项目场景:
组件:Bootstrap-4.6.2、JQuery 3.7.1
测试浏览器:Firefox126.0.1、Microsoft Edge125.0.2535.67
IDE:eclipes2024-03.R
在编写CRM的工作台主页面时,由于该页面使用的是较旧的技术,所以打算使用Bootstrap重写响应式页面,主要使用了Bootstrap的格栅布局系统。在编写左侧纵向导航栏时,发现添加滚动条后,导航栏下面缩短了一部分流出大部分空白,使得页面不美观。
代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link href="/crm-core/css/bootstrap_css/bootstrap.min.css" type="text/css" rel="stylesheet" />
<script type="text/javascript" src="/crm-core/js/jquery/jquery-3.7.1-min.js"></script>
<!-- bootstrap.bundle.js包含了popper.min.js,这个是下拉菜单的依赖 -->
<script type="text/javascript" src="/crm-core/js/bootstrap_js/bootstrap.bundle.js"></script>
<script type="text/javascript">...
</script>
</head>
<body>...<!-- 中间部分 --><div id="center" style="position: absolute; top: 50px; bottom: 30px; left: 0px; right: 0px;"><!-- 导航 --><div class="col-2 border-right navbar-nav-scroll" style="height: 100%;"><div class="nav flex-column nav-pills" id="v-pills-tab" role="tablist" aria-orientation="vertical"><button class="nav-link active" id="v-pills-home-tab" data-toggle="pill" data-target="#v-pills-home" type="button"role="tab" aria-controls="v-pills-home" aria-selected="true">工作台</button></div></div><!-- 右侧框架栏 --><div class="col-10 iframe-container"><div class="embed-responsive embed-responsive-16by9"><iframe class="embed-responsive-item border border-white" name="workareaFrame"></iframe></div></div></div></div>
</body>
</html>
问题描述
经过测试后,发现是在添加了navbar-nav-scroll后出现截断问题,但是该类如果删除会导致在滚动页面时右侧的<iframe>也会跟着滚动,这不是我所期望的,我想要的只是左侧的导航栏在溢出时滚动,而右侧的<iframe>框架只是用来显示左侧各导航栏对应的页面。
原因分析:
尝试了诸多方法,官方文档也没有给出相关问题的解决方案,AI也没有给出准确的解决方案,在问了别人说的可能是Flex 布局下居中溢出滚动截断问题,看了这边文章 ,不过没看太懂,只是知道不应该用Flex布局。
解决方案:
去除Flex相关代码,以显示的方式指定div的高度,及overflow-y:scroll。

当前的解决方案在一定程度上牺牲了响应式的布局,后期如果有更好的解决方案再更新。
