我正在编写一个与Autotask.net网站交互的脚本。我正打开一个新窗口。我试图用我有限的知识来切换框架并切换窗口，但我已经收到了以下例外情况：
StaleElementReferenceException：消息：元素属于与当前帧不同的帧 - 切换到其包含的帧以使用它
这是我的代码：
# Below code WORKS as is.
browser.switch_to_frame('PageContainerFrame')
browser.find_element_by_xpath('//a[contains(., "T20160101.0100")]').click()
#TESTING
browser.switch_to_default_content()
browser.switch_to_window(browser.window_handles[-1])
title=browser.title
newNote=browser.find_element_by_css_selector('#btnNewNote')
actions.click(newNote)
actions.perform()
非常感谢任何帮助 - 谢谢。
