selenium：等待元素可点击不起作用

Question

我正在尝试使用 Expected_conditions.element_to_be_clickable 但它似乎不起作用。在大约 30% 的运行中，我仍然看到“元素...不可点击”错误。

这是完整的错误消息：

selenium.common.exceptions.WebDriverException：消息：未知错误：元素...在点（621、337）处不可单击。其他元素将收到点击：...（会话信息：chrome=60.0.3112.90）（驱动程序信息：chromedriver=2.26.436421（6c1a3ab469ad86fd49c8d97ede4a6b96a49ca5f6），platform=Mac OS X 10.12.6 x86_64）

这是我正在使用的代码：

def wait_for_element_to_be_clickable(selector, timeout=10):
  global driver
  wd_wait = WebDriverWait(driver, timeout)

  wd_wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, selector)),
    'waiting for element to be clickable ' + selector)
  print ('WAITING')
  return driver.find_element_by_css_selector(selector)

更新：

所以现在这真的很奇怪。即使我添加几个固定的等待时间，它仍然偶尔会抛出错误消息。这是进行调用的代码：

  sleep(5)
  elem = utils.wait_for_element_to_be_clickable('button.ant-btn-primary')
  sleep(5)
  elem.click()

最终创建了我自己的自定义函数来处理异常并执行重试：

""" custom clickable wait function that relies on exceptions. """
def custom_wait_clickable_and_click(selector, attempts=5):
  count = 0
  while count < attempts:
    try:
      wait(1)
      # This will throw an exception if it times out, which is what we want.
      # We only want to start trying to click it once we've confirmed that
      # selenium thinks it's visible and clickable.
      elem = wait_for_element_to_be_clickable(selector)
      elem.click()
      return elem

    except WebDriverException as e:
      if ('is not clickable at point' in str(e)):
        print('Retrying clicking on button.')
        count = count + 1
      else:
        raise e

  raise TimeoutException('custom_wait_clickable timed out')
