Struts 1.x の検証中に問題が発生しました。Ajax 呼び出しで JSP ページを開いています。この JSP ページ (開いたポップアップ) で、ユーザー タイトルが必要などの検証を行いたい場合、フォームを送信するときに、必要なアクション クラス メソッドに詳細を直接送信します。送信中、私は Ajax 送信を使用していません。Ajax submit も試してみましたが、うまくいきませんでした。以下のコードは、私のアクション クラス メソッドと JSP ページです。

the required ajax call for calling this page is in parent class and the code for this is ........
function displayNotificationForm(){
var basePath='<%=basePath%>';
j("#notificationFormDetails").html(waitImage);
j('#notificationFormDetails').dialog('open');
j('#notificationFormDetails').dialog('option', 'title', 'Add Home Page Announcement');
j.ajax({
type : "GET",
url : "notifications.do?processName=displayNotificationsFormDetails",
success : function(data) {
j("#notificationFormDetails").html(data);
},
error : function(jqXHR, textStatus) {
alert("error" + textStatus);
j("#notificationFormDetails").dialog('close');
}
});
