python - 如何通过类名找到 btn？

Question

我有这个html代码: <button class="_2ic5v"><span aria-label="Like" class="glyphsSpriteComment_like u-__7"></span></button>

我试图通过 phyton 和 selenium webdriver 库找到满足此类的所有元素: likeBtn = driver.find_elements_by_class_name('_2ic5v')

但是当我打印时 likeBtn 它打印 []

我想找到与此 div/span 类或 aria-label 相关的所有按钮

我怎样才能成功做到这一点？提前致谢

更新 - 当我从页面复制 Xpath 时，打印保持不变

Answer 1

尝试以下 Xpath 选项这将找到包含 aria-label='Like' 的按钮。

//button[./span[@aria-label='Like' and starts-with(@class,'glyphsSpriteComment_like')]]

代码:

likeBtn=driver.find_elements_by_xpath("//button[./span[@aria-label='Like' and starts-with(@class,'glyphsSpriteComment_like')]]")
for button in likeBtn:
    button.click()

已编辑:

引发WebDriverWait。

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

likeBtn=WebDriverWait(driver,20).until(EC.presence_of_all_elements_located((By.XPATH,"//button[./span[@aria-label='Like' and starts-with(@class,'glyphsSpriteComment_like')]]")))
