jsp页面是这样的:

<%
String   id=(String)request.getAttribute( "id ");
String   name=(String)request.getAttribute( "name ");
if(id!= " "&&name!= " ")
{
String   sqlStr= "insert   into   examinees   values( '343534 ', 'dukeduke ', '8888 ') ";
db.setConnection( "sun.jdbc.odbc.JdbcOdbcDriver ", "jdbc:odbc:exam ", "sa ", " ");
db.setStatement(sqlStr);
db.update();
db.disConnect();
}
%>


<script   language= "JavaScript ">
function   check()
{
if(document.form1.id.value== " ")
{
alert( "请输入考生号码 ");
document.form1.id.focus();
return   false;
}
else   if(document.form1.name.value== " ")
{
alert( "请输入考生姓名 ");
document.form1.name.focus();
return   false;
}
}
</script>
