アプリケーションでいくつかの問題が発生しています。コントローラーから別のページに投稿される登録フォームがあります。このページには、登録フォームからのクエリの結果が表示されます。結果ページでレコードを選択すると、データが登録ページに返されます。ユーザーは、返されたレコードを更新するか、クエリを再度実行できる必要があります。
私が抱えている問題は、ユーザーが登録フォームにいて、結果ページに投稿されたクエリを実行すると、結果ページが表示されますが、URL は変更されません。登録 URL はhttp://localhost:8084/crimeTrack/citizen_registration.htm
、クエリ ボタンをクリックして結果ページに投稿されたときですhttp://localhost:8084/crimeTrack/citizen_registration.htm
。結果ページ (複数のレコードがある) でレコードがクリック/選択されたときの URL のままです。ユーザーは、選択されたレコードと共に登録ページに戻されます。ユーザーが更新またはクエリを再度実行するように表示されます。URL はhttp://localhost:8084/crimeTrack/getCitizen/1985121244.htm
であり、ユーザーは登録ページにいます。
[クエリ/更新] をもう一度クリックすると、HTTP 400 エラーが発生し、URL が読み取らhttp://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm/
れますが、これはコントローラーで有効な URL マッピングではありません。http://localhost:8084/crimeTrack/citizen_registration.htm登録ページがリクエストされたときのURLであるべきだと思います 。結果ページからの POST によってユーザーが登録ページに戻るタイミングがわかりません。URL は http://localhost:8084/crimeTrack/getCitizen/1985121244.htm
、添付の番号が市民番号である必要があります。以下は私のコードです。これらの呼び出しを正しく行っているかどうかわかりません。得られた結果の説明と、発生した問題の解決策が必要です。
ページはjqueryを使用して送信されます。
これは登録ページの例であり、他のすべてのページは同じパターンに従います
