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：





<div>

 <ul class="list-content">

<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa.</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa.</a><span>[06-29]</span></li>

<ul>

<div>

<div>

<ul class="list-content">

<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

 <li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa...</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>

<li><a href="">aaaaaaaaaaaaaaaaaaa...</a><span>[06-29]</span></li>

<ul>

</div>



2,在src中创建servlet类：

使用request.setAttribute发送数据





public static ArrayList<String> list;

 static{

 list=new ArrayList<String>();

 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 

 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 

 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");

 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 

 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 

　　 public static ArrayList<String> listdc;

 static{

 listdc=new ArrayList<String>();

 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");

  ArrayList<String>list=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





<div>

     <ul class="list-content">

     

      <%

      ArrayList<String> list =(ArrayList<String>)request.getAttribute("new");

      if(list!=null)

       for(int i=0;i<list.size();i++){

      %>

       <li>

      <a href="" style=" rel="external nofollow" rel="external nofollow" width:644px">

        <% out.print(list.get(i)); %>

        </a><span>

        [06-29]

        </span>

       </li>

      <% }%>

     </ul>

    </div>

    <div>

     <ul class="list-content">

     <%ArrayList<String> listdc=(ArrayList<String>)request.getAttribute("dc");

      if(listdc!=null)

      for(int i=0;i<listdc.size();i++){

     %>

     <li>

     <a href="" style=" rel="external nofollow" rel="external nofollow" width:644px">

     <% out.print(listdc.get(i)); %>

     </a><span>

     [06-29]</span>

     </li>

     <% } %>

     </ul>

    </div>
