Content is what is passed as children. View is the template of the current component. The view is initialized before the content and ngAfterViewInit() is therefore called before ngAfterContentInit(). @Component({ selector: 'parent-cmp', template: '<d…

1.子component中的异步方法 initCreateJob = () => new Promise((resolve, reject) => { setTimeout(() => { this.spiderFormService.saveUserJob(this.spiderJobInfo).subscribe((res: Res) => { if (res.code === 1) { // val = res.data; resolve(res.data) // fn(th…

For example we have a component: class TodoList { private todos: Todo[] = []; add(todo: Todo) {} remove(todo: Todo) {} set(todo: Todo, index: number) {} get(index: number) {} getAll() {} } @Component({ // ... viewProviders: [TodoList] // ... }) class…

*The children element which are located inside of its template of a component are called *view children *. On the other hand, **elements which are used between the opening and closing tags of the host element of a given component are called *content…

11. 变化监测:Angular提供了数据绑定的功能.所谓的数据绑定就是将组件类的数据和页面的DOM元素关联起来.当数据发生变化时,Angular能够监测到这些变化,并对其所绑定的DOM元素 进行相应的更新,反之亦然. 异步事件的发生会导致组件中的数据变化,但Angular并不是捕捉对象的变化,它采用的是在适当的时机去检验对象的值是被改动.这个时机是由NgZone这个服务去掌控的,它获取到了整个 应用的执行上下文,能够对相关的异步事件发生,完成或者异常等进行捕获,然后驱动Angular的变化监测…
