私はこれを何日も機能させようとしてきましたが、それは次々と起こるようです。最初に、JSON 文字列で ASP.NET の日付をグリッドに戻す際に問題が発生したことを突き止めました。私は現在、JSON.NET を使用しており、日付が本来あるべき姿に戻ってきています。これが私のコード、返されたjson文字列、およびjqGridコードです:(長くて申し訳ありませんが、それが私を台無しにしていた部分である場合に備えて、何も残したくありませんでした)! 基本的に、私は addJSONData を試みる ajax 呼び出しの成功メソッドで継続的に立ち往生しています....現在、次のような Firebug からのエラーが発生しています: records:5,[{"ROWID":1,"...rName":"BCC","SubmitterID":"BCC4010","Su

どんな助けでも大歓迎です!私はこのプラグインをとても使いたいのですが、それを機能させようとして絶対に狂っています!


前もって感謝します、ブリアナ:-)

JSON を使用して jqGrid を ASP.NET で動作させるために多くの時間を費やしました。動作するようになったので、共有したいと思います。他の人のために時間を節約したいと考えています。

ここで答えを見つけました。これは、これを機能させる方法が他にないと言っているわけではありません (確かにあると思います)。しかし、これは間違いなく機能します。

私にとって違いを生んだことを要約すると:

  • jqGrid の設定で「datatype: function() {」を使用し、「datatype: json」を使用しない。関数は "$.ajax(" を使用してサービスを呼び出します。Fiddler を見ると、ブラウザーに返されるデータが (XML でラップされた JSON ではなく) 純粋な JSON に変更されました。
  • データ クラスを返す Web サービスを使用する (jqGrid が期待するスキーマで)。最初に JSON.NET を使用してみましたが、何らかの理由で、文字列内のすべての引用符に対してメッセージが \ でエスケープされることが (Fiddler で再び) 示されました。JSON.NET を動作させることができると確信しています。しかし、それがなくても同じように機能します。

そのリストの識別子がありません:

return_value = {
    total:1,
    page:1,
    records:5,
    [{  .. some X12 messages  ..}]
}

実際、tvanfossonは「行」識別子の要件について優れた点を指摘しています。私はjMSAjaxに慣れていないので、私のコメントは無効である可能性があります。承知いたしましたら幸いです。


戻り値の型が文字列であるという単純なものでしょうか? つまり、応答が評価されると、json オブジェクトではなくカプセル化された文字列になります。

私自身も似たような場所にいたことがあります。オプションは、予想されるjqGrid応答を表すビジネスオブジェクトを作成し、文字列ではなくオブジェクトを返すか(ASP.NETはJSONとしてシリアル化します!)、またはjqGridを変更して応答を2回評価する(乱雑)のいずれかであることがわかりました。 .

行プロパティ識別子を追加しているようには見えません。変更してみてください:

json.Append(JsonConvert.SerializeObject(objPageCollection))

json.Append("rows: " + JsonConvert.SerializeObject(objPageCollection))

これがうまくいかない場合は、問題を単純化することをお勧めします。たとえば、データを 1 行に減らし、より単純なデータで機能するかどうかを確認してから、徐々にデータを追加して戻します。
