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：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | <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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | <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> |
