Directive not working on Mozilla Firefox

Currently, I have a directive set up to display an image as a background image. This works perfectly fine in Chrome and Safari, but for some reason, it doesn't seem to be functioning properly in Firefox as the background images are not showing up. After doing some research, it seems like using scope.$watch may potentially help resolve this issue. However, I'm unsure of how to properly implement it in order to improve the situation.

.directive('pictures', function () {
    return {
      restrict: 'EA',
      link: function (scope, element, attrs) {
       var url = attrs.pictures;
                element.css({
            'background-image': 'url(' + url +')',
            'background-size' : 'cover'
          });
      }
    };
  });

I would greatly appreciate any assistance or guidance on this matter. Thank you.

Answer №1

It appears that there may be some issue with the " characters in the background-image URL property.

Snippet of Code

.directive('pictures', function () {
    return {
      restrict: 'EA',
      link: function (scope, element, attrs) {
       var url = attrs.pictures;
                element.css({
            'background-image': 'url("' + url +'")', <-- This part needs to be adjusted
            'background-size' : 'cover'
          });
      }
    };
  });

If the value in the photos property is set asynchronously, it's important to use scope.$watch to monitor it and apply the background image after the value has been assigned. In some cases, it may seem like luck that the value was already set in Chrome and Safari by the time the link function of your directive ran.

For example, if your HTML markup looks like this:

<div class="picture" photos="images[0].photoUrl"></div>

and your images array is populated via an AJAX request, then your directive would resemble the following:

.directive('photos', function () {
  return {
    restrict: 'EA',
    link: function (scope, element, attrs) {

       // The attribute might not be set yet, so watch it using $watch

       scope.$watch(attrs.photos, function (newVal, oldVal) {
         if (!newVal || (newVal === oldVal)) {
           return;
         }

          element.css({
            'background-image': 'url(' + newVal +')',
            'background-size' : 'cover'
          });

       });
    }
  };
});

You can see a working example on Plunker.

The solution turned out to be quite surprising - simply including "display:block" in the img tag's CSS did the trick. A big thank you to everyone who contributed their assistance.
