简单的点击式Javascript下拉导航，无需使用开关/tab

Simple Onclick Javascript Drop Down Navigation without using switch / tab

本文关键字：开关 tab 导航 Javascript 简单      更新时间：2023-09-26

使用Javascript还很新鲜。希望避免使用Jquery或其他框架。

这是一个简单的下拉导航，我正试图使用我在这里找到的脚本创建：http://blog.movalog.com/a/javascript-toggle-visibility/

我需要一些帮助来清理一些代码，并获取一些指针。它按我需要的方式工作，但我想把它缩短一点。谢谢
