jsp 使用request为页面添加静态数据的实例

一，在div中插入要显示的数据！

1，以下是原网页插入数据代码：

 

aaaaaaaaaaaaaaaaaaa[06-29]
aaaaaaaaaaaaaaaaaaa[06-29]
aaaaaaaaaaaaaaaaaaa.[06-29]
aaaaaaaaaaaaaaaaaaa[06-29]
aaaaaaaaaaaaaaaaaaa.[06-29]




aaaaaaaaaaaaaaaaaaa[06-29]
 
aaaaaaaaaaaaaaaaaaa[06-29]
aaaaaaaaaaaaaaaaaaa...[06-29]
aaaaaaaaaaaaaaaaaaa[06-29]
aaaaaaaaaaaaaaaaaaa...[06-29]

2,在src中创建servlet类：

使用request.setAttribute发送数据

public static ArrayList list;
 static{
 list=new ArrayList();
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
　　 public static ArrayList listdc;
 static{
 listdc=new ArrayList();
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 }
 public void doGet(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
  request.setCharacterEncoding("UTF-8");
  response.setContentType("text/html");
  ArrayListlist=getData();
  
  request.setAttribute("new", list);
  request.setAttribute("dc", listdc);
  request.getRequestDispatcher("/page/default.jsp").forward(request, response);
 }

3，在需要插入数据的地方加入jsp脚本：

使用request.getAttribute接收数据

通过for循环打印数据

     

     
      <%
      ArrayList list =(ArrayList)request.getAttribute("new");
      if(list!=null)
       for(int i=0;i
       

      
        <% out.print(list.get(i)); %>
        
        [06-29]
        
       
      <% }%>
     
    
    

     

     <%ArrayList listdc=(ArrayList)request.getAttribute("dc");
      if(listdc!=null)
      for(int i=0;i
     

     
     <% out.print(listdc.get(i)); %>
     
     [06-29]
     
     <% } %>
