Background url

Ionic Framework ionic-v3
1

Hi there,

My trouble is that when I print the image url like so

{{ imagesFolder + selectedSampleType.image }}

or like so

src=“{{ imagesFolder + selectedSampleType.image }}”

it works. But I need to use it as a background for the div, which returns “undefined” for me:

[ngStyle]=“{‘background’: ‘url(’ + imagesFolder + selectedSampleType.image + ‘)’}”

What am I doing wrong here?

Thanks,
Olga
