继续上一篇,针对Bootstrap Metronic菜单栏整理的笔记分享给大家,供大家参考,具体内容如下
1.简介
1) .环境配置
2) .提取页面
3).动态生成菜单(无限级别树)
2.系统环境配置
项目需要程序数据支撑,这里选择MVC5.0+EF6.0[SQLSERVER](不对MVC架构和SQLServer做出解读)
运行环境:VS2013+MVC5.0+EF6.1+SQLServer2012
解决方案名称:AppSolution 项目名称:App.Web(UI层)与App.Models(数据访问层) -直接访问模式
提取theme下的所有文件到MVC的Content,提取admin的index.html到_Layout.cshtml来准备改造
3.创建数据库和表
数据库:AppDataBase
创建以下数据表,并创建AppDB.edmx
USE [AppDataBase] GO /****** Object: Table [dbo].[SysModule] Script Date: 2015/9/15 21:03:39 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[SysModule]( [ID] [varchar](50) NOT NULL, --主键ID [Name] [varchar](50) NOT NULL, --菜单名称 [ParentID] [varchar](50) NULL, --上级ID [Url] [varchar](200) NULL, --URL [Iconic] [varchar](200) NULL, --图标 [Sort] [int] NULL, --排序 [Enable] [bit] NOT NULL, --是否显示 [CreateTime] [datetime] NULL, --创建时间 [IsLast] [bit] NOT NULL --是否最后一项 CONSTRAINT [PK_SysModule] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO SET ANSI_PADDING OFF GO ALTER TABLE [dbo].[SysModule] WITH NOCHECK ADD CONSTRAINT [FK_SysModule_SysModule] FOREIGN KEY([ParentID]) REFERENCES [dbo].[SysModule] ([Id]) GO ALTER TABLE [dbo].[SysModule] NOCHECK CONSTRAINT [FK_SysModule_SysModule] GO
人为造点数据
INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('0','root','root','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('1','一级菜单01','0','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('11','二级菜单01-01','1','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('111','三级菜单01-01-01','11','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('112','三级菜单01-01-02','11','Index','icon-settings',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('12','二级菜单01-02','1','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('13','二级菜单01-03','1','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('2','一级菜单02','0','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('21','二级菜单02-01','2','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('211','三级菜单02-01-01','5','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('212','三级菜单02-01-02','5','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('22','二级菜单02-02','2','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('23','二级菜单02-03','2','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('3','一级菜单03','0','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('31','二级菜单03-01','3','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('311','三级菜单03-01-01','31','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('312','三级菜单03-01-02','31','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('32','二级菜单03-02','3','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('33','二级菜单03-03','3','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('4','一级菜单04','0','Index','icon-settings',NULL,0,NULL,0) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('41','二级菜单04-01','4','Index','icon-link',NULL,0,NULL,1) INSERT INTO [SysModule] ([ID],[Name],[ParentID],[Url],[Iconic],[Sort],[Enable],[CreateTime],[IsLast]) values ('42','二级菜单04-02','4','Index','icon-link',NULL,0,NULL,1) (22 行受影响)
4.提取页面重要布局
我们是后台系统所以我们保留top. left menu和foot3个部分
我已经提取好了,请复制

再次提取菜单代码
<li class="start active open"> <a href="javascript:;"> <i class="icon-folder"></i> <span class="title">Multi Level Menu</span> <span class="arrow "></span> </a> <ul class="sub-menu"> <li> <a href="javascript:;"> <i class="icon-settings"></i> Item 1 <span class="arrow"></span> </a> <ul class="sub-menu"> <li> <a href="javascript:;"> <i class="icon-user"></i> Sample Link 1 <span class="arrow"></span> </a> <ul class="sub-menu"> <li> <a href="#"><i class="icon-power"></i> Sample Link 1</a> </li> <li> <a href="#"><i class="icon-paper-plane"></i> Sample Link 1</a> </li> <li> <a href="#"><i class="icon-star"></i> Sample Link 1</a> </li> </ul> </li> <li> <a href="#"><i class="icon-camera"></i> Sample Link 1</a> </li> <li> <a href="#"><i class="icon-link"></i> Sample Link 2</a> </li> <li> <a href="#"><i class="icon-pointer"></i> Sample Link 3</a> </li> </ul> </li> <li> <a href="javascript:;"> <i class="icon-globe"></i> Item 2 <span class="arrow"></span> </a> <ul class="sub-menu"> <li> <a href="#"><i class="icon-tag"></i> Sample Link 1</a> </li> <li> <a href="#"><i class="icon-pencil"></i> Sample Link 1</a> </li> <li> <a href="#"><i class="icon-graph"></i> Sample Link 1</a> </li> </ul> </li> <li> <a href="#"> <i class="icon-bar-chart"></i> Item 3 </a> </li> </ul> </li>
大约在466行-529行
分析上面html可以看出,li包含ul循环调用。所以我们用递归读取菜单
5.拼接菜单栏
创建Home视图Index.cshtml并应用_Layout.cshtml
Bootstrap Metronic并菜单没有提供Ajax模式,我们只能读取数据拼接HTML
过程:读取数据表数据递归调用using App.Models; using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Text; namespace App.Web.Controllers { public class HomeController : Controller { AppDBContainer db = new AppDBContainer(); public ActionResult Index() { IQueryable<SysModule> menus = db.SysModule.AsQueryable().Where(a=>a.ParentID=="0"); StringBuilder sb = new StringBuilder(); bool firstFlag = true;//第一个默认展开 GetChildMenus(ref sb, menus, firstFlag);//二级菜单 ViewBag.Menus = sb.ToString(); return View(); } //递归调用 public void GetChildMenus(ref StringBuilder sb, IQueryable<SysModule> menus,bool firstFlag)//二级以上菜单 { int count = 0; if(!firstFlag) sb.Append("<ul class='sub-menu'>"); foreach (var m in menus) { IQueryable<SysModule> menusChild = db.SysModule.AsQueryable().Where(a => a.ParentID == m.ID); count = menusChild.Count(); sb.AppendFormat("<li class='{0}'>",firstFlag"start actove open":""); sb.AppendFormat("<a href='{0}'><i class='{1}'></i><span class='title'>{2}</span>{3}</a>", count > 0 "javascript:;" : m.Url, m.Iconic, m.Name, count > 0 "<span class='arrow '></span>" : ""); firstFlag = false; if (count > 0) GetChildMenus(ref sb, menusChild,firstFlag); sb.Append("</li>"); } if (!firstFlag) sb.Append("</ul>"); } } }去掉提取的li替换成@Html.Raw(ViewBag.Menus)
6.总结
前端这种东西最考验人的耐心,不信你自己拼接一下

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
