jquery 返回实体对象怎么取值啊

public String sayHello(){
HttpServletResponse response=ServletActionContext.getResponse();
response.setContentType("text/html;charSet=gbk");
try {
PrintWriter out = response.getWriter();
Book book=new Book();
book.setId(1);
book.setIsbn("1234");
book.setName("人中吕布");
out.print(book);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
$(function(){
$("input[type=button]:eq(0)").click(function(){
var options = {
type:"post",
target: "#myTargetDiv",
//dataType:'script',
success: getsc
};
//ajax一步上传表单
$("#myForm").ajaxSubmit(options);
});
});
function getsc(data)
{
//var obj = $(data);
//var name = data.name
alert($(data));/* 这几种都取不到..*/
} 这是前台ajax提交,想取book对象的属性，应该怎么取啊?

Book book=new Book();
book.setId(1);
book.setIsbn("1234");
book.setName("人中吕布");
out.print("{{ID:"+book.setId(1)+",Isbn:'"+book.setIsbn("1234")+"',Name:'"+book.setName("人中吕布")+"'}}"); //我在记事本中写的 可能会有语法错误反正就是返回json数据
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
$(function(){
$("input[type=button]:eq(0)").click(function(){
var options = {
type:"post",
target: "#myTargetDiv",
dataType:'json', //JSON类型
success: getsc
};
//ajax一步上传表单
$("#myForm").ajaxSubmit(options);
});
});
function getsc(data)
{

alert(data.ID);// 这是ID
alert(data.Isbn);// 这是Isbn
alert(data.Name);// 这是Name
} 这是前台ajax提交,想取book对象的属性，应该怎么取啊?

讨厌说话说一半的人！

Answer 2

Book book=new Book();
book.setId(1);
book.setIsbn("1234");
book.setName("人中吕布");
out.print(book);
把book序列化成json，
序列化对象有专门的json-lib
然后用response.getPrintWriter().print();
前台data.name就可以取值了

Answer 3

var options = {
type:"post",
target: "#myTargetDiv",
//dataType:'script',
success: getsc
};
这里改一下
var options = {
type:"post",
target: "#myTargetDiv",
dataType:'json',
success: function(book){
alert(book.name)
}
};

Answer 4

如果你前面的配置没错的话:

function getsc(data)
{
var obj = $(data);
alert(obj.find("name").text());
}
