Selenium切换标签页报错：NoneType无find_element属性及交互异常

DevOps 小满

2026-7-21

问题描述

我需要实现以下逻辑：当Excel中Mat列的数据以"S"开头（如S9335）时，将其替换为900开头（即9009335），在目标网站查询并提取NIT结果；若不以"S"开头则直接查询。编写Python代码后遇到两个错误，请求解决。

原始代码

options = Options()
options.add_argument("start-maximized")
webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service, options=options)
websites = ['https://www.rues.org.co/RM','https://www.rues.org.co/ESAL']

Mat_column= 'Mat'
value='01'
excel_file_path=r'C:\Users\Hi\Documents\Project\output\164115.xlsx'

driver.get(websites[0])


df=pd.read_excel(excel_file_path, dtype=str)

NIT=[]

for i in df.index: 

    entry=df.loc[i]
   
    if entry[Mat_column].startswith('S'):

        new_entry=entry[Mat_column].replace('S','900')
        
        driver.execute_script("window.open('');")
        driver.switch_to.window(driver.window_handles[1])
        d1=driver.get(websites[1])

        cam = Select(d1.find_element(By.XPATH, '//*[@id="codCamara"]'))
        cam.select_by_value(value)

        driver.find_element(By.LINK_TEXT, 'Matrícula / Inscripción').click()

        time.sleep(3)
         
        mat = driver.find_element(By.XPATH,'//*[@id="txtSearchMat"]')
        consult = driver.find_element(By.XPATH,'//*[@id="btnConsultaMat"]')

        mat.send_keys(new_entry)
        consult.click()
        mat.send_keys(Keys.CONTROL + "a")

        try:
            nit = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="rmTable2"]/tbody/tr/td[3]'))).text
            NIT.append(nit)
        except:
            NIT.append("0")

    else:
        driver.execute_script("window.open('');")
        driver.switch_to.window(driver.window_handles[1])

        cam = Select(d1.find_element(By.XPATH, '//*[@id="codCamara"]'))
        cam.select_by_value(value)

        driver.find_element(By.LINK_TEXT, 'Matrícula / Inscripción').click()

        mat = driver.find_element(By.XPATH,'//*[@id="txtSearchMat"]')
        consult = driver.find_element(By.XPATH,'//*[@id="btnConsultaMat"]') 

        mat.send_keys(entry[Mat_column])
        consult.click()
        mat.send_keys(Keys.CONTROL + "a")

        try:
            nit = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="rmTable2"]/tbody/tr/td[3]'))).text
            NIT.append(nit)
        except:
            NIT.append("0")

DATANIT=pd.DataFrame(
    {   
        'NIT' : NIT,
    }
)

print(DATANIT)

遇到的错误

第一个错误

运行代码时触发：

cam = Select(d1.find_element(By.XPATH, '//*[@id="codCamara"]'))
                    ^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'find_element'

第二个错误

将代码中的d1替换为driver后，出现新错误：

解决方案

1. 修复第一个错误：`d1`为`NoneType`

driver.get()方法没有返回值，所以d1 = driver.get(websites[1])会让d1等于None。直接删除d1=，改为：

driver.get(websites[1])

2. 修复第二个错误：元素不可交互

这个错误是因为元素未加载完成、被遮挡或不在可见区域，需做以下优化：

（1）初始化显式等待对象

替换time.sleep()为Selenium显式等待，确保元素加载完成后再操作，先添加初始化代码：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 10)  # 最多等待10秒

（2）等待元素可交互后再操作

修改下拉框选择的代码，等待元素可点击：

cam_select = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="codCamara"]')))
cam = Select(cam_select)
cam.select_by_value(value)

（3）修复标签页重复创建问题

循环中每次新建标签页会导致window_handles索引失效，查询完成后关闭当前标签页并切回原页面：

# 在每个分支的try/finally块中添加
driver.close()
driver.switch_to.window(driver.window_handles[0])

（4）优化输入框清空逻辑

Keys.CONTROL + "a"仅选中内容，需改为clear()清空输入框：

mat.clear()
mat.send_keys(要输入的内容)
