Looking for assistance with html encoding in angular 4. I have product records stored in a database, with the fullDescription field in this particular format:
<div align="justify"><span>
When using
<div *ngIf="product" [innerHTML]="product.fullDescription"></div><div align="justify"><span>
displayed as text. Is there a way to render this as innerHtml instead of plain text?
Thank you in advance.
To decode HTML entities in your component's class, you can create a function like the following:
decodeHTML(input) : any {
return new DOMParser().parseFromString(input, "text/html").documentElement.textContent;
}
Then in the template, you can use it as follows:
<div *ngIf="content" [innerHTML]="decodeHTML(content.fullContent)"></div>
I successfully completed this task using a custom pipe.
To achieve this, I created a component.ts file and added the following code:
import { Pipe, PipeTransform, SecurityContext } from '@angular/core';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';
@Pipe({ name: 'sanitizeHtml', pure: false })
export class SanitizeHtmlPipe implements PipeTransform {
constructor(private sanitizer: DomSanitizer) { }
transform(data): SafeHtml {
return this.sanitizer.sanitize(SecurityContext.HTML, data);
}
}
Next, in app.module.ts:
Import { SanitizeHtmlPipe } from './pagecontent/pagecontent.component';
Add SanitizeHtmlPipe to the declarations[] array
Finally, in component.html:
<span [innerHTML]="data | sanitizeHtml"></span>
And there you have it! Everything is now set up as needed. :) :)
The solution provided above was a step in the right direction towards resolving my issue. In addition to those adjustments, I found that making changes to the code below was crucial in successfully loading an encoded string of HTML with inline styles into a div element.
Modifications to the HTML code:
<div *ngIf="item" id="descriptionContainer" #descriptionContainer></div>
Updates made to the Angular component.ts file:
@ViewChild('descriptionContainer', { static: true }) descriptionContainer: ElementRef;
loadContent() {
this.descriptionContainer.nativeElement.innerHTML =
this.toMarkup('<div align="justify" style="color:blue;"><span>');
}
toMarkup(input) : any {
return new DOMParser().parseFromString(input, "text/html").documentElement.textContent;
}
I believe these changes could be beneficial to someone facing a similar challenge. Thank you!
