Selenium Python：尝试在 iframe 中获取 iframe

Question

我正在尝试将 Selenium 'focus' 切换到另一个 iframe 内的 iframe 内的内容。到目前为止，我下面的硒测试似乎有效。但是，我想获取该 iframe 中的另一个 iframe - 但我现在不确定。

这是标记（突出显示的第二个 iframe）：

这是我到目前为止的测试（有效 - 只是不确定如何在第一个 iframe 中获取第二个 iframe）：

import unittest
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ec
from .functional_test import FunctionalTest


class MyTest(FunctionalTest):
    URL = '/datastory/my-datastory/'


    @classmethod
    def setUpClass(cls):
        """Set up method."""
        super().setUpClass()

        cls.URL = cls.format_url(cls.URL)
        cls.login_user(cls)

    def test_iframe(self):
        container = self.browser.find_element_by_id('visual-31')
        carousel = container.find_element_by_css_selector('.col-sm-12:nth-child(2) div.visual #classics-50-carousel')
        wait = WebDriverWait(self.browser, 60)
        wait.until(ec.visibility_of(carousel))
        page_source = carousel.get_attribute("src");
        self.assertEqual(
            page_source,
            'https://observablehq.com/embed/@ddsg/paramount-databyte-visuals?cells=classics50yrs'
        )
        # switch Selenium focus to the iframe
        iframe = self.browser.switch_to.frame(carousel);
        #NOW HOW DO I GET THE OTHER IFRAME??
        # switch back
        self.browser.switch_to.default_content()

要在嵌套的 <iframe> 元素内切换，您必须：

为父框架引入WebDriverWait并切换到它.
为 child 引入 WebDriverWait 框架可用并切换到它.
然后driver.find_element()

您可以使用以下任一项:

使用CSS_SELECTOR:

driver.get('https://xyz/datastory/my-datastory/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.content[src='https://observablehq.com/embed/@ddsg/paramount-databyte-visuals?cells=classics50yrs']")))
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.content[src*='observableusercontent']")))
element = driver.find_element(By.ID, "id")

使用 XPATH:

driver.get('https://xyz/datastory/my-datastory/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@class='content' and @src='https://observablehq.com/embed/@ddsg/paramount-databyte-visuals?cells=classics50yrs']")))
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[starts-with(@src, 'observableusercontent')]")))
element = driver.find_element(By.ID, "id")

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
