jqGrid是一个优秀的基于jQuery的DataGrid框架，想必大伙儿也不陌生，网上基于ASP的资料很少，我提供一个，数据格式是json的：

一个针对jqGrid的json类：这段代码似乎是由官网论坛的一些PHP中转化而来，我们存为json.asp，代码贴一下：

代码如下:

response.Charset="utf-8"

'---------------------------------------

' JSONClass类

' 将Select语句的执行结果转换成JSON

'------------------------------------------

Class JSONClass

' 定义类属性，默认为Private

Dim SqlString ' 用于设置Select

Dim JSON ' 返回的JSON对象的名称

Dim DBConnection ' 连接到数据库的Connection对象

' 可以外部调用的公共方法

Public Function GetJSON ()

dim Rs

dim returnStr

dim i

dim oneRecord

' 获取数据

Set Rs= Server.CreateObject("ADODB.Recordset")

Rs.open SqlString,DBConnection,1,1

if page<>"" then

epage=cint(page)

if epage<1 then epage=1

if epage>rs.pagecount then epage=rs.pagecount

else

epage=1

end if

rs.pagesize = rows

rs.absolutepage = epage

' 生成JSON字符串

if Rs.eof=false and Rs.Bof=false then

returnStr="{ total: "& rs.pagecount &", page: "& page &", records: "& rs.recordcount &", rows:["

for j=0 to rs.pagesize-1

if rs.bof or rs.eof then exit for

' -------

'oneRecord = "{id:" & chr(34) &Rs.Fields(0).Value&chr(34)&",cell:["& chr(34) &Rs.Fields(0).Value&chr(34)&","

oneRecord = "{id:" & chr(34) &Rs.Fields(0).Value&chr(34)&",cell:["& chr(34) &Rs.Fields(0).Value&chr(34)&","

for i=1 to Rs.Fields.Count -1

'oneRecord=oneRecord & chr(34) &Rs.Fields(i).Name&chr(34)&":"

oneRecord=oneRecord & chr(34) &Rs.Fields(i).Value&chr(34) &","

'去除记录最后一个字段后的","

oneRecord=left(oneRecord,InStrRev(oneRecord,",")-1)

oneRecord=oneRecord & "]},"

'------------

returnStr=returnStr & oneRecord

Rs.MoveNext

' 去除所有记录数组后的","

returnStr=left(returnStr,InStrRev(returnStr,",")-1)

returnStr=returnStr & "]}"

end if

Rs.close

set Rs=Nothing

GetJSON=returnStr

End Function

'私用方法，在类中使用

Private Function check()

End Function

End Class

2、制作显示数据的asp文件，如：list.asp，代码如下

复制代码代码如下:

dim page,rows,sidx,sord

page = request.QueryString("page") 'page

rows = request.QueryString("rows") 'pagesize

sidx = request.QueryString("sidx") 'order by ??

sord = request.QueryString("sord")

if page="" then page = 1 end if

if rows = "" then rows = 10 end if

if sidx = "" then sidx = "id" end if

if sord = "" then sord ="asc" end if

Dim strSearchOn, strField, strFieldData, strSearchOper, strWhere

strSearchOn = Request("_search")

If (strSearchOn = "true") Then

strField = Request("searchField")

If (strField = "id" Or strField = "Title" Or strField = "NickName") Then

strFieldData = Request("searchString")

strSearchOper = Request("searchOper")

'construct where

strWhere = " Where " & strField

Select Case strSearchOper

Case "bw" : 'Begin With

strFieldData = strFieldData & "%"

strWhere = strWhere & " LIKE '" & strFieldData & "'"

Case "eq" : 'Equal
