Hello Friends,
I'm new to webservice's, I'm trying out autocomplete textbox using jquery. Following is code:
.aspx

<html xmlns="http://www.w3.org/1999/xhtml">
<head  runat="server">
    <title></title>
    <script src="../JQuery/JQuery.js" type="text/javascript"></script>
    <script type="text/javascript">
        function lookup(inputString) {
            if (inputString.length == 0) {
                $("#suggestions").hide();
            }
            else {
                $.ajax({
                    type: "POST",
                    url: "WebService.asmx/getClientName",
                    dataType: "json",
                    data: "{}",
                    contentType: "application/json; charset=utf-8",
                    success: function(data) {
                        if (data.length > 0) {
                            var datafromserver = data.d.split(",");
                            $("#suggestions").show();
                            $("#suggestionList").html(datafromserver); 'LINE1
                        }
                    },
                    error: function(XMLHttpRequest, textStatus, errorThrown) {
                        alert(textStatus);
                    }
                });
            }
        }
        
    </script>
    <style type="text/css">
    body{
        font-family: Helvetica;
        font-size: 13px;
        color: #000;
        }
    h3{
        margin: 0px;
        padding: 0px;
      }
    .suggestionsBox{
        position: relative;
        left: 0px;
        margin: 0px 0px 0px 0px;
        width: 200px;
        background-color: #7845DD;
        -moz-border-radius: 7px;
        -webkit-border-radius: 7px;
        border: 2px solid #000;
        color: #fff;
        }
    .suggestionList {
        margin: 0px;
        padding: 0px;
        }
    .suggestionList li {
        margin: 0px 0px 3px 0px;
        padding: 3px;
        cursor: pointer;
        }
    .suggestionList li:hover {
        background-color: #DD45CD;
        }

</style>
</head>
<body>
    <form id="form1"  runat="server">
    <div>
        <asp:TextBox ID="txtAutoComplete" runat="server">
    </div>
    <div class="suggestionsBox" id="suggestions" style="display: none;"></div>
    <div class="suggestionList" id="autoSuggestionsList"></div>
    </form>
    
</body>
</html>

When I run the page, the autocomplete dropdown is not working. Any idea where I'm going wrong?
Is there any issue at LINE1?

Thanks in advance

 //this way you cant get record from the dataBase
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 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 WebService1 : System.Web.Services.WebService
    {
        SqlConnection Con;
        SqlCommand Cmd;
        string[] items;


        [WebMethod]
        public string[] GetStateName(string prefixText)
        {
            try
            {
                Con = new SqlConnection("Your Connection string");
                Con.Open();
                Cmd = new SqlCommand("sp_getValue", Con);
                Cmd.CommandType = CommandType.StoredProcedure;
                Cmd.Parameters.AddWithValue("@prefixText", prefixText);
                SqlDataAdapter da = new SqlDataAdapter(Cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);
                items = new string[dt.Rows.Count];
                int i = 0;
                foreach (DataRow dr in dt.Rows)
                {
                    items.SetValue(dr["StateName"].ToString(), i);
                    i++;
                }
            }
            catch (Exception ex)
            {
              throw ex;
            }
            finally
            {
                Con.Close();
            }
            return items;
        }
        }
