AJAX呼び出しでロードされたオプション値を選択してください。不正なエラーが検出されたことを示します
国という名前のフォームに選択フィールドがあります。国が変わると、州の値を読み込む必要があります。状態をリストするためのフィールドをすでに配置しました。ajaxから値をロードしたいだけです。同様に、都市フィールドも追加する必要があります。フォームを送信するたびに、状態（ajaxによってロードされたフィールド）が 'であることを示します'違法な選択が検出されました。サイト管理者に連絡してください。 ajax呼び出しからdrupalフォームにロードしたフィールドステートの新しいオプション値を更新するにはどうすればよいですか。特定のフィールドキャッシュデータをクリアするにはどうすればよいですか？コードサンプルをすぐに提供します。
$('#edit-field-p-location-value').change(function(){
form_build_id = $('input[name=form_build_id]').val();
locationval = $(this).val();
var url = window.location.href;
var arr = url.split("/");
var result = arr[0] + "//" + arr[2];
if(locationval!= ''){
$.ajax({
type : 'POST',
url: result+"/gasf/getIPSecZone/"+locationval,
data:{datacenter:locationval},
success : function(data){
//$('#edit-field-p-ipseczone-value-wrapper').html(data);
$('#edit-field-p-ipseczone-value').html(data);
}
});
}
});
独自に記述するのではなく、組み込みの Drupal AJAX 関数を使用する必要があります。 開発者向けの例 モジュールには、コピーできる詳細な例があります。
この場合、選択ボックスに追加できます
'#validated' => 'true'
フォームまたはform_alter内。しかし、私はあなたに提案したいのですが、Drupal AJAXを使用してください。
drupal 7のフォームAPIには、["#ajax"] etcこれは、あなたが投稿したjqueryの方法ではなく、これに使用する必要があります。
以下のロジックを実装してみてください。国/都市などを取得するためにSQLクエリなどを変更する必要があります
