datagrid列表绑定上下键

onLoadsSuccess时取得datagrid panel

var panel = $("#ypxxdataGridDemo").datagrid('getPanel').attr('tabindex', 0);

//多次加载先取消在绑定

panel.off("keydown").bind('keydown', function(e) {

switch (e.keyCode) {

case 38: // up

CHIS.selectRow(true,$("#ypxxdataGridDemo"),$("#ypxxdataGridDemo").datagrid("options").onSelectFn);

return false;

case 40: // down

CHIS.selectRow(false,$("#ypxxdataGridDemo"),$("#ypxxdataGridDemo").datagrid("options").onSelectFn);

return false;

}

});

},
