动订阅新闻的脚本，但遇到了一个问题，selenium 找不到电子邮件输入和提交按钮。每次收到selenium.common.exceptions.NoSuchElementException:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

chrome_options = Options()
chrome_options.add_argument("--window-size=1920x1080")

path_to_chromedriver = 'chromedriver'
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=path_to_chromedriver)

driver.get('https://dataengweekly.com/')

driver.find_element_by_tag_name("body").send_keys(Keys.PAGE_DOWN)
email_input = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CSS_SELECTOR, 'input[type="email"]'))
)

email_input.send_keys("email@test.com")
driver.find_element_by_css_selector('button.subscribe-btn').click()
time.sleep(10)

Answer 1

注意 - 您的订阅文本框位于不同的 iframe 中，要使用该 iframe，您需要先切换到该 iframe。

试试下面的代码，如果您需要更多说明，请告诉我 -

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver import ActionChains
import time

chrome_options = Options()
chrome_options.add_argument("--window-size=1920x1080")

driver = webdriver.Chrome(options=chrome_options)

wait = WebDriverWait(driver, 5)
action = ActionChains(driver)

driver.get('https://dataengweekly.com/')

iframe = driver.find_element_by_xpath('//iframe')
driver.switch_to.frame(iframe)

email_input = wait.until(EC.presence_of_element_located((By.XPATH, "//input[@type='email']")))
action.move_to_element(email_input).click().send_keys("email@test.com").perform()

driver.find_element_by_css_selector('button.subscribe-btn').click()
time.sleep(2)
