Facebook Comments Plugin not displaying in AngularJS
Question
SEE UPDATE AT BOTTOM OF THIS POST
I am trying to implement a Facebook comments box in an ng-repeat and am having issues with it displaying.
In Chrome it doesn't display until I click the refresh button, whereas in IE10 I can not get it to display at all.
My (simplified) index page:
<!doctype html>
<html lang="en" data-ng-app="eatsleepcode">
<head>
<title data-ng-bind="pageTitle"><eat-sleep-code /></title>
<meta charset="utf-8" />
<base href="/">
<link rel="stylesheet" href="/style/jquery-ui.min.css" />
<link rel="stylesheet" href="/style/bootstrap.min.css" />
<link rel="stylesheet" href="/style/bootstrap-theme.min.css" />
<link rel="stylesheet" href="/style/en-us.css" />
</head>
<body>
<div class="container-fluid">
<div class="col-lg-8 page-content" id="content" data-ng-view>
</div>
<div class="col-lg-4 page-content">
</div>
</div>
<footer id="footer">
<div class="container-fluid">
</div>
</footer>

My view:
<div class="blog-main">
<article class="blog-post" data-ng-if="article.id == post || post===NULL" data-ng-repeat="article in data.blog.article | orderBy:'createdate':true | slice:currentPage*pageSize:currentPage+1*pageSize" itemscope itemtype="http://schema.org/BlogPosting">

<span class="blog-post-meta">Posted on <time datetime="{{article.createdate | date:'yyyy-MM-dd'}}">{{article.createdate | date:'MMMM dd, yyyy h:mma'}}</time> by <span itemprop="author">{{article.author}}</span></span>
<div class="blog-post-content-wrapper">
<div class="blog-post-content" ng-bind-html="article.content.__cdata" itemprop="text">

<div data-ng-if="article.id == post">
<div class="fb-comments" data-href="http://eat-sleep-code.com/#!/blog/{{article.id}}" data-numposts="5" data-colorscheme="light" data-width="100%"></div>
<br />
<a href="/#!" class="btn btn-default btn-sm blog-button-back"><span class="glyphicon glyphicon-chevron-left blog-button-back-icon"></span> Back</a>
</div>
</article>
<div data-ng-if="numberOfPages > 1">
<button type="button" class="btn btn-default btn-sm blog-button-older" data-ng-disabled="currentPage == 0" data-ng-click="currentPage=currentPage-1"><span class="glyphicon glyphicon-chevron-left blog-button-older-icon"></span> Older Posts</button>
<button type="button" class="btn btn-default btn-sm blog-button-newer" data-ng-disabled="currentPage >= numberOfPages - 1" data-ng-click="currentPage=currentPage+1">Newer Posts <span class="glyphicon glyphicon-chevron-right blog-button-newer-icon"></span></button>
</div>
</div>
I found this issue: Facebook comment plugin Angularjs but mine appears to be different, because when I view the current elements, I see that the data-href is populated correctly:
<div class="fb-comments" data-href="http://eat-sleep-code.com/#!/blog/2" data-numposts="5" data-colorscheme="light" data-width="100%"></div>
UPDATE:
I updated the line in the view to this:
<div class="fb-comments" dyn-fb-comment-box page-href="http://eat-sleep-code.com/#!/blog/{{article.id}}" data-numposts="5" data-colorscheme="light" data-width="100%"></div>
I added the following directive, and now the comments box is displaying. However, the data-width attribute is now being ignored. The comments box is rendering at the default 550px width.
app.directive('dynFbCommentBox', 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]);
});
}
};
});

You would need to make a directive that watches the data-href attribute as suggested in the (essentially same) issue with flash in https://stackoverflow.com/a/15285102/3715815 and also in the post you are pointing to yourself with the facebook link. The reason is still the same; angular takes some time interpolate the values between the interpolation symbols and therefore the facebook sdk just "fires" on the data that is there, which essentially will be http://eat-sleep-code.com/#!/blog/ {{article.id}} because it is not a part of angular's internal loop.
There are also many other articles that deals with the issue of loading images, as the browser will try to fetch all images using the src attribute when it encounters one, also happing before the real src value has been interpolated. Therefore, there are are directives made by the core angular team such as ng-src that deals with such common usecases, but on this one you would have to do it as the post you are linking to describes.

i was trying with protocol free url for data-href attr; it didn't work; once i added http it worked - possibly that could be a cause.
