我想使用jsp验证用户在文本框中给出的值

Question

如何验证Textbox？代码如下。

我在行中创建了一个表格和文本框。我想验证该文本框。用户无法在{name="min[<%=i%>]"}文本框中输入小于{name="max[<%=i%>]"}的数据。并且数据最小和最大为{name="normal[<%=i%>]"}文本框

<%  
    Connection con = null;              
    con = connection.createConnection();
    System.out.println("Printing connection object "+con);
    Statement statement=con.createStatement(); 

    String sql ="SELECT * 
        FROM `itemfile` 
        WHERE IT_ITEMGRP IN ('A', 'K', 'T','M')";
    rs = statement.executeQuery(sql);
%>
