Angular4.x创建使用服务
一、 Angualr CLI创建服务
Scaffold | Usage |
---|---|
Component | ng g component my-new-component |
Service | ng g service my-new-service |
二、创建服务命令
ng g service my-new-service
创建到指定目录下面
ng g service services/storage
三、app.module.ts里面引入创建的服务
1.app.module.ts 里面引入创建的服务
import { StorageService } from './services/storage.service';
- NgModule 里面的providers 里面依赖注入服务
@NgModule({
declarations: [
AppComponent,
HeaderComponent,
FooterComponent,
NewsComponent,
TodolistComponent ],
imports: [
BrowserModule,
FormsModule
],
providers: [StorageService],
bootstrap: [AppComponent]
})
export class AppModule { }
四、使用的页面引入服务,注册服务
import { StorageService } from '../../services/storage.service';
constructor(private storage: StorageService) { }
使用
addData(){
// alert(this.username);
this.list.push(this.username);
this.storage.set('todolist',this.list);
}
removerData(key){
console.log(key);
this.list.splice(key,1);
this.storage.set('todolist',this.list);
}
