## 场景 ##

Ionic介绍以及搭建环境、新建和运行项目：

[https://blog.csdn.net/BADAO\_LIUMANG\_QIZHI/article/details/106308166][https_blog.csdn.net_BADAO_LIUMANG_QIZHI_article_details_106308166]

在上面搭建起Ionic项目后 。

Ionic创建页面以及页面之间跳转、页面添加返回按钮、新增底部页面：

实现页面的跳转后。

怎样把公共的功能抽离出来成为一个模块，然后在其他模块中引入这个公共的模块？

## 实现 ##

新建公共模块以及组件

ionic g module module/list

ionic g component module/list

公共模块list.module.ts中暴露对应的组件

import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { ListComponent } from './list.component';
    
    
    @NgModule({
      declarations: [],
      imports: [
        CommonModule
      ],
      exports:[ListComponent]
    })
    export class ListModule { }

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

用到的地方引入自定义模块，并依赖注入自定义模块

这里在tab2.module.ts中引入

import { IonicModule } from '@ionic/angular';
    import { RouterModule } from '@angular/router';
    import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { FormsModule } from '@angular/forms';
    import { Tab2Page } from './tab2.page';
    import { ExploreContainerComponentModule } from '../explore-container/explore-container.module';
    
    import { Tab2PageRoutingModule } from './tab2-routing.module';
    import { ListModule } from '../module/list/list.module';
    @NgModule({
      imports: [
        IonicModule,
        CommonModule,
        FormsModule,
        ExploreContainerComponentModule,
        Tab2PageRoutingModule,
        ListModule
      ],
      declarations: [Tab2Page]
    })
    export class Tab2PageModule {}

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

使用自定义模块

为了能更好辨别是使用的公共模块在公共模块list.component.html中修改为

然后在tab2.page.html中使用公共模块

<app-list></app-list>

### Ionic自定义模块中使用内置模块 ###

Ionic的内置模块

[http://www.ionic.wang/components\_doc-index.html][http_www.ionic.wang_components_doc-index.html]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

只需要在自定义公共模块这里是list.module.ts中引入并声明Ionic内置模块

import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { ListComponent } from './list.component';
    import { IonicModule } from '@ionic/angular';
    
    @NgModule({
      declarations: [],
      imports: [
        CommonModule,
        IonicModule
      ],
      exports:[ListComponent]
    })
    export class ListModule { }

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 5][]

然后就可以在自定义模块这里是list.component.html中使用ionic的内置模块了
