Question

我有一个jquery示例，当我输入字母时有效，但在输入数字时不起作用：

<script>
    $(function() {
        $("#box1").autocomplete({
            url: 'test-search3.ashx?s=mrn'
        });
    });
</script>

<form>
 <input type="text" id="box1">
</form>

以下是ashx页面的代码：

<%@ WebHandler Language="VB" Class="test_search" %>
Imports System
Imports System.Web
Imports System.Data.SqlClient
Imports System.Configuration
Imports System.Text

Public Class test_search : Implements IHttpHandler

    Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
        context.Response.ContentType = "text/plain"
        Dim qString As String = context.Request.QueryString("q")
        Dim typeString As String = context.Request.QueryString("s")
        Dim sqlStr As String = ""

        Try
            Dim conn As SqlConnection = New SqlConnection
            conn.ConnectionString = ConfigurationManager.ConnectionStrings("connString").ConnectionString
            Dim cmd As SqlCommand = New SqlCommand
            If typeString = "mrn" Then               
                sqlStr = "select Pat_ID, Name=LastName + ', ' + FirstName " & _
                " from Patients p Where Active=1 " & _
                " and p.MRN like '" & qString & "%' order by lastname"
            Else
                sqlStr = "select Pat_ID, Name=LastName + ', ' + FirstName " & _
                " from Patients p Where Active=1 " & _
                " and Lower(LastName) like '" & qString & "%' order by lastname"
            End If

            cmd.CommandText = (sqlStr)
            cmd.Connection = conn
            Dim sb As StringBuilder = New StringBuilder
            conn.Open()
            Dim sdr As SqlDataReader = cmd.ExecuteReader
            'sb.Append(qString & "/" & typeString).Append(Environment.NewLine)
            While sdr.Read
                sb.Append(sdr("Name") & "|" & sdr("Pat_ID")).Append(Environment.NewLine)
            End While
            conn.Close()
            context.Response.Write(sb.ToString)
        Catch ex As Exception
            context.Response.Write("Error: " & ex.ToString)
        End Try

    End Sub

    Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
        Get
            Return False
        End Get
    End Property

End Class
