Utilizing Angular 2+ with the [innerHTML] property to incorporate HTML with added style attributes

I am currently utilizing Angular 2+ [innerHTML] input for inserting HTML formatting that includes style tags.

Within my template, the code looks like this:

<span [innerHTML]="someVar"></span>

In the component file, I have defined:

someVar = `<span style="background-color:#990000">test</span>`;

A warning message is displayed:

WARNING: sanitizing HTML stripped some content (see http://g.co/ng/security#xss).

The output showcases the inserted span element with the style attribute removed.

To address this issue, I followed a solution mentioned in this post:

https://stackoverflow.com/questions/37076867/

The implementation involves creating a pipe as shown below:

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

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

  transform(html): SafeHtml {
    // return this.sanitizer.bypassSecurityTrustStyle(style);
    return this.sanitizer.bypassSecurityTrustHtml(html);
    // return this.sanitizer.bypassSecurityTrustScript(value);
    // return this.sanitizer.bypassSecurityTrustUrl(value);
    // return this.sanitizer.bypassSecurityTrustResourceUrl(value);
  }
}

However, despite implementing the suggested solution, there seems to be no change in the output. It is unclear if I am using it correctly...

Can anyone guide me on how to maintain the style attribute while using innerHTML in Angular?

Answer №1

Just a little more to go! Ensure that you are utilizing your pipe for your HTML string.

Here is an example pipe code snippet:

import {Pipe} from '@angular/core'; 
import {DomSanitizer, SafeHtml, SafeStyle, SafeScript, SafeUrl, SafeResourceUrl} from '@angular/platform-browser';
@Pipe({
name: 'safe'
})
export class SafePipe {

constructor(protected sanitizer: DomSanitizer) {}

  transform(htmlString: string): any {
    return this.sanitizer.bypassSecurityTrustHtml(htmlString);
  }
}

Example of how to use this safe pipe:

<span [innerHTML]="someVar | safe"></span>

I hope this explanation clarifies things for you!

Whether you opt for utilizing this filter or implementing the functionality directly in your code is up to you.

To incorporate the filter, simply include it in your HTML as shown below:

<div [innerHTML]="someContent | customFilter"></div>
