无法访问 Iframe Python Selenium 中的下拉菜单

Question

感谢您查看我的问题，感谢您的帮助。

我查看了可用的答案，但似乎没有一个对我有用。其他答案似乎涉及切换到 iframe，我成功地做到了（否则它会更快崩溃，对吗？），然后我无法在该 iframe 中选择下拉菜单。

我尝试的一些方法：

Unable to click on dropdown within iframe - Selenium Python

Can't access dropdown select using Selenium in Python

Python Selenium - Cant Click on Button (iFrame Solved !)

由于某种原因，该元素不存在 - 我尝试使用等待语句（sleep 和 EC.waits），但这也不起作用。当我观察程序运行时，可以看到驱动成功加载了 iframe 并且元素是可选择的，所以我认为这可能是您对 iframe 元素的访问方式的误解。

这是代码，您会注意到它位于登录块后面，我不知道在这种情况下我能做些什么来帮助人们达到这一点，但我已经分享了所有我能做到的 html 和代码考虑并可以根据要求分享更多内容：

def clear_wardrobe():
    """Clears the user's wardrobe so that they have no items listed"""
    try:
        # Initialize
        log_in()

        # Fetch the number of items on the page and loop through all of them.
        while True:
            driver.get("https://www.grailed.com/users/myitems")
            time.sleep(2)
            item = driver.find_element_by_xpath("//*[@id=\"wardrobe\"]/div/div[3]/div/div[2]/div[2]/div/div[1]/div[1]/a/div[2]/img")
            item.click()
            time.sleep(3)

            driver.switch_to.window(driver.window_handles[1])

            element = driver.find_element_by_xpath("/html/body/div[8]/div/div[2]/div[3]/div[9]/div[2]/span/a")
            actions = ActionChains(driver)
            actions.move_to_element(element).perform()

            time.sleep(0.5)
            element = driver.find_element_by_xpath("//*[@id=\"Listing--Actions\"]/div/div[1]")
            element.click()
            time.sleep(1)

            # switch to specific iframe and select "Sold Elsewhere option" - ISSUE IS HERE
            frame = driver.find_element_by_xpath("//iframe[contains(@title,'Optimizely Internal Frame')]")
            driver.switch_to.frame(frame)
            select_box = Select(driver.find_element_by_name("reason"))
            select_box.select_by_visible_text("Sold Elsewhere")
            time.sleep(3)
            driver.find_element_by_xpath("//*[@type='submit']").click()

    except NoSuchElementException:
        print("Something went wrong in clearWardrobe()")
        traceback.print_exc()

这是带有下拉菜单的页面 - 我想选择在其他地方出售

这是错误信息：

原来元素是模态的，而不是 iframe，所以这个问题是有缺陷的。
