データベースからオートコンプリート

Question

こんにちは人：

<script> 
    $('#SearchBox').autocomplete({ source: '/Controller/ShowAllGames' }); 
</script> 

と私のShowAllGamesコントローラで私のオートコンプリート機能するために、次のコード：

public ActionResult AutoCompleteGames(string term) 
    { 
     var db = new gamezoneDBEntities(); 
     return Json(db.tblGames.Where(games => games.GameName.StartsWith(term)).Select(games => games.GameName), JsonRequestBehavior.AllowGet); 

    } 

Iドン自分の情報を入力するときに自分のオートコンプリートが機能しない理由を知っていますか、自分のデータベースの単語が表示されていません。また、スクリプトは以下の通りですし参照のうえれる検索ボックス：私はserachボックスとページングがうまくすべての作業を有効にちょうど私の自動補完が

が機能しない理由を知りたいき

@using (Html.BeginForm()) 
{ 
    <div id="SearchBorder"> 
    <div id="TopSearch"> 

     @Html.TextBox("DisplaySearchResults", "", new { style = "width:420px;" }) 
     <input id="SearchBox" type="submit" value="Search news archives"/> 
     </div> 
     </div> 
} 

はあなた

Answer 1

jrummellの問題以外にも、ソース引数はアクションの名前と一致しません。

<script> 
    $('#SearchBox').autocomplete({ source: '/ShowAllGames/AutoCompleteGames' }); 
</script> 

検索ボックスに入力すると404エラーが発生すると思われます。

EDIT

まあ、それはあなたが404年代を取得されていませんように私には意味をなさないが、これを試していません。アクションからパラメータstring termを削除し、機能内で

string term = this.Request.Params["term"].ToString(); 

を使用してください。正しく覚えていれば、モデルバインダーはそのパラメーターを期待どおりに設定しません。

Answer 2

1つの問題は、あなたのテキストボックスの代わりに、ボタンのオートコンプリートを作っているということです。オートコンプリートの初期化を次のように変更してください：

$('#DisplaySearchResults').autocomplete({ source: '/Controller/ShowAllGames' });
