Understanding AngularJS ng-src

angularjs, directive

Solution

Put the whole path inside the $scope variable. That way `ng-src` will wait until you provide it with the fully resolved path to the image:

<div ng-controller="MyCtrl">
  <img ng-src="{{ path }}" />
</div>
function MyCtrl($scope, $timeout) {
    var path = 'https://si0.twimg.com/profile_images/';
    $timeout(function () {
        $scope.path = path + '2149314222/square.png';
    }, 1000);
};

FIDDLE

Problem

As explained here, the AngularJS directive ng-src is used to prevent the browser from loading the resource (e.g. image) before the handlebars get parsed. I'm currently using the following code: ``` <div ng-controller="MyCtrl"> <img ng-src="http://localhost:8081/media/{{ path }}" /> </div> ``` With the following JavaScript: ``` function MyCtrl($scope, $timeout) { $timeout(function () { $scope.path = 'images/23694c70-04d7-11e3-9ba8-73fb00de24c4.png'; }, 1000); }; ``` The path is being retrieved from a webservice. Because of this delay, the browser tries to load `http://localhost:8081/media/`, which causes a 404. Once the path is retrieved, the browser issues the correct request and loads the image. What is the preferred method to prevent loading any resources until all data is ready? Please see jsfiddle for an example illustrating my situation.
