突出显示角度2的搜索文本

我是Angular 2的新手.我正在尝试完成与突出显示搜索文本相同的任务- 角度2上面提到的内容.我已经创建了管道过滤器我的问题是我应该在哪里保留管道过滤器以及我应该在哪里放置内部html div.

复制问题:

信使根据用户提供的输入显示搜索结果.在显示结果时,需要突出显示已搜索的单词.这些是使用的html和组件.

component.html

Id : result.id 
Summary : result.summary 
 Link : result.link 

Component.ts

resultArray : any = [{"id":"1","summary":"These are the results for the searched text","link":"http://www.example.com"}]

通过发送搜索文本作为输入来获取此resultArray来命中后端服务.根据搜索文本,获取结果.需要突出显示搜索到的文字,类似于谷歌搜索.

我应该如何应用搜索过滤器以及我应该在哪里保留内部html？

有关案例的正则表达式替换有一些调整,但这是一个起点:

//our root app component
import {Component, NgModule, VERSION, Pipe, PipeTransform} from '@angular/core'
import {BrowserModule, DomSanitizer} from '@angular/platform-browser'

@Pipe({
    name: 'highlight'
})
export class HighlightSearch implements PipeTransform {
  constructor(private sanitizer: DomSanitizer){}

  transform(value: any, args: any): any {
    if (!args) {
      return value;
    }
    // Match in a case insensitive maneer
    const re = new RegExp(args, 'gi');
    const match = value.match(re);

    // If there's no match, just return the original value.
    if (!match) {
      return value;
    }

    const result = value.replace(re, "" + match[0] + "");
    return this.sanitizer.bypassSecurityTrustHtml(result);
  }
}

@Component({ 
  selector: 'my-app',
  template: `
    
    

  `,
})
export class App {
  results: string[]
  searchTerm: string;
  constructor() {
    this.resultArray = [
      {
        "id": "1",
        "summary": "These are the results for the searched text",
        "link": "http://www.example.com"
      },
      {
        "id": "2",
        "summary": "Here are some more results you searched for",
        "link": "http://www.example.com"
      }
    ]
  }
  updateSearch(e) {
    this.searchTerm = e.target.value
  }
}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App, HighlightSearch ],
  bootstrap: [ App ]
})
export class AppModule {}
