关于selenium定位元素的问题
我试着运行下面的代码：from selenium import webdriverfrom selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import StaleElementReferenceException
import time
def login_fx(username,password):
...... # 此处是用登录bilbili的代码，最终返回一个已经登录的浏览器（B站首页）
def comment_fx():
browser.get(F"ht请tps:/把/sp我ace.bil去ibili.co掉m/119/dyn！amic") # 访问个人空间
actions2 = ActionChains(browser) # 重新实例化ActionChains对象
time.sleep(1)
browser.find_element_by_class_name("comment").click() # 点击以展开评论区
time.sleep(3)
browser.find_element_by_class_name("ipt-txt").send_keys("123") # 查找评论框
"""
username = str(input("用户名："))
password = str(input("密码："))
"""
login_fx(username,password)
comment_fx()
报错如下：
Traceback (most recent call last):
File "E:\002.py", line 55, in <module>
comment_fx()
File "E:\002.py", line 41, in comment_fx

return self.execute(Command.FIND_ELEMENT, {

raise exception_class(message, screen, stacktrace)

(Session info: chrome=91.0.4472.114)
XPath表达式和class属性均无法使用，我该怎么办？ browser.find_element_by_class_name("comment").click() # 点击以展开评论区
改成
btn = browser.find_element_by_class_name("comment")
browser.execute_script("arguments.click()",btn)
就好了 向下方滚动也无法加载
