Angular2 innerHtml 去除样式

Question

我正在使用 innerHtml 并在我的 cms 中设置 html 响应似乎没问题，如果我这样打印它: {{ poi.content }}

它给了我正确的内容:`

<table border="0" cellpadding="5" cellspacing="0">
   <tbody>
     <tr>
       <td style="vertical-align: top;">Tes11t</td>
       <td style="width: 2px;">&nbsp;</td>
       <td style="width: 1px;"><img alt="midgetgolf-sport-faciliteiten-vakantiepark-2.jpg" src="http://beeksebergen.dev/app_dev.php/media/cache/resolve/full_size/midgetgolf-sport-faciliteiten-vakantiepark-2.jpg" style="height: 67px; width: 100px;" /></td>
      </tr>
    </tbody>
 </table>

`

但是当我使用 [innerHtml]="poi.content" 时，它会返回这个 html:

<table border="0" cellpadding="5" cellspacing="0">
    <tbody>
        <tr>
            <td>Tes11t</td>
            <td>&nbsp;</td>
            <td><img alt="midgetgolf-sport-faciliteiten-vakantiepark-2.jpg" src="http://beeksebergen.dev/app_dev.php/media/cache/resolve/full_size/midgetgolf-sport-faciliteiten-vakantiepark-2.jpg"></td>
        </tr>
    </tbody>
</table>

有谁知道为什么当我使用 [innerHtml]

时它会剥离我的样式

Angular2 清理动态添加的 HTML、样式...

@Pipe({name: 'safeHtml'})
export class Safe {
  constructor(private sanitizer:DomSanitizer){}

  transform(html) {
    return this.sanitizer.bypassSecurityTrustHtml(html);
  }
}

[innerHtml]="poi.content | safeHtml"

见

• In RC.1 some styles can't be added using binding syntax了解更多详情。
