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>
