fcbkcomplete與ajax請求獲取數據

Question

我剛剛在我的項目中嘗試fcbkcomplete，但我有麻煩調用ajax請求將結果提取到自動完成任何人都知道如何完成它？

服務器端：

public static string tagFriendAutocomplete() 
{ 
    string Result = ""; 
    string query = "select fr.FRIEND_ID,c.[USER_NAME] from clients c inner join friends fr on c.CLIENT_ID=fr.FRIEND_ID and fr.CLIENT_ID=1 and c.[USER_NAME] like '%a%' "; 

    DataTable dt = new SQLHelper(SQLHelper.ConnectionStrings.WebSiteConnectionString).getQueryResult(query); 
    if (dt.Rows.Count > 0) 
    { 
     for (int i = 0; i < dt.Rows.Count; i++) 
     { 
      Result += dt.Rows[i]["USER_NAME"] + ","; 
     } 
    } 

    return Result; 
} 

客戶端：

$(document).ready(function() { 
      $("#select3").fcbkcomplete({ 
       //"autoCompleteFriendTag/data.txt", 
       addontab: true, 
       maxitems: 10, 
       input_min_size: 0, 
       height: 10, 
       cache: true, 
       newel: false, 
       select_all_text: "select" 
      }); 

}); 

我不知道放在哪裏了jQuery AJAX代碼的任何幫助，請我一直2天尋找一個解決方案，但可悲的是我沒有找到我的阿賈克斯代碼是：

$.ajax({ 
       type: 'POST', 
       url: 'Testautocomplete.aspx/tagFriendAutocomplete', 
       data: "{}", 
       contentType: 'application/json; charset=utf-8', 
       dataType: 'json', 
       success: function (data) { 

        return data.d.split(','); 

       }, 
       error: function (xhr) { 
        alert("responseText: " + xhr.responseText); 
       } 
      });

試試這個;

$(document).ready(function() { 
     $("#select3").fcbkcomplete({ 
      json_url: 'Testautocomplete.aspx/tagFriendAutocomplete', 
      addontab: true, 
      maxitems: 10, 
      input_min_size: 0, 
      height: 10, 
      cache: true, 
      newel: false, 
      select_all_text: "select" 
     }); 
}); 

還有很重要的一點，你必須通過其序列來發送數據json格式。

你的代碼應該看起來像這樣;

public static string tagFriendAutocomplete() 
{ 

    Dictionary<> jsonResult= new Dictionary<>(); 
    string query = "select fr.FRIEND_ID,c.[USER_NAME] from clients c inner join friends fr   on c.CLIENT_ID=fr.FRIEND_ID and fr.CLIENT_ID=1 and c.[USER_NAME] like '%a%' "; 

    DataTable dt = new SQLHelper(SQLHelper.ConnectionStrings.WebSiteConnectionString).getQueryResult(query); 
    if (dt.Rows.Count > 0) 
    { 
    for (int i = 0; i < dt.Rows.Count; i++) 
     { 
     jsonResult.Add(dt.Rows[i]["USER_NAME"], i); 
     } 
    } 

    var result = from r in jsonResult select new 
    { 
     key = r.Key, 
     value = r.Value 
    }; 

    JavaScriptSerializer ser = new JavaScriptSerializer(); 
    context.Response.Write(ser.Serialize(result)); 
}
