1-我希望右侧边栏采用相同的视频高度
2-当我更改视频时它不会达到相同的高度，请点击第2章查看问题
仅在我调整页面大小时才开始工作
我不知道为什么侧边栏没有采取相同的视频高度，任何人都可以帮助我吗？

这是因为您需要对点击事件应用更改。因此，您可以添加此代码以在每次单击章节时调整视频大小（您可能会添加一些延迟以确保获得正确的大小）：
$('ul.nav-tabs a').click(function() {
setTimeout(function() {
var vidHeight = $('.video-container').height();
$('.description').css('height', vidHeight + 'px');
}, 500);
});
您也可以使用$(document).ready函数，以确保调整大小代码在页面加载时运行良好。
完整代码：
$(document).ready(function() {
setTimeout(function() {
var vidHeight = $('.video-container').height();
$('.description').css('height', vidHeight + 'px');
}, 500);
$(window).resize(function() {
var vidHeight = $('.video-container').height();
$('.description').css('height', vidHeight + 'px');
});
$('ul.nav-tabs a').click(function() {
setTimeout(function() {
var vidHeight = $('.video-container').height();
$('.description').css('height', vidHeight + 'px');
}, 500);
});
