Javascript 如何聆听角度的属性？

我对这一点表示怀疑。如何侦听同一类中的属性值更改

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})

export class AppComponent  { 
  name:string
}

在您的案例中，处理属性更改的一个简单方法是为您的属性实现getter和setter

示例：

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})

export class AppComponent  { 
  private _name: string

  set name(data) {
    this._name = data;

    // here you can trigger something on data change
    // do something when data is assigned to name
  }

  get name() {
    return this._name;
  }

  //another example for setters as @Input properties
  //here you will act if the component receives input change
  //from a parent component
  @Input
  set name(data: any) {
    this._name = data;

    // here you can trigger something on data change
    // do something when data is assigned to name
  }
}

你想干什么。请解释您的问题当属性更改时，您可以使用typescript setter和getter来执行某些操作。我认为ngOnChanges仅适用于输入属性。
