I was recently creating a web application using Angular 5.
I have built most of the thing but when I was required to add a <script>
in my component template the code didn't work at compile time.
Can anybody suggest a solution?
html
<section class="col span-2-of-6 ads">
<div [innerHtml]="html | safe: 'html'" ></div>
</section>
component
html : string = "<script type='text/javascript' language='javascript' src=''></script>"; //ads js src in src=""
safe.pipe.ts
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}`);
}
}
}
When I used the developer options in Chrome, I found that display
is none
in the template component.
script { user agent stylesheet
display: none;
}
