求教高手, ext的json问题

json数据：
{
  results:1,
  rows:
  [{
  "endtime":"Sat Nov 06 00:00:00 CST 2010",
  "createtime":"Sat Nov 06 00:00:00 CST 2010",
  "template_code":"1000",
  "template_name":"1000",
  "objectType":"000"
  }]
}

var showInfoStore = new Ext.data.Store({
proxy: new Ext.data.ScriptTagProxy({
  url: '../../../tbExamTemplate!getExamTemplate.action'
  }),
  reader: new Ext.data.JsonReader({
  totalProperty: "results",
  root: "rows",
  id: "template_code"
  }, [
  {name:'template_code', mapping:'template_code'},
  {name:'template_name', mapping:'template_name'},
  {name:'createtime', mapping:'createtime'},
  {name:'endtime', mapping:'endtime'},
  {name:'objectType', mapping:'objectType'}
  ]),
  remoteSort: false
  });

showInfoStore.load();

调试结果，报缺少;{ results:1,rows:[{"endtime":"Sat Nov 06 00:00:00 CST 2010","createtime":"Sat Nov 06 00:00:00 CST 2010","template_code":"1000","template_name":"1000","objectType":"000"}]}

求高手解答，先谢了~~~~
