如果你想通过其他字段过滤,只需将它们添加到管道中：

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

@Pipe({
    name: 'searchFilter'
})
export class SearchFilter implements PipeTransform {
    transform(items: any[],criteria: any): any {

        return items.filter(item =>{
           for (let key in item ) {
             if((""+item[key]).toLocaleLowerCase().includes(criteria.toLocaleLowerCase())){
                return true;
             }
           }
           return false;
        });
    }
}

    @Component({
      selector: 'sites-component',template: `
        <input #search  (keyup)="0">
        <ul>
          <li *ngFor="let site of (sites | searchFilter: search.value )">(...)</li>
        </ul>
      `
    })
    export class SitesComponent{
       sites : Array;
    }

别忘了在模块中声明管道.
