JavaScriptでの非同期通信実装①

Posted at

非同期通信を実装

まず結論はrespond_toを用います。
以下、定義です。

respond_to do |format|
  format.html { render ... } 
  format.json { render ... } 
end

html形式だとそのまま該当するビューを返して終わりですが
JSONを返す場合は下の書き方で指定してあげましょう。
非同期通信を施したい箇所をrender以下に記述してください。
なお、記述箇所はやり方にもよりますが
コントローラーのcreateアクション内に記述します。

次は肝となるajaxについて記述します。
