在本帖子的底部看到更新

我正在尝试在ng-repeat中实现Facebook评论框,并且显示它有问题。

在Chrome中,在我点击刷新按钮之前它不会显示,而在IE10中我根本无法显示它。

我的(简化)索引页:

<!doctype html>
<html lang="en" data-ng-app="eatsleepcode">
    <head>
        <title data-ng-bind="pageTitle">&lt;eat-sleep-code /&gt;</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>

我的观点:

<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">
        <h2 class="blog-post-title" itemprop="headline">
            <a href="http://eat-sleep-code.com/#!/blog/{{article.id}}" title="Permalink to {{article.title.__cdata}}" itemprop="url">{{article.title.__cdata}}</a>
        </h2>
        <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">
                {{article.content.__cdata}}
            </div>
        </div>
        <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>

我发现了这个问题:Facebook comment plugin Angularjs但我的看似不同,因为当我查看当前元素时,我看到数据-href 正确填充:

<div class="fb-comments" data-href="http://eat-sleep-code.com/#!/blog/2" data-numposts="5" data-colorscheme="light" data-width="100%"></div>


更新

我将视图中的行更新为:

<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>

我添加了以下指令,现在显示了注释框。但是,现在忽略data-width属性。注释框以默认的550px宽度呈现。

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]);
            });
        }
    };
});

你需要制作一个指令来监视data-href属性,如https://stackoverflow.com/a/15285102/3715815中闪存的(基本相同)问题所示,以及你用facebook链接指向自己的帖子。原因仍然是一样的;角度花费一些时间插值插值符号之间的值,因此facebook sdk只是&#34;触发&#34;关于那里的数据,基本上是http://eat-sleep-code.com/#!/blog/ {{article.id}},因为它不是角度内部循环的一部分。

还有很多其他文章处理加载图像的问题,因为浏览器会在遇到一个图像时尝试使用src属性获取所有图像,在插入真实的src值之前也会出现问题。因此,核心角度团队(例如ng-src)有一些指令可以处理这些常见的用例,但是在这个指令上你必须按照你链接的帖子来描述。

我正在尝试使用协议免费网址进行data-href attr;它没有工作;一旦我添加http它有效 - 可能这可能是一个原因。
