一、Angualr CLI 创建服务
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';
2. 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);
}
