我希望在我的网格中向 textvox 添加自动完成功能，但是，我无法从脚本中调用文本框。
HTML代码是
<head runat="server">
<title></title>
<link href="css/jquery.autocomplete.css" rel="stylesheet" type="text/css" />
<script src="scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="scripts/jquery.autocomplete.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="grdUserTrans" CellSpacing="1" runat="server"
Width="100%">
<Columns>
<asp:BoundField HeaderText="" DataField="ID" SortExpression="ID"
ItemStyle-HorizontalAlign="Center"></asp:BoundField>
<asp:BoundField HeaderText="Register Number" DataField="REGNO"
ItemStyle-HorizontalAlign="Left"></asp:BoundField>
<asp:BoundField HeaderText="Name" DataField="USERNAME"
ItemStyle-HorizontalAlign="Left"></asp:BoundField>
<asp:TemplateField HeaderText="Stop Name" ControlStyle-CssClass="radionobrdr"
ItemStyle-VerticalAlign="Top" HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Center">
<ItemTemplate><asp:TextBox ID="txtClass" runat="server" CssClass="TextBox">
</asp:TextBox></ItemTemplate>
</asp:TemplateField></Columns></asp:GridView>
</div>
</form>
</body>
</html>
JS代码是
<script type="text/javascript">
$(document).ready(function() {
$("#<%=grdUserTrans.ClientID%>").find(".TextBox").autocomplete('Search_CS.ashx');
});
</script>
Search_CS 文件是
using System;
using System.Web;
using System.Data.SqlClient;
using System.Configuration;
using System.Text;
using System.Collections.Generic;
using System.Web.Services;
using System.Web.Script.Services;
using System.Collections.Specialized;
using System.Data;
public class Search_CS : IHttpHandler {
public void ProcessRequest (HttpContext context) {
string prefixText = context.Request.QueryString["q"];
using (SqlConnection conn = new SqlConnection())
{
conn.ConnectionString =
ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "SELECT KSM_STOP_NAME FROM KSL_STOP_MST WHERE
KSM_STOP_NAME LIKE '%" + prefixText + "%'";
cmd.Connection = conn;
StringBuilder sb = new StringBuilder();
conn.Open();
using (SqlDataReader sdr = cmd.ExecuteReader())
{
while (sdr.Read())
{
sb.Append(sdr["KSM_STOP_NAME"])
.Append(Environment.NewLine);
}
}
conn.Close();
context.Response.Write(sb.ToString());
}
}
}
public bool IsReusable {
get {
return false;
}
}
}
连接字符串是
<connectionStrings>
<add name="constr" connectionString="Data Source=KACPER-SERVER;Initial
Catalog=KED_MACAULAY;Integrated Security=false;uid=KACPER_SQL;pwd=KACPER_SQL123;
pooling=true;connect timeout=900;max pool size=200"/>
</connectionStrings>
在此先感谢您的帮助。
