如何在angular2中实现数组搜索过滤？

<input type="text" [(ngModel)]="searchKeyword" placeholder="Search">

export class MyComponent {
  searchKeyword: string;
  data: any[] = [
    { name: 'John', age: 25 },
    { name: 'Jane', age: 30 },
    { name: 'Bob', age: 35 }
  ];
  filteredData: any[];

  constructor() {
    this.filteredData = this.data;
  }
}

export class MyComponent {
  // ...

  filterData() {
    this.filteredData = this.data.filter(item =>
      item.name.toLowerCase().includes(this.searchKeyword.toLowerCase())
    );
  }
}

<ul>
  <li *ngFor="let item of filteredData">
    {{ item.name }} - {{ item.age }}
  </li>
</ul>

<input type="text" [(ngModel)]="searchKeyword" (input)="filterData()" placeholder="Search">
