inserting iframe from trusted source in AngularJS

问题:

Trying to use ng-bind-html to insert iframe into page with AngularJS & I can't get it to work it on even the simplest form.

Javascript

function Ctrl($scope) {
   $scope.showIt = '<iframe src="http://www.anything.com"></iframe>';
}

My HTML:

<div ng-bind-html="showIt"></div>

You need to use $sce service to tell angular to render html content on view

Angular Doc says

$sce is a service that provides Strict Contextual Escaping services to AngularJS. SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.

Before doing it, you need to inject ngSanitize dependency inside your app

You can do it in two way either using filter or controller

HTML

<div ng-app="app" ng-controller="mainCtrl">
    Using Filter
    <div ng-bind-html="showIt | toTrusted"></div>
    Using Controller
    <div ng-bind-html="htmlSafe(showIt)"></div>
</div>

JavaScript Code

var app = angular.module('app', ['ngSanitize']).
controller('mainCtrl', function ($scope, $sce) {
    $scope.showIt = '<iframe src="http://www.anything.com"></iframe>';
    $scope.htmlSafe = function (data) {
        return $sce.trustAsHtml(data);
    }
}).
filter('toTrusted', function ($sce) {
    return function (value) {
        return $sce.trustAsHtml(value);
    };
});

From angular 1.2 onwards $sce feature is enabled for below version you should enable/disable it in config phase of angular.

app.config(['$sceProvider', function($sceProvider) {
    $sceProvider.enabled(true);
}]);

Here is Working Fiddle
