Ajax Json使用

页面

  var uri=path+"/dataWrite/dataWrite_progress.action";$.ajax({     type: "post",     url: uri,     dataType: 'json',      success: function (info) {     json=eval(info);     properess=Number(json.properess);      tableName=json.tableName;     $("#message").text(tableName+"-更新进度:"+properess+"%");     } });

后台

Map<String,String> message=new HashMap<String,String>();message.put("tableName", tableName);message.put("properess",newjava.text.DecimalFormat("#.00").format(properess));String msg=JSONObject.fromObject(message).toString();response.getWriter().write(msg);
