layui 框架与BootCSS框架相似都属于前端美化框架，区别在于BootCSS更加专业，而LayUI则更多的是面向于后端开发者，所以在组织形式上毅然采用了几年前的以浏览器为宿主的类 AMD 模块管理方式，却又并非受限于 CommonJS 的那些条条框框，它拥有自己的模式，更加轻量和简单。
下面的页面作为基模板，取名为 base.html 后期子模版，全部继承它。

上面的代码a标签如果被填上待跳转路径就会出现，跳转虽然实现了，但是a标签无法高亮，解决的办法这里我想到了一个比较笨的方法。
var Arry = ["/host/","/logs/"];
for(var x=0;x<10;x++)
{
var log = window.location.pathname;
if (Arry[x] == log){
$(".layui-side-scroll li").removeClass("layui-nav-itemed")[0];
$(".layui-side-scroll li").removeClass("layui-this")[0];
$(".layui-side-scroll li").next().eq(x).addClass("layui-this");
$(".layui-side-scroll li").next().eq(x).addClass("layui-nav-itemed");
}
}
最终的效果是这样的。
我们继续完善这个main.html 页面，仪表盘用于统计本机数据。
