我正在尝试创建一个 python + selenium 脚本，以便从 salesforce pardot 页面获取 CSV。

有人可以帮助我访问下拉列表中的嵌套跨度元素，该元素将在单击按钮时生成。

到目前为止，我正在添加我的代码，并且在运行我的脚本时出现超时错误。

from selenium import webdriver
import time
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 import webdriver
try:
    chrome_options = webdriver.ChromeOptions()
    prefs = {'download.default_directory': r'C:\Pardot'}
    chrome_options.add_experimental_option('prefs', prefs)
    driver = webdriver.Chrome(executable_path="D:\XXX XXXX\XXXX\drivers\chromedriver.exe", options=chrome_options)
    driver.get('https://pi.pardot.com/engagementStudio/studio#/15627/reporting')
    user_name = driver.find_element_by_css_selector('#email_address')
    user_name.send_keys('XXXXXXXXXXXXXXXXXXX')
    password = driver.find_element_by_css_selector('#password')
    password.send_keys('XXXXXXXXXXXXXXXXX)
    submit_button = driver.find_element_by_css_selector('input.btn')
    submit_button.click()
    WebDriverWait(driver, 10).until(
    EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR, "iframe#content-frame")))
    WebDriverWait(driver, 10).until(EC.text_to_be_present_in_element_value(text_='All Time',locator=(By.CSS_SELECTOR,"span[data-qa='reporting-filter-trigger-value']")))

except (RuntimeError) as e:
    print(e)
finally:
    time.sleep(10)
    driver.close()

试试这个方法

spans = driver.find_element_by_css_selector('.slds-button_reset.slds-grow.slds-has-blur-focus.trigger-button').get_attribute('innerHTML') print(spans) 你应该得到所有的跨度。
