ASP 使用jqGrid实现读写删的代码(json)

ttx9n

因为有了比较成型的CMS，一直没有舍弃ASP，一直想用.net重写一下，是后话了。 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：
复制代码 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) &","
Next
'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
next
' 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:
<!--#include file="conn.asp" -->
<!--#include file="json.asp" -->
<%
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
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " = " & strFieldData
Else
strWhere = strWhere & " = '" & strFieldData & "'"
End If
Case "ne": 'Not Equal
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " <> " & strFieldData
Else
strWhere = strWhere & " <> '"& strFieldData &"'"
End If
Case "lt": 'Less Than
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " <" & strFieldData
Else
strWhere = strWhere & " <'"& strFieldData &"'"
End If
Case "le": 'Less Or Equal
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " <= " & strFieldData
Else
strWhere = strWhere & " <= '"& strFieldData &"'"
End If
Case "gt": 'Greater Than
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " > " & strFieldData
Else
strWhere = strWhere & " > '"& strFieldData &"'"
End If
Case "ge": 'Greater Or Equal
If(IsNumeric(strFieldData)) Then
strWhere = strWhere & " >= " & strFieldData
Else
strWhere = strWhere & " >= '"& strFieldData &"'"
End If
Case "ew" : 'End With
strWhere = strWhere & " LIKE '%" & strFieldData & "'"
Case "cn" : 'Contains
strWhere = strWhere & " LIKE '%" & strFieldData & "%'"
End Select
End if
End If
server.ScriptTimeout=9000
dim a
set a=new JSONClass
a.Sqlstring="Select id,Title,NickName,Pwd,LastLoginTime From Admin"&strWhere&" "&"order by "& sidx & " " & sord
a.dbconnection=conn
response.Write(a.GetJSon())
conn.close()
set conn = nothing
%>

里面把搜索的代码涵盖了。这样基本实现了读，至于jqGrid中的editurl的文件，我们称其edit.asp，代码如下：
复制代码 代码如下:
<%Option Explicit%>
<!--#include file="config.asp"-->
<%
Dim strOper, strID, strNickName, strTitle, strPwd
strOper = Request("oper")
strID = Replace(Request("Id"),"'","''")
strTitle = Replace(Request("Title"),"'","''")
strNickName = Replace(Request("NickName"),"'","''")
strPwd = Replace(Request("Pwd"),"'","''")
Select Case strOper
Case "add": 'Add Record
strSQL = "Insert Into Admin (Title, NickName, Pwd,LastLoginTime) Values('"&strTitle&"', '"&strNickName&"', '"&strPwd&"',Now()) "
Case "edit": 'Edit Record
strSQL = "Update Admin Set Title = '"&strTitle&"', NickName = '"&strNickName&"', Pwd = '"&strPwd&"' Where id = "&strID
Case "del": 'Delete Record
strSQL = "Delete From Admin Where id = "&strID
End Select
'response.Write strSQL
Dim strSQL,rs
Call OpenDB()
Set rs = Conn.Execute(strSQL)
Call CloseDB()
%>

这是前台index.html代码
