  7. // @node         功能1：拦截了登陆界面的弹窗,将错误提示显示在页面上,而不是弹窗
  8. // @node         功能2：选体育课页面中，添加了抢课按钮，位于普通选择按钮的右侧，点击即可进行抢课。
  9. // @node         功能3：选修课页面中，添加了抢课面板，可以进行跨页选择,在想要抢的课的最后一栏点击按钮“添加到抢课”即可添加到面板 而后可以点击提交
  10. // @node         目前webkit内核的浏览器使用此脚本时会出现一些bug,暂未解决
  11. // @node         选修课面板的判断需要做处理,等到抢课的时候即可进行改正。
