Selenium Python-可以找到表（带回行数/列数），但是找不到要单击的特定元素

Question

已经感谢为我提供帮助的用户。我正在导航到网址enfa.co.uk。我将ChromeDriver与Python中的Selenium结合使用，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”，然后单击特定的赛季“ 1950/51”。

这将我带到一个表，该表试图单击“ Res”列下的值。这将带我进入更多数据（我必须登录才能访问此数据，但是无论哪种方式，用户单击此链接都会将其带到也具有所需结果的订阅页面）。

我已经通过计算行数/列数来检查我是否在期望表中，这与我的期望相符（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，应与第7行/第7列相对应），我收到一条回溯消息，指出该元素不可交互。同样，如果我尝试打印此元素，它将显示为空白。有什么想法吗？预先感谢。

match.click()
print('Check:', value)

必需元素的HTML：

跟踪错误：

Answer 1

该元素在可见之前就存在于html中，因此EC.presence_of_element_located为true，但该元素仍处于隐藏状态，无法单击。请改用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，以切换到默认内容，然后再切换到主框架
