Javascript 悬停时更改进度条跨距文本
我有两个正在折叠的选项卡，每个选项卡上显示5个进度条。我希望当用户将鼠标悬停在进度条上时，进度条百分比（例如“79%”）更改为显示等级（例如“B+”）。我怎样才能做到这一点 第二个问题：我想让每个选项卡折叠另一个选项卡，例如，当我选择“第1学期”时，我想隐藏“第2学期”，反之亦然。如果我关闭“第1学期”，我想让“第2学期”显示等等 代码Javascript 悬停时更改进度条跨距文本,javascript,jquery,html,css,Javascript,Jquery,Html,Css,我有两个正在折叠的选项卡，每个选项卡上显示5个进度条。我希望当用户将鼠标悬停在进度条上时，进度条百分比（例如“79%”）更改为显示等级（例如“B+”）。我怎样才能做到这一点 第二个问题：我想让每个选项卡折叠另一个选项卡，例如，当我选择“第1学期”时，我想隐藏“第2学期”，反之亦然。如果我关闭“第1学期”，我想让“第2学期”显示等等 代码 在进度条中添加两个元素，一个表示百分比，一个表示等级。然后默认情况下隐藏一个。然后根据父悬停切换可见性 .progress.progress bar>spa
