方法一（使用MSScriptControl.ScriptControl）：
<%
Dim sc4Json,arr0,json
InitScriptControl
json="{""name"":""123"",""content"":[{""id"":""1""},{""id"":""2""}]}"
Set jsonobj=getJSONObject(json)
'方法一
getJSArrayItem arr0,jsonobj.content,0
response.write jsonobj.name&"<br/>"&arr0.id&"<br/>"
'方法二
response.write sc4Json.Eval("jsonObject.name")&"<br/>"
response.write sc4Json.Eval("jsonObject.content[1].id")
Sub InitScriptControl
Set sc4Json = Server.CreateObject("MSScriptControl.ScriptControl")
sc4Json.Language = "JavaScript"
sc4Json.AddCode "var itemTemp=null;function getJSArray(arr, index){itemTemp=arr[index];}"
End Sub
Function getJSONObject( strJSON )
sc4Json.AddCode "var jsonObject = " & strJSON
Set getJSONObject = sc4Json.CodeObject.jsonObject
End Function
Sub getJSArrayItem( objDest, objJSArray, index )
On Error Resume Next
sc4Json.Run "getJSArray",objJSArray, index
Set objDest = sc4Json.CodeObject.itemTemp
If Err.number=0 Then Exit Sub End If
objDest = sc4Json.CodeObject.itemTemp
End Sub%>方法二：

Set sc4Json = Server.CreateObject(“MSScriptControl.ScriptControl”)
sc4Json.Language = “JavaScript”
sc4Json.AddCode “var itemTemp=null;function getJSArray(arr, index){itemTemp=arr[index];}”

End Sub
Dim strTest

Dim objTest
Call InitScriptControl

%>
<%=objTest.name%& gt;的邮件地址是<%=sc4Json.eval_r(“jsonObject.email[0]“)%><BR>共有邮件地址& lt;%=objTest.email.length%>个<BR>
