没有检测到视频因而直接显示播放完毕

Bilibili@两束月光的反馈：为啥停在学习日志，过了一会儿就认定这个视频播完了呀

Me：Hello，在程序运行的时候有操控这个页面吗

[LetMeFly666]

Bilibili@两束月光：没有

[LetMeFly666]

Me：感谢反馈，初步分析认为这是一个BUG，原因是你的界面中默认选中的是“学习日志”这一栏目而不是“学习内容”这一栏目，程序只能识别“学习内容”这一栏目的内容而无法识别“学习日志”这一栏目的内容，未识别出课程从而导致程序认为课程已经全部播放完毕。

有空的时候我会修复一下这个BUG，当前一个可行的解决方案(也许)是在进入雨课堂主页后陈其不备点击一下”学习内容“这一栏目，这样的话有一定概率能识别出来未播放内容，但是不能确保播放完一个视频后再次检测剩余未播放完成的视频时（会刷新页面）能否正常识别。

Bilibili@阿铭技高一筹的反馈：

1.原代码126行else部分内容为：
# 点击tab-content标签
tabContent = driver.find_element(By.ID, 'tab-content')
tabContent.click()
iframe = driver.find_elements(By.CLASS_NAME, 'tab-pane-content-iframe')
driver.switch_to.frame(iframe[0]) # 切换到 iframe
allClasses = driver.find_elements(By.CLASS_NAME, 'leaf-detail')
2.原代码153行换为：
return_button = driver.find_element(By.XPATH, '//span[text()="返回"]')
return_button.click()
目前看来可用。

快速点击学习内容现看来不起作用，原因是driver.find_elements(By.CLASS_NAME, 'leaf-detail')代码获取不到allClasses对象，因为allClasses在更新后的代码中被封装到ifame中[藏狐]

[iframe](https://search.bilibili.com/all?from_source=webcommentline_search&keyword=iframe&seid=6995263828998881954) = driver.[find_elements](https://search.bilibili.com/all?from_source=webcommentline_search&keyword=find_elements&seid=6995263828998881954)(By.CLASS_NAME, 'tab-pane-content-iframe')

2.原代码153行换为：
return_button = driver.find_element(By.XPATH, '//span【text()="返回"】')
return_button.click()
目前看来可用。

验证可行，只是需要将【】 更换为 [ ]
