Selenium Python - 可以定位表（带回没有行/列）但找不到要单击的特定元素

Question

已经感谢帮助我完成这项工作的用户。 我正在导航到 url enfa.co.uk。 我在 Python 中使用 ChromeDriver 和 Selenium 并导航（通过 iframe）从左侧菜单中单击“俱乐部”链接，然后切换 iframe 以选择下拉值“选择俱乐部 = 什鲁斯伯里镇”，然后单击特定的'1950/51' 季。

这会将我带到一个表，我试图单击“Res”列下的值。 这将使我获得更多数据（我必须登录才能访问这些数据，但无论哪种方式，用户点击此链接都会将他们带到订阅页面，该页面也具有所需的结果）。

我已经通过计算行/列数检查我是否在预期的表中，这符合我的期望 (97/9)。 但是，当我尝试单击所需的元素时（在此示例中，Res 为 0-0，应对应于第 7 行/第 7 列），我收到一个回溯，指出该元素不可交互。 同样，如果我尝试打印此元素，它会显示为空白。 有什么想法吗？ 提前致谢。

所需元素的 HTML：

追溯错误：

Answer 1

该元素在可见之前已存在于 html 中，因此EC.presence_of_element_located为 true 但该元素仍处于隐藏状态且无法单击。 改用EC.visibility_of_element_located

match = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "/html/body/form/div[7]/table/tbody/tr[7]/td[7]/a")))

Answer 2

请找到更新的解决方案。 单击元素时需要更改显式等待方法。

我还更新了代码以在切换到主框架之前切换到默认内容
