初识angular2,根据官网所示，代码目录如图
1、先是app.component.ts代码
import { Component } from ‘@angular/core‘;
export class Hero {
id: number;
name: string;
}
@Component({
selector: ‘my-app‘,
template: `
<h1>{{title}}</h1>
<h2>{{hero.name}} details!</h2>
<div><label>id: </label>{{hero.id}}</div>
<div>
<label>name: </label>
<input [(ngModel)]="hero.name" placeholder="name">
</div>
`
})
export class AppComponent {
title = ‘Tour of Heroes‘;
hero: Hero = {
id: 1,
name: ‘Windstorm‘
};
}

2、module.ts的代码
import { NgModule } from ‘@angular/core‘;
import { BrowserModule } from ‘@angular/platform-browser‘;
import { FormsModule } from ‘@angular/forms‘;
import { AppComponent } from ‘./app.component‘;
@NgModule({
imports: [
BrowserModule,
FormsModule
],
declarations: [
AppComponent
],
bootstrap: [ AppComponent ]
})
export class AppModule { }

3、index.html
<!DOCTYPE html>
<html>
<head>
<title>Angular Tour of Heroes</title>
<script>document.write(‘<base href="‘ + document.location + ‘" />‘);</script>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles.css">
<!-- Polyfills -->
<script src="https://unpkg.com/core-js/client/shim.min.js"></script>
<script src="https://unpkg.com/zone.js@0.7.4?main=browser"></script>
<script src="https://unpkg.com/systemjs@0.19.39/dist/system.src.js"></script>
<script src="https://cdn.rawgit.com/angular/angular.io/b3c65a9/public/docs/_examples/_boilerplate/systemjs.config.web.js"></script>
<script>
System.import(‘main.js‘).catch(function(err){ console.error(err); });
</script>
</head>
<body>
<my-app>Loading...</my-app>
</body>
</html>
4、main.ts
import { platformBrowserDynamic } from ‘@angular/platform-browser-dynamic‘;
import { AppModule } from ‘./app/app.module‘;
platformBrowserDynamic().bootstrapModule(AppModule);
5、css部分
/* Master Styles */ h1 { color: #369; font-family: Arial, Helvetica, sans-serif; font-size: 250%; } h2, h3 { color: #444; font-family: Arial, Helvetica, sans-serif; font-weight: lighter; } body { margin: 2em; } body, input[text], button { color: #888; font-family: Cambria, Georgia; } a { cursor: pointer; cursor: hand; } button { font-family: Arial; background-color: #eee; border: none; padding: 5px 10px; border-radius: 4px; cursor: pointer; cursor: hand; } button:hover { background-color: #cfd8dc; } button:disabled { background-color: #eee; color: #aaa; cursor: auto; } /* Navigation link styles */ nav a { padding: 5px 10px; text-decoration: none; margin-right: 10px; margin-top: 10px; display: inline-block; background-color: #eee; border-radius: 4px; } nav a:visited, a:link { color: #607D8B; } nav a:hover { color: #039be5; background-color: #CFD8DC; } nav a.active { color: #039be5; } /* items class */ .items { margin: 0 0 2em 0; list-style-type: none; padding: 0; width: 24em; } .items li { cursor: pointer; position: relative; left: 0; background-color: #EEE; margin: .5em; padding: .3em 0; height: 1.6em; border-radius: 4px; } .items li:hover { color: #607D8B; background-color: #DDD; left: .1em; } .items li.selected { background-color: #CFD8DC; color: white; } .items li.selected:hover { background-color: #BBD8DC; } .items .text { position: relative; top: -3px; } .items .badge { display: inline-block; font-size: small; color: white; padding: 0.8em 0.7em 0 0.7em; background-color: #607D8B; line-height: 1em; position: relative; left: -1px; top: -4px; height: 1.8em; margin-right: .8em; border-radius: 4px 0 0 4px; } /* everywhere else */ * { font-family: Arial, Helvetica, sans-serif; }
以上是官网实现的入门级，相当于angualr1中双向数据绑定的功能实现。
