Question

我知道这不是新错误，但我已经完成了关于此主题的StackExchange和StackOverflow的所有答案，但仍然无法解决StaleElementException。我使用了隐式和显式等待（参见代码注释）。请提供解决方案，也请在回答问题之前访问该网站，这样您就可以准确了解我的目标。我想从dropdown元素中获取所有数据（是的，也尝试了Select类）。这里的问题是StaleElementException。问题不在于下拉，而是StaleElementException我似乎无法摆脱它。请帮助。提前谢谢。

代码：

`PinId = 'ctl00_Contentplaceholder2_ddlPin'
 RoadId = 'ctl00_Contentplaceholder2_ddlRoadName'

            BuildingSelect = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, BuildingId)))
            BuildingSelect.send_keys(b.get_attribute("value"))

            # print(b.text)

 except StaleElementReferenceException:
    print('e')`
