jquery 异步数据的处理

jsp页面方法

$.post("../test",{uname:"John",pwd: "2pm"}, function(json){

alert(json);var data = eval("("+json+")");

alert(data);

alert(data.name);

alert('name:'+data['name']);

//user 是一个对象

var user = data.user;

//list 是一个数组

var list = data.list;

alert(user.sex);

alert('size:'+list.length);

for(var i=0;i<list.length;i++){

alert('a:'+list[i].a+' b:'+list[i].b);

}

});

后台java 代码：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

response.setContentType("text/html; charset=utf-8");

  PrintWriter out =response.getWriter();

try{

//要把数据转换成下面的格式

String str2="{name:'nae',user:{sex:'男',phone:'12345678'},list:[{a:1,b:1},{a:2,b:2},{a:3,b:3}]}";

out.write(str2);

out.close();

}catch (Exception e) {

log.equals(e);

}

}
