Asp中使用JQuery的AJAX提交中文乱码解决方法

<script>
    //jquery的post
    $.post
    (
        'server.asp',
        {
            Act:'DoSubmit',
            UserName:escape('黑区网络'),//进行编码
           WebSite:'www.jb51.net'
        },
        function(data)
        {
            alert(unescape(data));//对返回数据进行解码
        }
    );   
</script>

< %
Response.Charset="gb2312"
Dim UserName,WebSite
If Request.Form("Act")="DoSubmit" Then
UserName=Request.Form("UserName")
WebSite =Request.Form("WebSite")
 
'在服务器端解码
UserName=VbsUnEscape(UserName)//解码
 
'处理数据
'---省略数据处理部分
 
'数据处理后输出，先用VbsEscape()编码
Response.Write VbsEscape(UserName)
End If
%>
 
 
< %
'与javascript中的escape()等效
Function VbsEscape(str)
    dim i,s,c,a
    s=""
    For i=1 to Len(str)
        c=Mid(str,i,1)
        a=ASCW(c)
        If (a>=48 and a< =57) or (a>=65 and a< =90) or (a>=97 and a< =122) Then
            s = s & c
        ElseIf InStr("@*_+-./",c)>0 Then
            s = s & c
        ElseIf a>0 and a<16 Then
            s = s & "%0" & Hex(a)
        ElseIf a>=16 and a<256 Then
            s = s & "%" & Hex(a)
        Else
            s = s & "%u" & Hex(a)
