Angular HTML属性未从Typescript传递到HTML

我是从Typescript发送的

this.equationList = "<span id=\"Weight2\" class=\"weight\">W</span> = mg";

this.equationList=“W=mg”；

到HTML

<div [innerHTML]="equationList"></div>

当我看到inspector中的元素时，我得到的是

<span class="weight">W</span> = mg

W=mg

---

id=“Weight2”无法通过。我尝试在span中发送其他属性。只有class=“weight”成功了。

您是否尝试过父子关系？您可以使用@Outputs将数据从子级传递到父级，也可以使用@Inputs将数据从父级传递到子级

创建一个如下所示的管道：-

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml, SafeStyle, SafeScript, SafeUrl, SafeResourceUrl } from '@angular/platform-browser';

@Pipe({
  name: 'safe'
})
export class SafePipe implements PipeTransform {

  constructor(protected sanitizer: DomSanitizer) {}

 public transform(value: any, type: string): SafeHtml | SafeStyle | SafeScript | SafeUrl | SafeResourceUrl {
    switch (type) {
            case 'html': return this.sanitizer.bypassSecurityTrustHtml(value);
            case 'style': return this.sanitizer.bypassSecurityTrustStyle(value);
            case 'script': return this.sanitizer.bypassSecurityTrustScript(value);
            case 'url': return this.sanitizer.bypassSecurityTrustUrl(value);
            case 'resourceUrl': return this.sanitizer.bypassSecurityTrustResourceUrl(value);
            default: throw new Error(`Invalid safe type specified: ${type}`);
        }
  }
}

使用您的innerHtml，如：-

<div [innerHTML]="equationList|safe: 'html'"></div>

您是否尝试过使用角度表达式

{{}
