jQuery datepicker を使用した JSF (Mojarra) v2.1.11、Primefaces v3.4.2、Java 6 Web アプリケーションがあります。次のようなセレクターを使用しています。
$('#form1\\:dp').datepicker({showOn: 'button', buttonText: "Choose"});
これにより、ユーザーはボタンをクリックして日付ピッカーを呼び出すことができます。私が抱えている問題は、ユーザーがフォームを送信した後に「ボタン」が消えることです。どうやら、「ボタン」は、ページが最初に読み込まれたときに一度だけ読み込まれます。送信/ポストバック間で JQuery 日付ピッカーの「ボタン」を永続化する方法(ベスト プラクティスとは)を知りたいです。
