Use one way flow syntax property binding:
使用一种方式流语法属性绑定:
<div [innerHTML]="comment"></div>
From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script>
tag but keeps safe content such as the <b>
element."
来自 angular 文档:“Angular 将值识别为不安全并自动对其进行清理,这会删除<script>
标签但保留<b>
元素等安全内容。”
