従来のBloggerにあったコメント機能には、特定のコメントに対して返信することができませんでした

しかし、昨日のアップデートでコメントシステムがアップデートされたことにより、コメントをスレッド形式で表示することが可能になりました。

Engage with your readers through threaded commenting - Blogger Buzz

http://buzz.blogger.com/2012/01/engage-with-your-readers-through.html

早速テストしてみようと思いこのブログのコメント欄を見てみましたが"Reply"や"返信"という項目が見つかりませんでした。

色々調べてみると、テンプレートの修正ブログの設定の変更が必要があるようです。

テンプレートの修正

純正のテンプレートを利用している方は恐らくそのままでも表示することが可能ですが、このブログのように独自のテンプレートを利用している場合は、コードの追加と修正が必要になります。

これから追加するコードは全てBloggerの標準テンプレートからの抜粋になります。詳しい構文などを知りたい方は、そちらを参照してください。

カスタムテンプレートを利用している方は必ず既存のテンプレートのバックアップを取ってから作業することをお勧めします。

では、まず最初に以下のコードを"<b:widget id='Blog1' locked='true' title='ブログの投稿' type='Blog'></b:widget>"の中に挿入してください。意味が分からない方は"<b:widget id='Blog1' ...>"の直後でOKです。

<b:includable id='threaded_comments' var='post'>
  <b:include name='threaded_comment_css'/>

  <div class='comments' id='comments'>
    <a name='comments'/>
    <h4>

    </h4>

    <div class='comments-content'>

コードが挿入できたら次はテンプレートから"<b:includable id='main' var='top'>"という文字列を探し、その下にある、"<b:include data='post' name='comments'/>"を以下のコードに置き換えます。

<b:if cond='data:blog.pageType == &quot;static_page&quot;'>
  <b:if cond='data:post.showThreadedComments'>
    <b:include data='post' name='threaded_comments'/>
  <b:else/>

    <b:include data='post' name='threaded_comments'/>
  <b:else/>
    <b:include data='post' name='comments'/>
  </b:if>
</b:if>

以上でテンプレートの修正は終わりです。

ブログの設定の変更

ブログの設定画面で以下の2点を変更します。

  1. 設定 > 投稿とコメント > コメント > コメントの場所 : 埋め込み
