私のコードに問題があります。現在、私はJSONデータベースからアイテムを引き出しており、ページには多くのアイテムが表示されています。私はshowProductと呼ばれるクラスを持っています。これは、ページ上でアイテムがクリックされたときに発生します。これは、項目を1つの項目に絞り込んで、名前、画像などをDIVに表示する機能を実行します。JSのページをリロードしないでください
私のコードでは、私は同じ関数をもう一度呼び出すことを試みています（showProduct）。私はそれが正しい項目でページをリロードすることを望みます。それは私がすでにこの機能を一度呼び、それをもう一度呼び出そうとしているという事実と関係していますか？以下は私のコードのおかげです。
