具体看看代码吧，比较容易说：
<table width= "100% " border= "0 " cellspacing= "0 " cellpadding= "0 ">
<%if request( "cname ") <> " " and request( "sname ") <> " " then%>
<%sql_sl= "select distinct Order_No,OrderSuffix,SO_DelTerms,SO_PayTerms,SO_Value,SO_M3,Margin from SupplierOrderRegister where Customer_N= ' "&request( "cname ")& " ' and Supplier_Name= ' "&request( "sname ")& " ' order by SO_DelTerms "
set rs_sl=server.CreateObject( "adodb.recordset ")
rs_sl.open sql_sl,conn,3,1
acc_acc=rs_sl.recordcount
%>
<input name= "acc " type= "hidden " value= " <%=response.Write(acc_acc)%> ">
<%i=1
do while not rs_sl.eof%>
<tr>
<td width= "14% " align= "center "> <%=rs_sl( "Order_No ")%> <%=rs_sl( "OrderSuffix ")%> </td>
<input name= "Order_No <%=i%> " type= "hidden " value= " <%=rs_sl( "Order_No ")%> " />
<input name= "Suffix <%=i%> " type= "hidden " value= " <%=rs_sl( "OrderSuffix ")%> " />
<td width= "17% " align= "center "> <%=rs_sl( "SO_DelTerms ")%> </td>
<input name= "DelTerms <%=i%> " type= "hidden " value= " <%=rs_sl( "SO_DelTerms ")%> " />
<td width= "17% " align= "center "> <%=rs_sl( "SO_PayTerms ")%> </td>
<input name= "PayTerms <%=i%> " type= "hidden " value= " <%=rs_sl( "SO_PayTerms ")%> " />
<td width= "14% " align= "center "> <%=rs_sl( "SO_Value ")%> </td>
<td width= "14% " align= "center "> <%=rs_sl( "SO_M3 ")%> </td>
<td width= "14% " align= "center "> <%=rs_sl( "Margin ")%> </td>
<td width= "10% " align= "center "> <label>
<input type= "checkbox " name= "choosebox <%=i%> " value= "true " />
</label> </td>
</tr>
<%rs_sl.movenext
i=i+1
loop
%>
<%end if%>
<tr>
<td height= "20 " colspan= "7 " align= "center "> </td>
</tr>
<tr>
<td colspan= "7 " align= "center "> </td>
</tr>

请问一下怎么实现2个功能：
一：计算被选中的复选框的数量。
二：判断所有被选中的复选框所对应的DelTerms <%=i%> 和PayTerms <%=i%> 是否都一样。如果不一样，弹出框框取消。
请问一下这2个功能怎么实现呢？用javascript也可以。
------解决方案--------------------
所有复选框用相同的名字
将：
<input type= "checkbox " name= "choosebox <%=i%> " value= "true " />
改为：
<input type= "checkbox " name= "choosebox value= <%=i%> >
