Converting a string to an HTML object in Angular using Typescript and assigning it to a variable

I am facing an issue with passing HTML content from a service to a div element. I have a function that fetches HTML content as a string from a file and converts it into an HTML object, which I can see working in the console. However, when trying to assign this HTML object to a variable in my service, I encounter an error.

nav.service.ts:

html: string;
      public getZipFileContent(urlPath:string, pathInZip:string) {
        getFileContentFromRemoteZip(urlPath, pathInZip, (content) => {
          console.log(content);
          let html = content; 
          let htmlObject = document.createElement('div');
          htmlObject.innerHTML = html;
          console.log(htmlObject);
          this.html = html; // it's a string
          this.html = htmlObject // error : can't assign string as HTMLDivElement
        });
      }
    }

In my component, by adding {{navSrv.html}}, currently I get:

However, I would like to display:

Hello

Based on the console log from console.log(htmlObject);

How can I retrieve the htmlObject and use it as a variable?

Answer №1

here is a way to achieve this using only div tag:

<div [innerHtml]="navSrv.html"></div>

Alternatively, you can also do it like this :

<div #divID ></div>

Then, you can bind it in the following manner:

@ViewChild('divID') divID: ElementRef;

loadHtml(){
    this.divID.nativeElement.innerHTML = this.html;
}

The second approach is beneficial when dealing with large html strings.

UPDATE:

If there are <script> tags in your content, you can handle it as shown below:

const element = document.createRange().createContextualFragment(this.html);
this.divID.appendChild(fragment);

Answer №2

To ensure that your HTML is displayed correctly, you can utilize the innerHTML property:

<div [innerHTML]="navSrv.html"></div>
