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

<%
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>
