Solution 1:

It is possible to parse dynamic values in a couple of way.

Interpolation with double-curly braces:

ng-style="{'background-image':'url({{myBackgroundUrl}})'}"

String concatenation:

ng-style="{'background-image': 'url(' + myBackgroundUrl + ')'}"

ES6 template literals:

ng-style="{'background-image': `url(${myBackgroundUrl})`}"

Solution 2:

Correct syntax for background-image is:

background-image: url("path_to_image");

Correct syntax for ng-style is:

ng-style="{'background-image':'url(https://www.google.com/images/srpr/logo4w.png)'}">

Solution 3:

IF you have data you're waiting for the server to return (item.id) and have a construct like this:

ng-style="{'background-image':'url(https://www.myImageplusitsid/{{item.id}})'}"

Make sure you add something like ng-if="item.id"

Otherwise you'll either have two requests or one faulty.

Solution 4:

For those who are struggling to get this working with IE11

HTML

<div ng-style="getBackgroundStyle(imagepath)"></div>

JS

$scope.getBackgroundStyle = function(imagepath){
    return {
        'background-image':'url(' + imagepath + ')'
    }
}

Solution 5:

This worked for me, curly braces are not required.

ng-style="{'background-image':'url(../../../app/img/notification/'+notification.icon+'.png)'}"

notification.icon here is scope variable.
