如何基于javascript变量动态更改facebook评论插件网址？

Question

我想基于javascript变量动态更改下面的fb评论插件的data-href.我正在运行一个flash swf文件,并通过javascript函数将data-href的新链接传递给html包装器.当我这样做时,我希望fb comments插件刷新到新的data-href链接.

<div style="float: left; padding-left:5px; min-height:500px" class="fb-comments" data-href="www.example.com" data-num-posts="20" data-width="380"></div>

调用javascript函数传递注释插件的新链接:

function changeCommentsUrl(newUrl){
// should refresh fb comments plugin for the "newUrl" variable
}

Answer 1

这将加载初始注释框,脚本将在执行时清除注释div包装器并用新url替换html5注释框.然后,JS SDK将解析新框.

这项工作需要JS SDK.请参阅https://developers.facebook.com/docs/reference/javascript/

从dom操作修复xfbml渲染

<div id="comments">
<div style="float: left; padding-left:5px; min-height:500px" class="fb-comments" data-href="www.example.com" data-num-posts="20" data-width="380"></div>
</div>
<script>
function changeCommentsUrl(newUrl){
// should refresh fb comments plugin for the "newUrl" variable
document.getElementById('comments').innerHTML='';
parser=document.getElementById('comments');
parser.innerHTML='<div style="float: left; padding-left:5px; min-height:500px" class="fb-comments" data-href="'+newUrl+'" data-num-posts="20" data-width="380"></div>';
FB.XFBML.parse(parser);
}
</script>

用户解决了:

document.getElementById('comments').innerHTML='<div style="float: left; padding-left:5px; min-height:500px" class="fb-comments" data-href="'+link+'" data-num-posts="20" data-width="380"></div>'; 
FB.XFBML.parse(document.getElementById('comments'));
