问题描述:要使用angular获取一个HTML格式且含有style样式的字符串javascript
首先,angular输出html格式的字符串(note)的实现方法为:html
<div [innerHTML]="note" ></div>
可是,运行代码后发现,这样并不可以将note字符串中的style样式显示出来。java
angular输出带有style样式的html格式的字符串的实现方法为:ionic
1.自定义一个HtmlPipe类ide
import {Pipe, PipeTransform} from "@angular/core"; import {DomSanitizer} from "@angular/platform-browser"; @Pipe({ name: "html" }) export class HtmlPipe implements PipeTransform{ constructor (private sanitizer: DomSanitizer) { } transform(style) { return this.sanitizer.bypassSecurityTrustHtml(style); } }
2.在须要的模块中引入管道HtmlPipethis
import { NgModule } from '@angular/core'; import { IonicPageModule } from 'ionic-angular'; import { HtmlInfoPage } from './html-info'; import {EmptyViewComponentModule} from "../../../components/empty-view/empty-view.module"; import {HtmlPipe} from "../../../providers/pipe"; @NgModule({ declarations: [ HtmlInfoPage, HtmlPipe ], imports: [ IonicPageModule.forChild(HtmlInfoPage), EmptyViewComponentModule ], exports: [ HtmlInfoPage ] }) export class HtmlInfoPageModule {}3.在innerHTML中增长管道名称
<div [innerHTML]="note | html" ></div>这样就可以显示含有style样式的HTML文本。
