jsonというレスポンスからデータを取得しようとしています。しかし、私はエラー応答を得ています。私は一度この問題を抱えていましたが、私はPHPファイルにheader('Content-type: application/json');を追加して解決することができます。しかし、今私はそれを行う場合、私のコードを壊すのは、私はそれのHTMLコードをたくさん持っている別のファイルにファイルを含めるので、それは応答でコードをロードします。どういうわけか、そのヘッダなしでjsonの応答を得ることはできますか？コンテンツタイプが正しくないAjax JSON

どのようなエラーが発生しますか？ –
さて、それは単に 'success：function（）'の代わりに 'error：function（options）'にajaxに入っています。 – rtom
すべてのhtmlコードを変数に格納してからjson_encode変数に入れてみてください。 –
