Using AngularJS ng-src within an Iframe

I have been trying to dynamically set the source of an iframe using a scope variable, but it keeps appearing blank.

Here is what I attempted:

<div ng-repeat="url in urls">
  <div ng-click="testAlert(url.domain)">
    <iframe ng-src="{{ url.domain }}" ></iframe>
    <div style="text-align: center">{[ url.domain ]}</div>
  </div>
</div>

The text displays correctly, and the click event alerts the selected domain. However, the ng-src appears to be empty causing the site not to load. If I manually enter an external site as the src attribute, it works fine.

Answer №1

It seems like the issue might be related to $sce not being properly configured to trust the external resource during interpolation. You can try adding the following code to your controller (make sure to inject the $sce service). Utilize the trustAsResourceUrl method and pass the URL you wish to use:

.controller("MainController", function ($scope, $sce) {
    var urls = [];

    //In order to interpolate correctly, resources need to be trusted - refer to $sce documentation
    urls.push({domain: $sce.trustAsResourceUrl("http://angularjs.org")});
    urls.push({domain: $sce.trustAsResourceUrl("http://www.jquery.com")});

    $scope.urls = urls;

    $scope.testAlert = function (value) {
        alert(value);
    }
});

Check out this working example on JSFiddle.
