硒无法在iframe中找到字典元素

亚当·戴维斯

Selenium不可思议。我正在尝试使用它来“填写”网络表单，以便最终我可以在Python中以字典的形式获得结果。到目前为止，我有

from selenium.webdriver.common.keys import Keys
from time import sleep

driver = webdriver.Chrome()
driver.get("https://my.crawley.gov.uk/en/service/check_my_bin_collection?accept=yes&consentMessageIds[]=24")
sleep(5)
assert "Check bin collections" in driver.title
elem = driver.find_element_by_id('PostcodeSearch')
elem.clear()
elem.send_keys("RH10 7AB")
elem.send_keys(Keys.RETURN)
driver.close()

但是无论我选择哪种方法，我都在努力获取页面上的元素

该邮政编码字段内的<iframe>，所以你必须：

诱导WebDriverWait获得所需的帧并切换到该帧。
诱导WebDriverWait使所需的元素可单击。
您可以使用以下定位策略之一：

使用CSS_SELECTOR：

driver.get('https://my.crawley.gov.uk/en/service/check_my_bin_collection?accept=yes&consentMessageIds[]=24')
elem = WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='Check bin collections']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#PostcodeSearch")))
elem.send_keys("RH10 7AB")

使用XPATH：

driver.get("https://my.crawley.gov.uk/en/service/check_my_bin_collection?accept=yes&consentMessageIds[]=24")
elem = WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@title='Check bin collections']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='PostcodeSearch']")))
elem.send_keys("RH10 7AB")

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
