我有一個自動完成擴展器的文本框顯示記錄作爲從數據庫中的列表,但我在點擊texbox並開始打字什麼都不開心。我的HTML代碼ajax自動完成擴展器不工作
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="TextBox1_AutoCompleteExtender" runat="server"
Enabled="True" TargetControlID="TextBox1" ServicePath="~/WebService.asmx"
ServiceMethod="GetCompletionList"
MinimumPrefixLength="2"
CompletionInterval="1000"
EnableCaching="true"
CompletionSetCount="20"
DelimiterCharacters=";, :"
ShowOnlyCurrentWordInCompletionListItem="true" >
</asp:AutoCompleteExtender>
而且我的web服務是
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using MySql.Data.MySqlClient;
using System.Configuration;
/// <summary>
/// Summary description for WebService

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
public WebService() {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public static List<string> GetCompletionList(string prefixText, int count)
{
MySqlConnection con = new MySqlConnection(ConfigurationManager.AppSettings["cn"]);
if (con.State == ConnectionState.Closed)
con.Open();
MySqlCommand cmd = new MySqlCommand("SELECT gotra FROM tbgotra WHERE gotra LIKE '%" + prefixText + "%'",con);
List<string> k = new List<string>();
using (MySqlDataReader sdr = cmd.ExecuteReader())
{
while (sdr.Read())
{
k.Add(sdr["gotra"].ToString());
}
}
con.Close();
return k;
}
}
你可以把database.asmx代碼嗎? –
我正在通過我的服務方法調用數據庫中的對象列表。這是上面給出的。 –
IM對不起,我的意思是Webservice.asmx文件,只是想確保它是正確的。 –
