Angular bind object element to HTML

Question

I got the code from another question and it's straightforward and working fine

<div ng-controller="ExampleController">
<p ng-bind-html="testHTML"></p>
(function(angular) {
  'use strict';
  angular.module('bindHtmlExample', ['ngSanitize'])
  .controller('ExampleController', ['$scope', function($scope) {
       $scope.testHTML = 'I am an <code>HTML</code>string with ' +
                         '<a href="#">links!</a> and other <em>stuff</em>';
  }]);
})(window.angular);

Suppose, I'm getting an object and I want to show an element of the object

var obj = {
   title: 'Title',
   description: 'I am an <code>HTML</code>string with ' +
       '<a href="#">links!</a> and other <em>stuff</em>'
};
$scope.testHTML = obj;

Then how should I bind only the description on the html end? I've tried and 

plnkr example

Did you assign $scope.testHTML = obj, then var obj = {...} in your code ? — Vo Kim Nguyen, Sep 08 '16 at 02:59

Try this snippet to bind HTML

Firstly, you can create custom filter to bind the HTML in AngularJS.

Now, you can use this filter anywhere into the myApp module by just writing yourHTML | html, That will done the job.

var myApp = angular.module('myApp',[]);
myApp.controller('GreetingController', ['$scope','$sce', function($scope, $sce) {
  var obj = {
     title: 'Title',
     description: 'I am an <code>HTML</code>string with ' +
       '<a href="#">links!</a> and other <em>stuff</em>',
     description1: 'I am an <b>HTML</b>string with ' +
       '<a href="#">links!</a> and other <u><b>stuff</b></u>'
    
  };
  $scope.testHTML = obj;
  
  //Use $SCE in controller
  var preview_data = obj.description;
  $scope.htmlSafe = $sce.trustAsHtml(preview_data);
  
}]);
//Custom filter (Alternate way)
myApp.filter('html', ['$sce', function ($sce) { 
    return function (text) {
        return $sce.trustAsHtml(text);
    };    
}])

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="GreetingController">
  
  <b>By using custom filter</b>
  <div ng-bind-html="testHTML.description | html"></div>
  <div ng-bind-html="testHTML.description1 | html"></div>

  <br/>
  <b>By using $SCE inside controller</b>
  <div ng-bind-html="htmlSafe"></div>

</div>

Console's saying $sce.trustAsHTML is not a function – marukobotto Sep 08 '16 at 07:03
I've created the snippet that is working, if you can check that. or provide me your jsfiddle. – Mohit Tanwani Sep 08 '16 at 07:05
Which version of Angular Js you're using ? it should be 1.2 at least – Mohit Tanwani Sep 08 '16 at 07:07
@SagnikChakraborti I've updated my answer and added two ways to do this. – Mohit Tanwani Sep 08 '16 at 07:18
Thank You. It's working fine now. Had a problem in my code. However, with `ngSanitize` iframe wasn't showing. I don't know why but I'm curious. Now it's showing perfectly. :) – marukobotto Sep 08 '16 at 07:27
@SagnikChakraborti Glad to see that it helped you :) – Mohit Tanwani Sep 08 '16 at 07:41

ng-bind-html doesn't require interpolation as it accepts an expression, so you only need to set it to testHtml.desc without the curly braces {{}}.

In your plunkr's controller you're assigning obj to $scope.testHtml before you declare obj itself, so it won't render anything since obj is undefined at assignment.
