介紹如何使用include,以下拉式選單為例
1.先開發好需要的模組,例如一個下拉式選單
nameSel.jsp

  <select name="name">
    <option value="johnny">Johnny</option>
    <option value="akey">Akey</option>
    <option value="Mary">Mary</option>
  </select>

2.需要此模組就可以使用include的方式加進來
samInclude.jsp

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    
    
        <form action="showName.jsp" method="POST">
            Please select a name :<jsp:include page="nameSel.jsp"/>
            <input type="submit" name="submit" value="Send"/>
        </form>
    
  

3.最後檢示一下是否可行,把下拉式選單的結果秀出來
showName.jsp

  <%@page contentType="text/html" pageEncoding="UTF-8"%>
  
    
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    
    
        <%
        String getname = request.getParameter("name");
        %>
        Select name is : <%=getname%>
