ajax后台套用两层JSONOBJECT返回到前台的方法

前台JSP部分代码

$.ajax({    type : "post",         url : "loadScene.do",         data :  $("#sceneForm").serialize(),         async : true,         dataType : "json",        success : function(data) {        //alert("data" + data);                var scene_x = data.scene.x;        var scene_y = data.scene.y;  //好像没用        var scene_w = data.scene.width;//场景宽度        var scene_h = data.scene.height;//场景高度        var screen_w = screen.width;   //电脑屏幕宽度        var screen_h = screen.height;  //电脑屏幕高度}

后台servlet代码

JSONObject jo1 = new JSONObject();JSONObject jo2 = new JSONObject();List<String> data = new ArrayList<String>();data.add("100");data.add("100");data.add("10000");data.add("10000");data.add("a");data.add("name");data.add("view");jo1.put("x", data.get(0));jo1.put("y", data.get(1));jo1.put("width", data.get(2));jo1.put("height", data.get(3));jo1.put("stage", data.get(4));jo1.put("name", data.get(5));jo2.put("scene", jo1);PrintWriter out = response.getWriter();out.println(jo2);out.flush();out.close();
