{
Connection con=null;
ResultSet rs=null;
Statement stmt=null;
String nam=request.getParameter("textfield");
Class.forName("com.mysql.jdbc.Driver");
con = java.sql.DriverManager.getConnection("jdbc:mysql:///name",
"root","");
stmt= con.createStatement();
rs=stmt.executeQuery("select city from login where name='"+nam+"'");
String NameOfVariable=rs.getString(1);
%>

Although I wouled rename your variable to something more readable and use standard naming conventions, ie personName.

The thing to remember is that Javascript is just like HTML. So anything in your JSP you output can be put inside a javascript function. The javascript will be created and sent to the users browser.

Given what I said you really should be able to work that out.

Seems as I don't know where you want to call the valid function from, i've just put it in another function, you can put it whereever your call is. Perhaps in the onload() event of the body.

According to me, you are going in wrong direction. JSP is a server-side technology and executes on the server then sent to the client. However, javascript executes on client-side.
