- 我发个经典的,建议你去文库找下<td><input type="button" onclick="javascript:document.form1.action='update.asp?rowcount=<%=i%>&pid=<%=rs(1)%>&pcount=<%=rs(3)%>';document.form1.submit();"value="确认修改"></td>改为<td><input type="button" onclick="javascript:document.form1.action='update.asp?id=<%=rs("Id")%>&rowcount=<%=i%>';document.form1.submit();"value="确认修改"></td><%'这里需要注意在上个页面,有个i值,在这里就用到了,你要指明修改的是哪一行记录......response.redirect("mycar.asp")'执行完之后重新跳转到mycar.asp%> 改为<%'只需商品id和修改后的数量值dim idid=request.querystring("id")pcount=request.querystring("pcount")sql="update buy set pcount ='"&pcount&"' where Id="&idconn.execute sqlconn.closeset conn=nothingresponse.redirect("mycar.asp")'执行完之后重新跳转到mycar.asp%>
