throws ServletException, IOException {

response.setCharacterEncoding("utf-8");

PrintWriter out = response.getWriter();
JSONObject jsonObj = JSONObject.fromObject(user);
out.print(jsonObj);
out.flush();
out.close();
}
//post
public void doPost(HttpServletRequest request, HttpServletResponse response)

JS核心代码
script type="text/javascript">
//get
$(document).ready(function() {
$('form .get').click(function() {
$.get('ajaxServlet',function(response,status,xhr){
var dataObj = eval("(" + response + ")");
$("#box").html(response);
alert(dataObj.name);
});
});
//post
$('form .post').click(function() {
$.post('ajaxServlet',function(response,status,xhr){
var dataObj = eval("(" + response + ")");
$("#box").html(response);
});
});
//ajax
$('form .ajax').click(function() {
alert($("[name='name']").val());
$.ajax({
type:'get',
url:'ajaxServlet',
data:{
name:$("[name='name']").val(),
age:$("[name='age']").val()
},
success:function(response, status, xhr){
$("#box").html(response);}
});
});
});
/script>
