在 Angular 中使用管道过滤多个属性

Question

我使用教程使用结果表中的单个属性(名称(过滤搜索，以及什么工作方式符合我想要的方式，但是我如何调整管道以搜索多个属性(即物种名称、外壳名称等(？

管：

import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'filter'
})
export class FilterPipe implements PipeTransform {
transform(items: any[], searchText: string): any {
if(!items) return [];
if(!searchText) return items;
searchText = searchText.toLowerCase();
return items.filter( it => {
return it.Name.toLowerCase().includes(searchText);
});
}
}

.HTML：

<section>
<div class="toolbar">
<input id="fur-filter" [(ngModel)]="searchText" class="filter" placeholder="FILTER ANIMALS, SPECIES, ENCLOSURES, TEMPERAMENTS ETC." />
<button id="AddNewAnimal" class="ko-btn">Add New Animal</button>
<button id="InspectionReport" class="ko-btn">Start Inspection Report</button>
</div> 
<div class="list-container">
<div class="animal-row" *ngFor="let furries of animalsFur | filter : searchText">
<img [src]="furries.avatar" />
<div class="animal-info">
<p>{{furries.Name}} {{furries.Nickname}}</p>
<div class="row">
<div id="species" class="col">
<p id="species-text">Species: <span>{{furries.SpeciesName}}</span></p>
</div>
<div class="col">
<p>Sub-Species: <span>{{furries.SubSpeciesName}}</span></p>
</div>
<div class="col">
<p>Arrived: <span>{{furries.Welcomed}}</span></p>
</div>
<div class="col">
<p>Age: <span>{{furries.Age}} Years</span></p>
</div>
<div class="col">
<p>Enclosure: <span>{{furries.EnclosureName}}</span></p>
</div>
<div class="col">
<p>Temperament: <span>{{furries.Temperament}}</span></p>
</div>
</div>
</div>
</div>
</div>
</section>

Answer 1

您只需使用&&(和(或||(或(来解决此问题：

return items.filter( it => {
return it.Name.toLowerCase().includes(searchText) 
|| it.SpeciesName.toLowerCase().includes(searchText) // add more conditions
});

Answer 2

将 return 语句替换为：

return it.Name.toLowerCase().includes(searchText)||
it.Nickname.toLowerCase().includes(searchText)||
it.SpeciesName.toLowerCase().includes(searchText)||
