硒元素找不到

Question

我试着按元素类向下滚动。我需要在twitter.com中滚动推特

from time import sleep

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


driver = webdriver.Firefox()
driver.get('http://twitter.com/elonmusk')
sleep(5)

while True:
    html = driver.find_element_by_class_name('css-901oao r-1fmj7o5 r-1qd0xha r-a023e6 r-16dba41 r-rjixqe r-bcqeeo r-bnwqim r-qvutc0')
    html.send_keys(Keys.END)

我有错误：

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: .css-901oao r-1fmj7o5 r-1qd0xha r-a023e6 r-16dba41 r-rjixqe r-bcqeeo r-bnwqim r-qvutc0

Answer 1

该类名在代码中有空格，class_name不使用空格，请尝试下面的xpath：

//div[@data-testid='tweet']

你可以用代码写成这样：

counter = 1
while True:
    html = driver.find_element_by_xpath(f"(//div[@data-testid='tweet'])[{counter}]")
    counter =  counter  + 1
    html.send_keys(Keys.END)
