angular2 中的多个组件 [英] Multiple Components in angular2

问题描述

我是 angular 2 的新手，在多个组件中，我在一个文件夹文件中编写了两个组件，我在第一个文件中导入了第二个类，并给出了指令:class 但它显示错误！这里是 app.module.ts 文件

I'm new to angular 2 , In multiple components i have written a two components in a single folder file i have import the 2nd class in first file and given directive: class but its showing error! Here the app.module.ts file

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
@NgModule({
    imports:      [ BrowserModule ],
    declarations: [ AppComponent ],
    bootstrap:    [ AppComponent ]
 })
export class AppModule { }

这里是第一个组件文件 app.component.ts

Here the first component file app.component.ts

import { Component } from '@angular/core';
import { mydetailsComponent } from './app.details';

@Component({
   selector: 'my-app',
   template: `<h1>Welcome to this Application...</h1>
   <p>We have the App details here:</p>
   <mydetails></mydetails>
   `
  directives: [ mydetailsComponent ] })
export class myAppComponent { }

这里是第二个组件文件 app.details.ts

Here second Component file app.details.ts

import { Component } from '@angular/core';
@Component({
  selector: 'mydetails',
  template: `<ul>
             <li>Settings</li>
             <li>Profile</li>
             <li>Games</li>
             <li>Gallery</li>
            `
})
export class mydetailsComponent { }

请告诉我们如何使用和显示多个组件！

推荐答案

在最新的 angular @Component.directives 中已弃用，因此您必须在 中声明您的 mydetailsComponent>AppModule

in latest angular @Component.directives are deprecated so you have to declare your mydetailsComponent in AppModule

app.module.ts

app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { mydetailsComponent }   from './app.details';
@NgModule({
    imports:      [ BrowserModule ],
    declarations: [ AppComponent, mydetailsComponent ],
    bootstrap:    [ AppComponent ]
})
export class AppModule { }

app.component.ts

app.component.ts

import { Component } from '@angular/core';
import { mydetailsComponent } from './app.details';

@Component({
  selector: 'my-app',
  template: `<h1>Welcome to this Application...</h1>
    <p>We have the App details here:</p>
    <mydetails></mydetails>
  `
})
export class myAppComponent { }
