title: Requesting JSON data with AJAX. I don't see result
body: <p>I'm learning Angular JS. Why I don't see any result?</p>
  
  <p>Here is my example:</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>...
  &lt;div ng-controller="PostsCtrl"&gt;
      &lt;ul ng-repeat="post in posts"&gt;
        &lt;li&gt;{{post.desc}}&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/div&gt;
  ...
  </code></pre>
  
  <p><strong>JS:</strong></p>
  
  <pre><code>var app = angular.module("MyApp", []);
  
  app.controller("PostsCtrl", function($scope, $http) {
    $http.get('http://www.site.com/post?format=json').
      success(function(data, status, headers, config) {
        $scope.posts = data;
      }).
      error(function(data, status, headers, config) {
        // log error
      });
  });
  </code></pre>
  
  <p><strong>JSON</strong> from <a href="http://www.site.com/post?format=json" rel="nofollow noreferrer">http://www.site.com/post?format=json</a>:</p>
