Python 单击没有id的按钮

我有这个密码

<a href="#" class="button expanded vote" style="background: rgb(51, 204, 102) none repeat scroll 0% 0%; border-radius: 5px;" onclick="Poll.sendAnswer("Programn2015","Answer1","Answer2")">Vote</a>

要单击文本为“投票”的链接，可以使用以下任一解决方案：

• css\u选择器

  ：

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

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((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()
  

  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()

更新 诱导WebDriverWait使所需元素可单击，如下所示：

• css\u选择器

  ：

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

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((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()
  

  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
