有关ASP和JS相结合的问题请教各位大哥

首先我讲一下这个问题的情况背景吧:我做了一个计算器，是二手车评估的，因为JS不大熟，所以计算都是直接写VBSCRIPT脚本的，我想让用户输入现车价格和选择了入户时间之后就按公式进行计算，计算之后弹出一个计算出来二手车价值的对话框，但是，弹出的框之后，本个页面就变白，然后点击确定之后在跳转到本页面，这样很不好看，我就想对话框出来并不影响整个页面的显示，我的VB脚本是这样的:
<%
if request("submit")<>"" then
dim subyear,submonths,zj,results,pay
zj = 0
pay = request.Form("pay")
years = request.Form("years")
months = request.Form("months")
subyear = year(now())-years
submonth = month(now())-months
'response.Write(pay&"<br>")
'response.Write(years&"<br>")
'response.Write(request("submit"))
if submonth > 0 then
subyear = subyear + 1
else
subyear = subyear
end if
select case subyear
case 1
zj = 0.11
case 2
zj = 0.22
case 3
zj = 0.33
case 4
zj = 0.43
case 5
zj = 0.53
case 6
zj = 0.63
case 7
zj = 0.73
case 8
zj = 0.82
case 9
zj = 0.91
case else
zj = 1
end select
results = pay*(0.15+0.85*(1-zj))
response.write "<script language='javascript'>" & chr(13)
response.write "alert('"&results&" 万');" & Chr(13)
response.write "</script>" & Chr(13)
end if
%>
输入框表单代码为:<form name="form1" method="post" action="">
<table width="154" border="1" cellspacing="0" cellpadding="0" bordercolordark="#FFFFFF" bordercolorlight="#FFCC99">
<tr>
<td><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr bgcolor="#FFCC99">
<td height="20" colspan="2" class="style9"><div align="center">[二手价格评估]</div></td>
</tr>
<tr bgcolor="F3F3F3">
<td width="40%" valign="middle"><span class="style11">现售价:</span></td>
<td width="60%" height="20" valign="bottom"><span class="style11">
<input name="pay" type="text" id="pay" size="10">万 </span></td>
</tr>
<tr bgcolor="F3F3F3">
<td height="20"><span class="style11">入户时间:</span></td>
<td><span class="style11">
<select name="years" id="years">
<option value="请选择">请选择</option>
<%for i = 1990 to 2005%>
<option value="<%=trim(i)%>"><%=trim(i)%></option>
<%next%>
</select>
年 </span></td>
</tr>
<tr bgcolor="F3F3F3">
<td height="20"><span class="style11"></span></td>
<td><span class="style11">
<select name="months" id="months">
<option value="请选择">请选择</option>
<%for l = 1 to 12%>
<option value="<%=trim(l)%>"><%=trim(l)%></option>
<%next%>
</select>
月 </span></td>
</tr>
<tr valign="bottom" bgcolor="F3F3F3">
<td height="35" colspan="2"><div align="center">
<input type="image" name="Submit" value="计算" onclick="result()" src="bgimg/js.gif"> </div></td>
</tr>
</table></td>
</tr>
</table>
</form>

看看哪位大哥能帮个忙实现这个功能，就是不能影响页面的感观~或者可以帮忙写一个JS含数的话那更好，在线等候，谢谢拉
