Angular.js Data-bind Background Images Using Media Queries

I have an Angular.js application with dynamically background images (should have data-binding for their URL). I also want to use css media queries in order to detect orientation/pi

Solution 1:

This is just a starting point solving your problem.

You may use matchMedia: https://developer.mozilla.org/en-US/docs/Web/API/Window.matchMedia

if (window.matchMedia("(min-width: 400px)").matches) {
    $scope.poster = 'small.png';
} else {
    $scope.poster = 'big.png';
}

now you can use it in the html file:

<divclass="moments-preview-image"ng-style="{'background-image': 'url('+poster+ ')'}"> ... </div>

If your browser doesn't support this new API you may have a look on some interesting workarounds:
