代码

driver = webdriver.Firefox(firefox_profile=profile, options=options)
url = 'https://web.sba.gov/pro-net/search/dsp_dsbs.cfm'
driver.get(url)
delay = 60
checkbox = WebDriverWait(driver, delay).until(
    EC.presence_of_element_located((By.ID, 'EltCbtMin')))

无论我将延迟设置为 3、10 还是 60，大多数时候我都会遇到上面的异常，它在找到元素之前就超时了。显然它有 40% 的时间有效。谁能告诉我哪里出了问题？

点击checkbox associated with text as Any Minority Owned you can use either of the following :

使用css_selector:

driver.get('https://web.sba.gov/pro-net/search/dsp_dsbs.cfm')
driver.find_element(By.CSS_SELECTOR, "input#EltCbtMin[aria-labelledby='LabCbtMin']").click()

使用xpath:

driver.get('https://web.sba.gov/pro-net/search/dsp_dsbs.cfm')
driver.find_element(By.XPATH, "//input[@id='EltCbtMin' and @aria-labelledby='LabCbtMin']").click()

理想情况下，点击你需要诱导的元素WebDriverWait for the and you can use either of the following :

使用CSS_SELECTOR:

driver.get('https://web.sba.gov/pro-net/search/dsp_dsbs.cfm')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#EltCbtMin[aria-labelledby='LabCbtMin']"))).click()

使用XPATH:

driver.get('https://web.sba.gov/pro-net/search/dsp_dsbs.cfm')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='EltCbtMin' and @aria-labelledby='LabCbtMin']"))).click()

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
