最近组件库更新比较频繁,有些同学感觉有点迷茫,就着今天刚上了张老板一节课立马撸个新的上手教程回馈社区, ;->

1.新建工程b18QuickStartv757,将项目添加到解决方案中

dotnet new blazorserver -o b18QuickStartv757 dotnet sln add b18QuickStartv757/b18QuickStartv757.csproj 

2.使用 nuget.org 进行 BootstrapBlazor 组件安装, FreeSql sqlite库,字体 ..

dotnet add b18QuickStartv757 package BootstrapBlazor dotnet add b18QuickStartv757 package BootstrapBlazor.FontAwesome 

2.样式表和Javascript 引用

增加主题样式表到 Pages/_Host.cshtml 文件中

删除 <link rel="stylesheet" href="css/bootstrap/bootstrap.min.css" />

并在下面添加两行

<link href="_content/BootstrapBlazor.FontAwesome/css/font-awesome.min.css" rel="stylesheet"> <link href="_content/BootstrapBlazor/css/bootstrap.blazor.bundle.min.css" rel="stylesheet"> 

添加 Javascript 引用到 Pages/_Host.cshtml 文件中

<script src="_framework/blazor.server.js"></script> 之前添加

<script src="_content/BootstrapBlazor/js/bootstrap.blazor.bundle.min.js" asp-append-version="true"></script> 

3.添加增加命名空间引用到 _Imports.razor 文件中

@using BootstrapBlazor.Components 

4.增加 BootstrapBlazorRoot 组件到 App.razor 文件中

<BootstrapBlazorRoot>     <Router AppAssembly="@typeof(App).Assembly">         ...     </Router> </BootstrapBlazorRoot> 

5.添加BootstrapBlazor服务到 Program.cs 文件中

builder.Services.AddSingleton<WeatherForecastService>(); 后加入

builder.Services.AddBootstrapBlazor(); 

以下步骤纯属个人喜好 , 改造原版 NavMenu 组件

6. 新建 menu.js 文件

wwwroot 建立 modules文件夹, 新建 menu.js 文件

import Data from "../_content/BootstrapBlazor/modules/data.js"; import EventHandler from "../_content/BootstrapBlazor/modules/event-handler.js";  export function init(id) {     var el = document.getElementById(id)     if (el === null) {         return     }     const navbar = el.querySelector('.navbar-toggler')     const menu = el.querySelector('.sidebar-content')     const nav = { navbar, menu }     Data.set(id, nav)      EventHandler.on(navbar, 'click', () => {         menu.classList.toggle('show')     })     EventHandler.on(menu, 'click', '.nav-link', e => {         const link = e.delegateTarget         const url = link.getAttribute('href');         if (url !== '#') {             menu.classList.remove('show')         }     }) }  export function dispose(id) {     const nav = Data.get(id)     if (nav) {         EventHandler.off(nav.navbar, 'click');         EventHandler.off(nav.menu, 'click', '.nav-link');     } } 

7. 替换 SharedNavMenu.razor 文件

@inherits BootstrapModuleComponentBase @attribute [JSModuleAutoLoader("./modules/menu.js", Relative = false)]  <div id="@Id">     <div class="navbar d-flex d-md-none px-3">         <a class="navbar-brand" href="">Demo</a>         <button class="navbar-toggler" aria-label="toggle">             <span class="navbar-toggler-icon"></span>         </button>     </div>      <div class="sidebar-content collapse d-md-block">         <div class="scroll">             <Menu Items="@Menus" IsVertical="true" IsAccordion="true" IsExpandAll="true" />         </div>     </div> </div> 

8. 新建 SharedNavMenu.razor.cs 文件

using BootstrapBlazor.Components; using Microsoft.AspNetCore.Components.Routing;  namespace b18QuickStartv757.Shared;  public partial class NavMenu {     private IEnumerable<MenuItem> Menus { get; set; } = new List<MenuItem>     {             new MenuItem() { Text = "首页", Url = "/"  , Match = NavLinkMatch.All},             new MenuItem() { Text = "Counter", Url = "/counter" },             new MenuItem() { Text = "Fetch data", Url = "/fetchdata" },             new MenuItem() { Text = "工具" ,Items= new List<MenuItem>                 {                     new MenuItem() { Text = "Counter", Url = "/counter" },                     new MenuItem() { Text = "Fetch data", Url = "/fetchdata" },                }             },     }; } 

9. 替换 SharedMainLayout.razor 文件

@inherits LayoutComponentBase @using System.Reflection  <section class="section">     <div class="sidebar">         <div class="sidebar-title">             <span class="sidebar-text">DEMO</span>         </div>         <NavMenu />     </div>     <div class="main">         <div class="content px-3">             <Tab ClickTabToNavigation="true"                  ShowExtendButtons="true"                  ShowClose="true"                  Body=@Body />         </div>     </div> </section> 

10. 替换 SharedMainLayout.razor.css 文件

 .layout-main .main {     background: rgba(16, 142, 233, 1);     color: #fff;     min-height: 120px;     width: 100%;     height: 100%;     display: flex;     align-items: center;     justify-content: center;     flex-flow: column; }  .main {     flex: 1; }  .sidebar .navbar-brand {     font-size: 1.1rem; }  .sidebar .nav-item {     font-size: 0.875rem;     padding-left: 6px; }      .sidebar .nav-item a {         color: #444;         border-radius: var(--bs-border-radius);         display: flex;         align-items: center;         padding: .25rem 1.5rem;         font-weight: 400;     }  .sidebar .navbar {     --bb-bg-navbar: #8548ff;     background-color: var(--bb-bg-navbar); }  .sidebar .sidebar-title {     display: none; }  .sidebar-text {     font-weight: 700; }  .menu .nav-link.nav-table {     color: var(--bs-info);     font-weight: bold; }      .menu .nav-link.nav-table:hover {         color: unset;     }  @media (max-width: 767.98px) {     .main .top-row:not(.auth) {         display: none;     }      .main .top-row.auth {         justify-content: space-between;     }      .main .top-row a, .main .top-row .btn-link {         margin-left: 0;     } }  @media (min-width: 768px) {     .section {         flex-direction: row;         display: flex;     }      .sidebar {         width: var(--bs-sidebar-width);         height: calc(100vh);         position: sticky;         top: 0;         border-right: solid 1px #c0c4cc;         background-color: #f0f0f0;         display: flex;         flex-direction: column;         margin-top: calc(var(--bs-header-height)*-1);     }          .sidebar .sidebar-content {             height: calc(100vh - var(--bs-header-height));         }              .sidebar .sidebar-content.collapse {                 display: flex;                 flex-direction: column;             }          .sidebar .sidebar-title {             height: 50px;             display: flex;             align-items: center;             padding: 1rem;             border-bottom: solid 1px #c0c4cc;         }          .sidebar .scroll {             overflow-x: hidden;             max-height: calc(100% - 36px);             padding: 5px 0;         }              .sidebar .scroll .menu {                 width: var(--bs-sidebar-width);             } } 

11. Index.razor 在@page下一行添加 attribute

@attribute [TabItemOption(Text = "Index")]
