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‘ }; } /* Copyright 2016 Google Inc. All Rights Reserved. Use of this source code is governed by an MIT-style license that can be found in the LICENSE file at http://angular.io/license */
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 { } /* Copyright 2016 Google Inc. All Rights Reserved. Use of this source code is governed by an MIT-style license that can be found in the LICENSE file at http://angular.io/license */
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/[email protected]?main=browser"></script> <script src="https://unpkg.com/[email protected]/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。
