该 结果是在一个iframe -切换到它，然后得到
.page_source：
iframe = driver.find_element_by_css_selector("#mainContent iframe")driver.switch_to.frame(iframe)我还要添加一个等待表加载的方法：
from selenium.webdriver.common.by import Byfrom selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as ECwait = WebDriverWait(driver, 10)# locate and switch to the iframeiframe = driver.find_element_by_css_selector("#mainContent iframe")driver.switch_to.frame(iframe)# wait for the table to loadwait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '.companyName')))print(driver.page_source)
