AngularJs And Facebook Comments

Post a Comment
I'm trying to dynamically update the review of facebook on my html , however is not showing , follow my Plunker. WHAT can be done to render the comments ? http://plnkr.co/edit/ggt7

Solution 1:

The SDK parses your document for elements to replace with social plugins only once upon initialization.

If you add content later on, you need to call FB.XFBML.parse to have it go through the document (or parts thereof) again.


Solution 2:

I did some testing and I ended up doing a directive and using FB.XFBML.parse (), follows suit working on Plunker:

http://plnkr.co/edit/oTj3jP

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.fbComments = 'http://developers.facebook.com/docs/plugins/comments/';
});

app.directive('fbCommentBox', function() {
  function createHTML(href, numposts, colorscheme, width) {
    return '<div class="fb-comments" ' +
      'data-href="' + href + '" ' +
      'data-numposts="' + numposts + '" ' +
      'data-colorsheme="' + colorscheme + '" ' +
      'data-width="' + width + '">' +
      '</div>';
  }

  return {
    restrict: 'A',
    scope: {},
    link: function postLink(scope, elem, attrs) {
      attrs.$observe('pageHref', function(newValue) {
        var href = newValue;
        var numposts = attrs.numposts || 5;
        var colorscheme = attrs.colorscheme || 'light';
        var width = attrs.width || '100%';
        elem.html(createHTML(href, numposts, colorscheme, width));
        FB.XFBML.parse(elem[0]);
      });
    }
  };
});
