AfterContentInit
一个生命周期钩子,它会在 Angular 完全实例化了指令的所有内容之后调用。 定义一个 ngAfterContentInit()
方法来处理额外的初始化任务。
A lifecycle hook that is called after Angular has fully initialized all content of a directive. Define an ngAfterContentInit()
method to handle any additional initialization tasks.
interface AfterContentInit {
ngAfterContentInit(): void
}

使用说明
下列代码展示了组件如何实现该接口,并定义它自己的内容初始化逻辑。
The following snippet shows how a component can implement this interface to define its own content initialization method.
@Component({selector: 'my-cmp', template: `...`})
class MyComponent implements AfterContentInit {
ngAfterContentInit() {
// ...
}
}
