使用多个关键点过滤Angular2中的映射

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'multiFilter'
})
export class MultiFilterPipe implements PipeTransform {

  transform(items: any[], searchText: string): any[] {
    if (!items) return [];
    if (!searchText) return items;

    searchText = searchText.toLowerCase();

    return items.filter(item => {
      // 假设每个item都有name和description属性
      return item.name.toLowerCase().includes(searchText) ||
             item.description.toLowerCase().includes(searchText);
    });
  }
}

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

<ul>
  <li *ngFor="let item of items | multiFilter: searchText">
    {{ item.name }} - {{ item.description }}
  </li>
</ul>
