通过更改数据绑定对象的属性来触发OnChanges

import { Component, Input, OnChanges, SimpleChanges } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <div>{{ data }}</div>
  `,
})
export class ExampleComponent implements OnChanges {
  @Input() data: string;

  ngOnChanges(changes: SimpleChanges) {
    if (changes.data) {
      const currentValue = changes.data.currentValue;
      const previousValue = changes.data.previousValue;

      // 执行一些特定的逻辑操作
      console.log('属性data的新值：', currentValue);
      console.log('属性data的旧值：', previousValue);
    }
  }
}
