title: Get value from outside ng-repeat in angular
body: <p>How can i get a value from outside an ng-repeat?
  This is my function to get values from json</p>
  
  <pre><code>function($scope, $http) {
          $http.get('https://www.mywebsite.com/images/getimages.php').
            success(function(data, status, headers, config) {
              $scope.walls = data.walls;
              console.log($scope.walls);
           }).error(function(data, status, headers, config) {
              // called asynchronously if an error occurs
              // or server returns response with an error status.
           });
  </code></pre>
  
  <p>then i have a table:</p>
  
  <pre><code>&lt;tr ng-repeat="wall in walls"&gt;
                  &lt;td&gt;{{wall.id}}&lt;/td&gt;
                  &lt;td&gt;&lt;a href="#" ng-click=""&gt;{{wall.link}}&lt;/a&gt;&lt;/td&gt;            
              &lt;/tr&gt;
  </code></pre>
  
  <p>i would show in a div outside the table and so outside the ng-repeat, the {{wall.link}} selected from the td. How can i do it?</p>
