jqueryeasyui中分页问题

Question

我用的是editable datagrid,这里边的分页要自己去实现，我后台可以得到当前页和行数，所以分页没什么问题，只是我不知道在哪里获取它点击下一页的这个事件，也就是说我不知道它在哪里设置当点击下一页的时候，去调用我后台分页的函数获得json？
代码：
$(function(){
var lastIndex;
$('#tt').datagrid({
title:'用户管理',
iconCls:'icon-edit',
width:800,
height:400,
singleSelect:false,
idField:'itemid',
url:'jsonsw!json.action',
pagination:true,
checkbox:true,
columns:[[
{field:'t_user_id',checkbox:true,align:'center'},
{field:'login_name',title:'用户名',width:180,align:'center'},
{field:'name',title:'姓名',width:100,align:'center'},
{field:'sex',title:'性别',width:80,align:'center'},
{field:'cdate',title:'创建日期',width:100,align:'center'},
{field:'p_name',title:'所属部门',width:150},
{field:'state',title:'状态',width:60,align:'center'
}
]],
toolbar:[{
text:'append',
iconCls:'icon-add',
handler:function(){
$('#tt').datagrid('endEdit', lastIndex);
$('#tt').datagrid('appendRow',{
itemid:'',
productid:'',
listprice:'',
unitprice:'',
attr1:'',
status:'P'
});
var lastIndex = $('#tt').datagrid('getRows').length-1;
$('#tt').datagrid('beginEdit', lastIndex);
}
},'-',{
text:'delete',
iconCls:'icon-remove',
handler:function(){
var row = $('#tt').datagrid('getSelected');
if (row){
var index = $('#tt').datagrid('getRowIndex', row);
$('#tt').datagrid('deleteRow', index);
}
}
},'-',{
text:'accept',
iconCls:'icon-save',
handler:function(){
$('#tt').datagrid('acceptChanges');
}
},'-',{
text:'reject',
iconCls:'icon-undo',
handler:function(){
$('#tt').datagrid('rejectChanges');
}
},'-',{
text:'getChanges',
iconCls:'icon-search',
handler:function(){
var rows = $('#tt').datagrid('getChanges');
alert('changed rows: ' + rows.length + ' lines');
}
}],
onBeforeLoad:function(){
$(this).datagrid('rejectChanges');
},
onClickRow:function(rowIndex){
alert("ss");
if (lastIndex != rowIndex){
$('#tt').datagrid('endEdit', lastIndex);
$('#tt').datagrid('beginEdit', rowIndex);
}
lastIndex = rowIndex;
}
});
});

easyui里面默认会向后台传递page和rows 这2个参数，你可以直接从request中获取。然后获取当前数目。就好控制分页了。示例：
Struts的action方法：
[code="java"]
public String data() throws Exception {
Map params = new HashMap();
userPage = userService.findByPage(params, page, rows);
Map map = new HashMap();
map.put("total", userPage.getTotalRows());
map.put("rows", userPage.getResultList());
Struts2Utils.renderJson(map);
return null;
}
[/code]
页面的js:
[code="js"]
grid = $('#user-table').datagrid({
url:'upc/user!data.action',
pagination:true,
...

});

[/code]
