データベースからユーザーの投稿を取得するスクリプトを作成しましたが、もうすぐです。ajaxが呼び出され、Firebugの応答で10件の投稿が表示されますが、[さらに読み込む]をクリックすると、ページに1件の投稿しか表示されません。さらに9つの結果を表示するには、以下のコードに何を追加する必要がありますか？

[{item1, item2},{item11, item12},...] のような JSON を PHP から受信し、それを反復せずに最初のグループのみを使用しています。$.getJSONの代わりに function を使用するのが最善かつ最も簡単な方法だと思います$.ajax。ここで 2 番目の例を見てください。PHP から受け取った JSON を処理するために必要なのはこれだけだと思います。
