循序渐进的方法：

1. 切换到每个 iframe 并检查元素。
2. 通过递归切换和检查来处理嵌套的 iframe。
3. 使用 WebDriverWait 处理元素的动态加载。

示例代码

下面是一个示例函数，演示了如何实现这一点：

from selenium.webdriver.support import expected_conditions as EC

def find_element_in_iframes(driver, locator):
    def recursive_search_in_iframes(driver):
        iframes = driver.find_elements(By.TAG_NAME, 
        iframes = driver.find_elements(By.TAG_NA
"iframe")
        for i, iframe in enumerate(iframes):
            driver.switch_to.frame(iframe)

            driver.switch_to.frame(ifr
try:
                element = WebDriverWait(driver, 
                elemen
2).until(
                    EC.presence_of_element_located(locator)
                )

                    EC.presence_of_element_located(locator)


                    EC.presence_of_eleme


return element
            except:
                pass

    driver.switch_to.window(original_window)
    r

    element = recursive_search_in_iframes(driver)
    driver.switch_to.window(original_window)



    original_window = driver.current_window_handle

    driver.switch_to.window(original_window)

# Example usage
driver = webdriver.Chrome()
driver.get(
driver = webdriver.Chrome()
driver

driver = webdriver.Chrome()
dr

driver = webdriver.Chrome(

driver = webdriver.Chr

driver = webdriver

driver = webdr

driver = w

driver

d
"your_webpage_url")

# Define the locator for the element you are looking for
locator = (By.CSS_SELECTOR, "your_css_selector")

# Find the element within iframes
element = find_element_in_iframes(driver, locator)
if element:
    print("Element found:", element)

    print("Element not found")

driver.quit()

解释

1. 初始化 WebDriver：启动 WebDriver 并导航到所需的 URL。

2. 定义find_element_in_iframes函数

：该函数：

• 定义一个recursive_search_in_iframes辅助函数来处理嵌套的 iframe。
• 在当前页面上搜索 iframe，切换到每个 iframe，并尝试找到所需的元素。
• 如果未找到该元素，它会在嵌套的 iframe 内递归搜索。

• 如果找到则返回该元素，None如果未找到则返回该元素。

• 用法：定义要查找的元素的定位器，并find_element_in_iframes使用驱动程序和定位器调用该函数。

处理动态加载

为了处理动态加载，该函数使用WebDriverWaitwith presence_of_element_located。您可以根据具体要求调整等待时间和条件。

笔记

确保locator要查找的元素的 定义正确。此方法可帮助您在多层 iframe 中搜索元素，而无需手动切换到每一层。
