jsp 使用request為頁(yè)面添加靜態(tài)數(shù)據(jù)的實(shí)例

來(lái)源：本站原創(chuàng)|時(shí)間：2020-01-11|欄目：JSP編程|點(diǎn)擊：次

一，在div中插入要顯示的數(shù)據(jù)！

1，以下是原網(wǎng)頁(yè)插入數(shù)據(jù)代碼：

<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中創(chuàng)建servlet類：

使用request.setAttribute發(fā)送數(shù)據(jù)

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，在需要插入數(shù)據(jù)的地方加入jsp腳本：

使用request.getAttribute接收數(shù)據(jù)

通過(guò)for循環(huán)打印數(shù)據(jù)

<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>
