在ajax中使用json生成新闻页面
//实体类新闻
public class Easybuy_news {
/**
* 编号
*/
private int en_id;
/**
* 标题
*/
private String en_title;
/**
* 内容
*/
private String en_content;
/**
* 录入时间
*/
private String en_create_time;
public int getEn_id() {
return en_id;
}
public void setEn_id(int enId) {
en_id = enId;
}
public String getEn_title() {
return en_title;
}
public void setEn_title(String enTitle) {
en_title = enTitle;
}
public String getEn_content() {
return en_content;
}
public void setEn_content(String enContent) {
en_content = enContent;
}
public String getEn_create_time() {
return en_create_time;
}
public void setEn_create_time(String enCreateTime) {
en_create_time = enCreateTime;
}
public Easybuy_news() {
// TODO Auto-generated constructor stub
}
public Easybuy_news(int enId, String enTitle, String enContent,
String enCreateTime) {
super();
en_id = enId;
en_title = enTitle;
en_content = enContent;
en_create_time = enCreateTime;
}
}
//servlet类
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
Easybuy_newsdao dao=new Easybuy_newsdaoimpl();
Easybuy_news news=new Easybuy_news();
List<Easybuy_news> list=dao.findtitle();
request.setAttribute("list", list);
request.getRequestDispatcher("New.jsp").forward(request, response);
//response.sendRedirect(contextPath+"New.jsp");
out.flush();
out.close();
}
//jsp页面
<script type="text/javascript">
$(function(){
function intinews(){//使用ajax技术获取新闻列表数据
$.ajax({
"url" :"NewServlet",
"type" :"post",
"dataType" :"json",
"success" :preosn
});
}
function preosn(data){
var $newlist=$("#news").empty();
for(var i=0;i<data.length;){
$newlist.append(data[i].en_title+"<span>内容："+data[i].en_content+"</span>")
}
}
intinews();//执行新闻列表初始化工作
});
</script>
</head>
<body>
<div id="news">
</div>
</body>
我这边运行了但它不报错错，可就是在页面上没有加载出来，不知懂怎么回事了

data.length后面少了个i++。
