你可以替换但不能自定义默认ABP组件的原因是禁用或更改该组件的一部分可能会导致问题. 所以我们把这些组件称为可替换组件.

创建一个你想要使用的新组件,添加到 中的 declarations 和entryComponents 中.

然后打开 app.component.ts 使用 AddReplaceableComponent 将你的组件替换ABP组件. 如下所示:

每个ABP主题模块有3个布局,分别是ApplicationLayoutComponent, AccountLayoutComponent, EmptyLayoutComponent. 这些布局可以用相同的方式替换.

下面的例子解释了如何更换 ApplicationLayoutComponent:

运行以下命令在 angular 文件夹中生成布局:

  1. yarn ng generate component my-application-layout

在你的布局模板(my-application-layout.component.html)中添加以下代码:

  1. <router-outlet></router-outlet>
  1. import { AddReplaceableComponent } from '@abp/ng.core'; // imported AddReplaceableComponent
  2. import { eThemeBasicComponents } from '@abp/ng.theme.basic'; // imported eThemeBasicComponents enum for component keys
  3. import { Store } from '@ngxs/store'; // imported Store
  4. import { MyApplicationLayoutComponent } from './my-application-layout/my-application-layout.component'; // imported MyApplicationLayoutComponent
  6. @Component(/* component metadata */)
  7. export class AppComponent {
  8.   constructor(
  9.     private store: Store, // injected Store
  10.   ) {
  11.     // dispatched the AddReplaceableComponent action
  12.     this.store.dispatch(
  13.       new AddReplaceableComponent({
  14.         component: MyApplicationLayoutComponent,
  15.         key: eThemeBasicComponents.ApplicationLayout,
  16.       }),
  17.     );
  18.   }
  19. }

Layout Components

如何替换LogoComponent

在 angular 目录下运行以下命令创建新的组件 LogoComponent:

  1. yarn ng generate component logo --inlineTemplate --inlineStyle --entryComponent
  3. # You don't need the --entryComponent option in Angular 9

打开 src/app/logo 目录下生成的 logo.component.ts 并使用以下内容替换它:

打开 src/app 目录下的 app.component.ts 做以下修改:

  1. import { ..., AddReplaceableComponent } from '@abp/ng.core'; // imported AddReplaceableComponent
  2. import { Store } from '@ngxs/store'; // imported Store
  3. import { LogoComponent } from './logo/logo.component'; // imported NavItemsComponent
  4. import { eThemeBasicComponents } from '@abp/ng.theme.basic'; // imported eThemeBasicComponents
  5. //...
  7. @Component(/* component metadata */)
  8. export class AppComponent implements OnInit {
  9.   constructor(..., private store: Store) {} // injected Store
  11.   ngOnInit() {
  12.     //...
  14.     // added dispatch
  15.     this.store.dispatch(
  16.       new AddReplaceableComponent({
  17.         component: LogoComponent,
  18.         key: eThemeBasicComponents.Logo,
  19.       }),
  20.     );
  21.   }
  22. }

最终UI如下:

New logo

如何替换RoutesComponent

在 angular 目录下运行以下命令创建新的组件 RoutesComponent:

  1. yarn ng generate component routes --entryComponent
  3. # You don't need the --entryComponent option in Angular 9
  1. import { ABP, ReplaceableComponents } from '@abp/ng.core';
  2. import {
  3.   Component,
  4.   HostBinding,
  5.   Inject,
  6.   Renderer2,
  7.   TrackByFunction,
  8.   AfterViewInit,
  9. } from '@angular/core';
  10. import { fromEvent } from 'rxjs';
  11. import { debounceTime } from 'rxjs/operators';
  13. @Component({
  14.   selector: 'app-routes',
  15.   templateUrl: 'routes.component.html',
  16. })
  17. export class RoutesComponent implements AfterViewInit {
  18.   @HostBinding('class.mx-auto')
  19.   marginAuto = true;
  21.   smallScreen = window.innerWidth < 992;
  23.   constructor(private renderer: Renderer2) {}
  25.   ngAfterViewInit() {
  26.     fromEvent(window, 'resize')
  27.       .pipe(debounceTime(150))
  28.       .subscribe(() => {
  29.         this.smallScreen = window.innerWidth < 992;
  30.       });
  31.   }
  32. }

打开 src/app/routes 目录下生成的 routes.component.html 并使用以下内容替换它:

  1. <ul class="navbar-nav">
  2.   <li class="nav-item">
  3.     <a class="nav-link" routerLink="/"
  4.       ><i class="fas fa-home"></i> {{ '::Menu:Home' | abpLocalization }}</a
