Step 1.先準備要查詢的功能網頁，資料表不變(不知道是什麼看前篇)，此網頁我叫它getData2.aspx，一樣前端就一行程式碼，以下是後端程式碼，跟前篇的一樣，但只改Select指令。
Imports System.Data
Imports System.Data.SqlClient
Imports Newtonsoft.Json
Imports UControls.cswfunclass
Partial Class getData2
Inherits System.Web.UI.Page
Dim str_sql As String = String.Empty
Private Sub getData_Load(sender As Object, e As EventArgs) Handles Me.Load
'進到getData.aspx最好作個身分驗證，免得重要資訊外流
If Not Page.IsPostBack Then
'第一次進入
Dim str_rdata As StringBuilder = Nothing
If (Not Request("k") Is Nothing) Then
If Request("k").ToString = "1" Then
Dim str_query As String = String.Empty
If (Not Request("query") Is Nothing) Then
str_query = Request("query").ToString
End If
str_rdata = New StringBuilder()
Dim def_ds As New DataSet()
str_sql = "select cname as f1,id_no as f2,address1 as addr,email as mail from test_member where cname like @cname+'%'"
Using conn As New SqlConnection("Server=127.0.0.1;uid=test;pwd=test;Database=test1")
Using command As SqlCommand = New SqlCommand(str_sql, conn)
'避免 SQL Injection（資料隱碼）攻擊
If command.Parameters.Contains("@cname") Then
command.Parameters("@cname").Value = str_query
Else
command.Parameters.AddWithValue("@cname", str_query) '讓ADO.NET自行判斷型別轉換
End If
Using da As New SqlDataAdapter()
da.SelectCommand = command
da.Fill(def_ds)
End Using
End Using
End Using
str_rdata.Append(JsonConvert.SerializeObject(def_ds.Tables(0), Formatting.Indented))
Response.Write(str_rdata.ToString)
def_ds.Clear() : def_ds.Dispose()
Else
Response.Write("[]")
End If
Else
Response.Write("[]")
End If
End If
End Sub
End Class

待會我將帶出f1,f2,addr,mail資料，顯示到我要的介面上
Step 2.在新增一個aspx網頁，命名為：test_bootcomplete2
Step 3.將jquery.bootcomplete.js程式碼複製一份到test_bootcomplete2.aspx網頁中，沒有再額外建立js檔，如下：
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test_bootcomplete2.aspx.vb" Inherits="test_bootcomplete2" %>

說明紅色的部分
bootcomplete_new1：我將原本的套件bootcomplete，重新修改它的名子為bootcomplete_new1。
mainDBField、otherFieldID、arrFieldID、arrDBField：這幾個參數是我額外自己加上去的，mainDBField設定主要的欄位也就是f1要填回原本的TextBox欄位、otherFieldID是否有其他的欄位要填入資料、arrFieldID其他的欄位ID名稱、arrDBField其他資料庫資料表的欄位名稱也就是f2,addr,mail；arrFieldID與arrDBField參數必須要一致，資料才能順利填到我們要的位置。
以上我有將一些說明寫在註解裡，也有把一些原作者的語法註解掉，可能原作者還在開發或修改階段，所以不清楚他的用意，以上如有錯誤請指正，謝謝。
