一、效果展示
1、div实现效果
2、iframe实现效果
二、左侧菜单栏样式
菜鸟左侧菜单栏中有5个示例，基本满足了大部分场景需求。
参考文档：Bootstrap5 侧边栏导航(Offcanvas) | 菜鸟教程
我这里采用的是第4个样式，这个样式只展示了左侧菜单栏。
接下来我将实现左侧菜单栏和右侧主界面的联动跳转。
三、菜单栏和右侧主界面的联动跳转
有2中比较常用的实现方式：
1、使用div实现主界面切换
实现思路
- 动态监听 a 的 click事件；
- 取消默认click事件（跳转到一个新的窗口，而不是当前页面的div中）；
- 将 a的 href 链接地址load到div元素上
关键代码
主页面div元素：
<div id="main"></div>div的js跳转代码：
$(document).ready(function () {
$("#main").load('tab1.html');
$("a").click(function (e) {
e.preventDefault();
// $(this).tab('show');
$("#main").load($(this).attr("href"));
})
})2、使用iframe实现主界面切换，src指定对应的*.html文件。
实现思路
- 动态监听 a 的 click事件；
- 取消默认click事件（跳转到一个新的窗口，而不是当前页面的div中）；
- 修改iframe的src属性为click元素的href值；
关键代码
主页面iframe元素：
<iframe id="navFrame" width="100%" height="auto" scrolling="no" frameborder="10" src="tab1.html"></iframe>iframe的js跳转代码：
<script>
$(document).ready(function () {
$("a").click(function (e) {
if ($(this).attr("href").length) {
e.preventDefault();
$(this).tab('show');
$("#navFrame").attr("src", $(this).attr("href"));
}
})
});
</script>四、一页完整代码
