求三级联动中的传递值
本帖最后由 x04294940191 于 2014-01-04 13:06:58 编辑下面是一个直接通过access数据库实现学校、班级到姓名的三级联动选择表单代码，经过本地测试通过。我还有一个app.asp文件，运行时需要加载这个三级联动表单中的学校、班级和姓名的值，这个值是什么(我以为是class1、class2和class3，结果不对）？给写一下。app.asp怎样获取这三个值？给写下。谢谢！

[解决办法]
app.asp可以这样获取这三个值

dim class1,class2,class3
class1=request.form("classid1")
class2=request.form("class2")
如此，，，下面提保存语句。
