Extjs导入Excel文件之后grid自动刷新显示刚插入的数据

 var winUpload = new Ext.Window({
             title: '导入excel文件',
             width: 400,
             height:200,
             listeners: {
                 close: function () {
                     store.load();
                     grid.getView().refresh();
                 }
             },
             minWidth: 300,
             closeAction:'hide' ,
             minHeight: 100,
             layout: 'fit',
             plain:true,
             bodyStyle:'padding:5px;',
             buttonAlign:'center',
             items: formUpload,
         });

Ext创建window窗体，添加监听listeners，当窗体关闭时执行store.load();grid.getView().refresh(); 加载数据源，刷新grid表格。
