在弹出窗口中输入文本，找不到带有 Python 硒的元素

Question

我试图在弹出窗口中的用户名和密码框中输入一些文本 https://fantasy.espn.com/football/players/add?leagueId=1

我假设有一个弹出窗口，所以我相信我切换到了它。我找不到任何可以选择的元素。我试过做

driver.find_element_by_xpath("//input[@type='email']")

或

driver.find_element_by_xpath("//input[@placeholder='Username or Email Address']")

两次我都收到错误，指出找不到元素：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Chrome()
driver.get("https://fantasy.espn.com/football/players/add?leagueId=1")
time.sleep(15)
driver.find_element_by_xpath("//input[@placeholder='Username or Email Address']")

Answer 1

弹出窗口正在iframe内加载。您必须首先切换到 iframe，然后使用 xpath 或其他选择器查找其余字段。

from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = Chrome('drivers/chromedriver')
driver.get('https://fantasy.espn.com/football/players/add?leagueId=1')
iframe_xpath = '//*[@id="disneyid-iframe"]'
iframe = WebDriverWait(driver, 30).until(
EC.element_to_be_clickable(
(By.XPATH, iframe_xpath)
)
)
driver.switch_to_frame(iframe)
username_field = driver.find_element_by_xpath("//input[@type='email']")
password_field = driver.find_element_by_xpath("//input[@type='password']")
login_button = driver.find_element_by_xpath(
'//*[@id="did-ui-view"]/div/section/section/form/section/div[3]/button'
) 
username_field.send_keys('username')
password_field .send_keys('password')
login_button.click()
