Facebook评论框插件 [英] Facebook comment box plugin

问题描述

我正在使用Facebook评论框插件:

I am using Facebook comment box plugin:

<fb:comments href="${myPageUrl}" num_posts="20" width="630"></fb:comments>

一切正常.问题是我想将发布的评论存储到我的数据库中.有什么方法可以获取张贴在评论框上的文本.

Every thing is working fine. The problem is that I want to store the comment posted into my database. Is there any way to fetch the text posted on the comment box.

我正在使用以下js捕获comment-create事件.

I am using the following js to catch comment-create event.

FB.Event.subscribe('comment.create', function(response) {        
        alert(response.commentID)
});

我从中得到一些commentId，但我不知道如何获取在特定comment-create事件上发布的确切评论.

I'm getting some commentId from this but I don't know how to fetch the exact comment posted on a particular comment-create event.

推荐答案

Coomie:实际上，每当发表评论时，我都会通过'comment.create'捕获事件.我能够赶上该事件，但我想知道如何在该特定事件上发布评论(文本).类似于event.text或event.comment，但未找到直接方法

Coomie: Actually whenever a comment is posted, I catch the event thru 'comment.create'. I was able to catch the event but I was wondering how to get the comment(text) posted at that particular event. Like event.text or event.comment but there was no direct method found

因此，现在我用fql进行操作.这有点类似于您的示例.首先检索整个列表，然后选择顶部列表. 我的示例代码如下:

So, now I am manipulating it with fql. Which is somewhat similar to you example. First retrieving the whole list and then selecting the top one. My sample code is below:

FB.Event.subscribe('comment.create', function(response) {
      FB.api({
        method: 'fql.query',
        query: "SELECT post_fbid, fromid, object_id, text, time from comment WHERE  object_id in (select comments_fbid from link_stat where url ='${PageUrl}') order by time desc limit 1"
      },
      function(response) {
        var feed = response[0];          
        alert(feed.text)
      });
});  

所以这种方法给我的结果与我想要的完全一样.

So this method is giving me exactly the same result I want.
