jquery datagrid设置pageSize不起作用

没有吧，我就是在$('#dataGrid').datagrid('getPager').pagination({....})里配置的。 
$(document).ready(function(){ 
$('#majorTable').datagrid({ 
pagination : true, //分页显示 
title : "招聘职位", 
loadMsg : "正在加载，请稍后...", 
collapsible : true, //可折叠 
height : "auto", 
iconCls : "icon-ok", 
view: cardview, 
columns : [ [ 
{ 
title : "职位名称", 
field : "majorName", 
width : "100", 
resizable : false, 
align : "center" 
}, 
{ 
title : "招聘人数", 
field : "hireCount", 
width : "100", 
resizable : false, 
align : "center" 
}, 
{ 
title : "招聘类型", 
field : "hireType", 
width : "100", 
resizable : false, 
align : "center" 
}, 
{ 
title : "开始时间", 
field : "beginDate", 
width : "100", 
resizable : false, 
hidden : true, 
align : "center" 
}, 
{ 
title : "结束时间", 
field : "endDate", 
width : "100", 
resizable : false, 
hidden : true, 
align
