推荐：JScript中遍历Request表单参数集合的方法

JScript下有一个Enumerator对象可以遍历集合。根据它的文档写了以下程序，可以遍历整个Request.QueryString集合：代码如下: var params = new Enumerator(Request.QueryString); while (!params.atEnd()) { Response.Write(params.item() + : + Request.QueryString(p

代码如下:

Function GetTable(Table,Where,Order,OrderSort,curpage, pagesize,MiniJson)

'Author : nigou

'使用方法 : Response.Write GetTable(Table表名,Where条件,Order主键(必须),OrderSort(asc,desc),curpage当前页, pagesize每页条数,MiniJson是否输出为miniUI格式)

'

dim i, j ,rs

if OrderSort="" Then OrderSort="asc"

if Where="" Then Where="asc"

Set Rs=Server.CreateObject("adodb.recordset")

if curpage>1 then

TmpSql="select a.* from ( select top " & (curpage) * pagesize & " * from " & Table & " where " & where & " order by " & Order & " " & OrderSort & ") a left join ( select top " & (curpage-1) * pagesize & " * from " & Table & " where " & where & " order by " & Order & " " & OrderSort & ") b on a." & Order & "=b." & Order & " where iif(b." & Order & ",'0','1')='1'"

else

TmpSql="select a.* from ( select top " & (curpage) * pagesize & " * from " & Table & " where " & where & " order by " & Order & " " & OrderSort & ") a "

end if

if pagesize=0 Then TmpSql = "select * from " & Table

Rs.open TmpSql,conn,1,1

RealSize=Rs.recordcount

for i=0 to Rs.recordcount-1

TmpJson= TmpJson & "{"

for j=0 to Rs.fields.count-1

TmpJson= TmpJson & """" &(Rs.fields(j).name) & """ : "

TmpJson= TmpJson & """" & Rs(j) & """"

if j<Rs.fields.count-1 then TmpJson= TmpJson & " , "

next

TmpJson= TmpJson & " }"

if i<Rs.recordcount-1 then TmpJson= TmpJson & ","

TmpJson= TmpJson & vbcrlf

rs.movenext

next

Rs.close

if MiniJson=1 Then

CountSql="select count("& order &") from " & Table & " where " & where

Rs.open CountSql,Conn,1,1

Counts=Rs(0)

Rs.Close

GetTable=ToMiniUi(TmpJson,Counts)

Else

GetTable=toJson(TmpJson)

end if

Set Rs=nothing

End Function

function toJson(JsonStr)

toJson="[" & vbcrlf & JsonStr & vbcrlf & "]"

end function

Function ToMiniUi(JsonStr,total)

ToMiniUI="{"

ToMiniUI=ToMiniUI & """total"":"" " & total & """," & vbcrlf

ToMiniUI=ToMiniUI & """data"": [" & JsonStr

ToMiniUI=ToMiniUI & "]}"

End Function

PS：最后的参数是针对miniUI开发的,可以无视
