-# Component Replacement
+## 替换组件
 
-TODO...
\ No newline at end of file
+你可以将一些ABP的组件替换为你自己的自定义组件.
+
+您可以**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.
+
+### 如何替换组件
+
+创建一个你想要使用的新组件,添加到 `AppModule` 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:
+
+```js
+import { ..., AddReplaceableComponent } from '@abp/ng.core'; // imported AddReplaceableComponent action
+import { eIdentityComponents } from '@abp/ng.identity'; // imported eIdentityComponents enum
+import { Store } from '@ngxs/store'; // imported Store
+//...
+export class AppComponent {
+  constructor(..., private store: Store) {} // injected Store
+
+  ngOnInit() {
+    this.store.dispatch(
+      new AddReplaceableComponent({
+        component: YourNewRoleComponent,
+        key: eIdentityComponents.Roles,
+      }),
+    );
+    //...
+  }
+}
+```
+
+![Example Usage](./images/component-replacement.gif)
+
+### 如何替换布局
+
+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.
+
+> 一个布局组件模板应该包含 `<router-outlet></router-outlet>` 元素.
+
+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:
+
+```bash
+yarn ng generate component shared/my-application-layout --export --entryComponent
+
+# You don't need the --entryComponent option in Angular 9
+```
+
+在你的布局模板(`my-layout.component.html`)中添加以下代码:
+
+```html
+<router-outlet></router-outlet>
+```
+
+打开 `app.component.ts` 添加以下内容:
+
+```js
+import { ..., AddReplaceableComponent } from '@abp/ng.core'; // imported AddReplaceableComponent
+import { eThemeBasicComponents } from '@abp/ng.theme.basic'; // imported eThemeBasicComponents enum for component keys
+import { MyApplicationLayoutComponent } from './shared/my-application-layout/my-application-layout.component'; // imported MyApplicationLayoutComponent
+import { Store } from '@ngxs/store'; // imported Store
+//...
+export class AppComponent {
+  constructor(..., private store: Store) {} // injected Store
+
+  ngOnInit() {
+    // added below content
+    this.store.dispatch(
+      new AddReplaceableComponent({
+        component: MyApplicationLayoutComponent,
+        key: eThemeBasicComponents.ApplicationLayout,
+      }),
+    );
+
+    //...
+  }
+}
+```

+# 自定义设置页面
+
+不同的模块提供它们的设置选项卡. 你可以通过3个步骤在项目中自定义设置页面.
+
+1. 创建一个组件
+
+```js
+import { Select } from '@ngxs/store';
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'app-your-custom-settings',
+  template: `
+    custom-settings works! 
+  `,
+})
+export class YourCustomSettingsComponent {
+  // Your component logic
+}
+```
+
+2. 添加 `YourCustomSettingsComponent` 到 `AppModule` 中的 `declarations`和 `entryComponents` 数组中.
+
+3. 打开 `app.component.ts` 在 `ngOnInit` 添加以下内容:
+
+```js
+import { addSettingTab } from '@abp/ng.theme.shared';
+// ...
+
+ngOnInit() {
+  addSettingTab({
+    component: YourCustomSettingsComponent,
+    name: 'Type here the setting tab title (you can type a localization key, e.g: AbpAccount::Login',
+    order: 4,
+    requiredPolicy: 'type here a policy key'
+  });
+}
+```
+
+导航到 `/setting-management` 路由你会看到以下变化:

+# 轻松实现TrackByFunction
+
+`TrackByService` 是一个实用服务,为Angular模板中最常见的需求之一: `TrackByFunction` 提供简单的实现. 在继续下面的内容之前,请参先阅 [Angular 文档](https://angular.io/guide/template-syntax#ngfor-with-trackby).
+
+## 入门
+
+你不必在模块或组件级别提供 `TrackByService`,因为它已经在**根中提供了**. 你可以在组件中注入并开始使用它. 为了获得更好的类型支持,你可以将迭代项目的类型传递给它.
+
+```js
+import { TrackByService } from '@abp/ng.core';
+
+@Component({
+  /* class metadata here */
+})
+class DemoComponent {
+  list: Item[];
+
+  constructor(public readonly track: TrackByService<Item>) {}
+}
+```
+
+> 注意到 `track` 是 `public` 并且 `readonly` 了吗? 因为我们将看到一些在组件模板中直接使用 `TrackByService` 实例的方法示例. 可以把它看做反模式,但它有自身的优势,尤其是在利用组件继承时. 你始终可以使用公共组件属性.
+
+**成员也被导出做为独立的函数.** 如果你不想注入 `TrackByService`, 你可以直接在类中导入并使用这些函数.
+
+## 用法
+
+有两种方法可用.
+
+1. 你可以直接注入 `TrackByService` 到你的组件并且使用它的成员.
+2. 你可以在直接在组件属性上使用导出的函数.
+
+### 如何通过一个键跟踪项
+
+你可以使用 `by` 获取一个 `TrackByFunction` , 该函数根据它的一个键来跟踪迭代的对象. 你可以将迭代类型传递给它获得类型支持.
+
+```html
+<!-- template of DemoComponent -->
+
+<div *ngFor="let item of list; trackBy: track.by('id')">{%{{{ item.name }}}%}</div>
+```
+
+`by` 作为一个独立函数导出,命名为 `trackBy`.
+
+```js
+import { trackBy } from "@abp/ng.core";
+
+@Component({
+  template: `
+    <div
+      *ngFor="let item of list; trackBy: trackById"
+    >
+      {%{{{ item.name }}}%}
+    </div>
+  `,
+})
+class DemoComponent {
+  list: Item[];
+
+  trackById = trackBy<Item>('id');
+}
+```
+
+### 如何通过深度嵌套的键进行跟踪
+
+你可以使用 `byDeep` 获取一个 `TrackByFunction` , 它根据深度嵌套的键跟踪迭代对象. 你可以将迭代类型传递给它获得类型支持.
+
+
+```html
+<!-- template of DemoComponent -->
+
+<div
+  *ngFor="let item of list; trackBy: track.byDeep('tenant', 'account', 'id')"
+>
+  {%{{{ item.tenant.name }}}%}
+</div>
+```
+
+`byDeep` 作为一个独立函数导出,命名为 `trackByDeep`.
+
+```js
+import { trackByDeep } from "@abp/ng.core";
+
+@Component({
+  template: `
+    <div
+      *ngFor="let item of list; trackBy: trackByTenantAccountId"
+    >
+      {%{{{ item.name }}}%}
+    </div>
+  `,
+})
+class DemoComponent {
+  list: Item[];
+
+  trackByTenantAccountId = trackByDeep<Item>('tenant', 'account', 'id');
+}
+```
