Hold off on compiling the Angular directive template until the function has finished executing

I created an angular directive that dynamically displays an image on my webpage based on the value in a querystring within the URL:

app.directive('myDirective', function(myService) {
    return {
        restrict: 'A',
        replace: true,
        scope: true,
        link: function($scope, element, attrs) {

            var myImage = myService.getParam();

            if (myImage == AA3) {
                $scope.myImage = 'YAHOO';
            }
            else {
                $scope.myImage = 'capitalone';
            }

        },
        template : '<img src="/resources/{{myImage}}.png" />'
    };
});

The issue I'm facing is that I can see 2 separate HTTP requests being made:

1. http://www.mydom.net/resources/{{myImage}}.png
2. http://www.mydom.net/resources/YAHOO.png

Is there a way for me to delay the compilation of the template until the variable myImage actually contains a value?

Answer №1

Make sure to utilize ng-src in place of src attribute.

<img ng-src="/images/{{selectedImage}}.jpg" />

Answer №2

It's best practice to utilize ng-src in place of src

template : '<img ng-src="/assets/{{myImage}}.jpg" />'

Answer №3

ng-src is the perfect solution for this situation.

template : '<img ng-src="/images/{{imagePath}}.png" />'
