Property Binding is bind property NOT attribute! import {Component, Input, Output, EventEmitter} from 'angular2/core'; @Component({ selector:'hero-item', styles: ['.active {color: red}'], template: `{{hero.name}}` })//export class HeroItem{ label="This is a super hero"; isSelected...
: any)://value为传入的值(即为需要用此管道处理的值, | 前面的值);//args 为传入的参数(?:代表可选);//html 中使用管道格式 - {{ 数据 | 管道名 : 参数1 : 参数2 }}//与 component 一样,pipe 需要先在 declarations 数组中声明后使用
插值表达式:{{ expression }},用于显示组件类中的数据。 属性绑定:[property]="expression",用于绑定组件类中的属性到元素的属性。 事件绑定:(event)="function()",用于绑定组件类中的方法到元素的事件。 服务 服务是 Angular 中用于封装业务逻辑的类,通常用于数据获取、状态管理等。服务可以通过依赖注入系统在整个...
在运行时,Angular会使用NgModuleFactory创建出模块的实例:NgModuleRef。 在NgModuleRef中有一个重要的属性:componentFactoryResolver,它就是刚才那个ComponentFactoryResolver类型的实例,给它一个组件类(类型在运行时的形态,即function),它会给你返回对应的ComponentFactory类型实例。 AOT步骤2.1产生的NgFactories NgFactories是...

程序设计中,UI相关的平台API一般以面向对象为基础,通过属性(Property)或者方法(Method)暴露相关状态及行为,供开发人员使用。UI 编程的本质是花式建立双向绑定,例如对于 元素,其 value 属性往往需要同时被程序读取和写入,同时需要满足读取的结果会作用于下次写入,并且写入的结果会作用于下次读取。如果不满足双向绑定的...
