extjs 不显示但是不报错

其实这是我犯的最低级的错误,我在火狐上运行,firebug没有报错,而后台的数据能正常获取,但是extjs就是不能显示.

		<script type="text/javascript">
          Ext.onReady(function(){
             //创建一个store
             var store=new Ext.data.Store({
                //从服务器端加载
                url:"ext/xml/Employee.xml" ,
                reader:new Ext.data.XmlReader({
                  //是以那个标签为一记录的
                  record:"employee",
                  id:"empno",
                  totalRecords:"@total"
                },[
                  {name:"empno"},
                  {name:"name"},

                region:"north"                 
             });
             
             //定义显示详细信息模版
             var bookTplMarkup=[

                   bodyStyle:{

                   },
                   html:"测试的显示的信息"
                  }
                ]
             });
             
             
             grid.getSelectionModel().on("rowselect",function(sm,rowIndex,r){
              //得到panel对象
              var detailPanel=Ext.getCmp("detailPanel");
              bookTpl.overwrite(detailPanel.body,r.data);
             });
             
             //手动调用加载
             store.load({callback:function(){
             //  alert(Ext.util.JSON.encode(store.getAt(0).data));
             }});
          });		
		</script>

注意看代码的这里,我也没想到会犯这么低级错误,所以检查错误的时候需要仔细.

仔细看这里:

之中的renderTo写成了render,火狐是不会报错的.也不显示,
