Utilizing string interpolation in Angular 2 and 4

Can anyone advise on the best way to use a variable named multicolors that is defined in a typescript file within our template? I attempted using it like this, but unfortunately it did not work:

-webkit-linear-gradient(135deg, {{multicolors}} 50%, lightgray 50%)
. Any suggestions or solutions?

Answer №1

To create a custom pipe for safe styling, you can do the following:

@Pipe({ name: 'safeStyle' })
export class SafeStylePipe implements PipeTransform {
  constructor(private sanitizer: DomSanitizer) {}
  transform(style) {
    return this.sanitizer.bypassSecurityTrustStyle(style);
  }
}

After creating the pipe, you can use it like this:

<div [style.background]="'-webkit-linear-gradient(135deg, ' + multicolors + ' 50%, lightgray 50%)' | safeStyle">
  Test
</div>
