<iframe name="Dialogue Window">

回答by budi

You can use an XPath to locate the <iframe>:

您可以使用 XPath 来定位<iframe>：

iframe = driver.find_element_by_xpath("//iframe[@name='Dialogue Window']")

Then switch_tothe <iframe>:

然后switch_to在<iframe>：

driver.switch_to.frame(iframe)

Here's how to switch back to the default content (out of the <iframe>):

以下是切换回默认内容（在 之外<iframe>）的方法：

driver.switch_to.default_content()

As per the HTML of the <iframe>element, it has the nameattribute set as Dialogue Window. So to switch within the <iframe>you need to use the switch_to()method and you can use either of the following approaches:

根据<iframe>元素的 HTML ，它的name属性设置为Dialogue Window。因此，要在<iframe>您需要使用该switch_to()方法的范围内切换，您可以使用以下任一方法：

• Using the nameattribute of the <iframe>node as follows:

  # driver.switch_to.frame(‘frame_name')
  driver.switch_to.frame("Dialogue Window")
  

• Using the <iframe>WebElementidentified through nameattribute as follows:

  driver.switch_to.frame(driver.find_element_by_name('Dialogue Window'))
  

• Using the <iframe>WebElementidentified through css-selectorsas follows:

  driver.switch_to.frame(driver.find_element_by_css_selector("iframe[name='Dialogue Window']"))
  

• Using the <iframe>WebElementidentified through xpathas follows:

  driver.switch_to.frame(driver.find_element_by_css_selector("//iframe[@name='Dialogue Window']"))
  

• Ideally, you should induce WebDriverWaitinconjunction with expected_conditionsas frame_to_be_available_and_switch_to_it()for the desired frameas follows:

  • Using NAME:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,"Dialogue Window"))) 
    

  • Using CSS_SELECTOR:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name='Dialogue Window']")))
    

  • Using XPATH:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@name='Dialogue Window']")))
    

• To switch back to the Parent Frameyou can use the following line of code:

  driver.switch_to.parent_frame()
  

• To switch back to the Top Level Browsing Context/ Top Windowyou can use the following line of code:

  driver.switch_to.default_content()
  

• 使用节点的name属性<iframe>如下：

  # driver.switch_to.frame(‘frame_name')
  driver.switch_to.frame("Dialogue Window")
  

• 使用通过name属性标识的<iframe>WebElement如下：

  driver.switch_to.frame(driver.find_element_by_name('Dialogue Window'))
  

• 使用通过css-selectors标识的<iframe>WebElement如下：

  driver.switch_to.frame(driver.find_element_by_css_selector("iframe[name='Dialogue Window']"))
  

• 使用通过xpath标识的<iframe>WebElement如下：

  driver.switch_to.frame(driver.find_element_by_css_selector("//iframe[@name='Dialogue Window']"))
  

• 理想情况下，应当诱导WebDriverWaitinconjunction与expected_conditions作为frame_to_be_available_and_switch_to_it()用于期望帧如下：

  • 使用NAME：

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,"Dialogue Window"))) 
    

  • 使用CSS_SELECTOR：

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name='Dialogue Window']")))
    

  • 使用XPATH：

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@name='Dialogue Window']")))
    

• 要切换回父框架，您可以使用以下代码行：

  driver.switch_to.parent_frame()
  

• 要切换回顶级浏览上下文/顶级窗口，您可以使用以下代码行：

  driver.switch_to.default_content()
