angular2/ionic2 实现搜索结果中的搜索关键字高亮的示例

import { Pipe, Injectable, PipeTransform } from '@angular/core';import { DomSanitizer } from '@angular/platform-browser';@Pipe({ name: 'keyword'})@Injectable()export class KeywordPipe implements PipeTransform { constructor(private sanitizer: DomSanitizer) { } transform(val: string, keyword: string): any {  const Reg = new RegExp(keyword, 'i');  if (val) {   const res = val.replace(Reg, `<span style="color: #81E1B7;">${keyword}</span>`);   console.log(res);   return this.sanitizer.bypassSecurityTrustHtml(res);  } }}

<ion-label [innerHTML]="item.name | keyword:searchText"></ion-label>
