使用 Selenium 从下拉列表中选择项目

Question

我正在尝试使用 Selenium 从下拉列表中选择不同的元素，但遇到以下错误消息：

NoSuchElementException Traceback（最近调用 最后）在 21 驱动程序.get(next_url) 22 ---> 23 sel = Select(driver.find_element_by_xpath('//*[@id="j_id23:j_id44"]')) 24 25 sel.select_by_visible_text("A CORUÑA")

next_url = "https://www.abogacia.es/servicios-abogacia/censo-de-letrados/"

driver = webdriver.Chrome(ChromeDriverManager().install())

driver.get(next_url)

sel = Select(driver.find_element_by_xpath('//*[@id="j_id23:j_id44"]'))
    
sel.select_by_visible_text("A CORUÑA")
        
wait = WebDriverWait(driver, 5)
button = wait.until(presence_of_element_located((By.XPATH, '//*[@id="j_id23:idBuscar"]')))
button.click()
    
time.sleep(1)
    
abogados = driver.find_element_by_class_name(' iceRowSelMouseOver')
        
print(abogados)

Answer 1

这里有几个问题：

1. 您错过了延迟/之前的等待

driver.find_element_by_xpath('//*[@id="j_id23:j_id44"]')

你应该在那里添加一个等待，像这样：

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

wait = WebDriverWait(driver, 20)

wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="j_id23:j_id44"]')))
sel = Select(driver.find_element_by_xpath('//*[@id="j_id23:j_id44"]'))

1. 您的定位器似乎有误。
   我无法访问该页面，但 '//*[@id="j_id23:j_id44"]' 似乎不是一个稳定的 XPath 表达式

Answer 2

您尝试访问的元素位于框架内。通过

切换到框架

driver.switch_to.frame(driver.find_element_by_xpath(".//iframe[contains(@src,'homeColegiados')]"))


select = Select(driver.find_element_by_xpath(".//select[@class='iceSelOneMnu']"))
select.select_by_visible_text("A CORUÑA")
