How to Trust and Set iFrame Src Attribute from a Variable in AngularJS?

Setting iFrame Src Attribute from a Variable in AngularJS

In AngularJS, you may encounter challenges when attempting to set the src attribute of an iFrame from a variable. To address this issue, we must delve into the provided code:

<br>function AppCtrl($scope) {<pre class="brush:php;toolbar:false">$scope.projects = {

    1 : {
        "id" : 1,
        "name" : "Mela Sarkar",
        "url" : "http://blabla.com",
        "description" : "A professional portfolio site for McGill University professor Mela Sarkar."
    },

    2 : {
        "id" : 2,
        "name" : "Good Watching",
        "url" : "http://goodwatching.com",
        "description" : "Weekend experiment to help my mom decide what to watch."    
    }
};

$scope.setProject = function (id) {
    $scope.currentProject = $scope.projects[id];
    console.log( $scope.currentProject );

}

}

The crux of the issue lies in the absence of the trustSrc function referenced in the ng-src attribute. You need to inject the $sce service into the controller to utilize the trustAsResourceUrl method for sanitizing the URL string.

<br>function AppCtrl($scope, $sce) { // Injected $sce service<pre class="brush:php;toolbar:false">// ...

$scope.setProject = function (id) {
  $scope.currentProject = $scope.projects[id];
  $scope.currentProjectUrl = $sce.trustAsResourceUrl($scope.currentProject.url);
  console.log( $scope.currentProject );
  console.log( $scope.currentProjectUrl );

}

}

Within the template:

<br><iframe ng-src="{{currentProjectUrl}}"> <!--content--> </iframe><br>

By employing trustAsResourceUrl, you can safely set the URL within the src attribute.
