Python Selenium单击没有ID的按钮

Question

我有此代码

"Answer1","Answer2"

我该怎么办？页面上还有其他具有相同类的按钮，等等，唯一的变量是

import pickle

a = [1,2,3]
b = [4,5,6]
with open("pickle1.dat", 'wb') as f:
    pickle.dump(a, f)
    pickle.dump(b, f)

c = None
d = None
with open("pickle1.dat", 'rb') as f:
    c = pickle.load(f)
    d = pickle.load(f)

print(c)
print(d)

Answer 1

要单击带有投票的文本的链接，可以使用以下任一解决方案：

• css_selector：

  driver.find_element_by_css_selector("a.button.expanded.vote[onclick*='Answer1'][onclick*='Answer2']").click()
  

• xpath：

  driver.find_element_by_xpath("//a[@class='button expanded vote' and contains(.,'Vote')][contains(@onclick,'Answer1') and contains(@onclick,'Answer2')]").click()
  

---

更新

诱导 WebDriverWait 以使所需的元素可点击，如下所示：

• css_selector：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.button.expanded.vote[onclick*='Answer1'][onclick*='Answer2']"))).click()
  

• xpath：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='button expanded vote' and contains(.,'Vote')][contains(@onclick,'Answer1') and contains(@onclick,'Answer2')]"))).click()
  

注意：您必须添加以下导入：

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