springmvc结合ajax的分页功能

var itemCount;//符合查找条件的商品总页数，分页参考
var pageIndex = 0;//当前页，默认为0
var pageSize = 8;//每页显示个数为8

//按条件查找用户
function searchItem(pageIndex,pageSize){

//清空要append的目的位置
$('#searchItem').empty();

$('.ajax_page').empty();

var url = "${ctx}/crms/orderCenter/findItemList";
$.post(url,{"pageIndex":0,"pageSize":8},function(data){
var items = data.itemList;
var appendItem = '';
itemCount = Math.ceil(data.itemCount/8);
//查询结果所有的商品
$.each(items,function(i,result){
appendItem = "<tr class='w790 h55'><td class='w75 text-center bgc_fafafa'>"
+ "<input type='text' class='num_iid' value='"+result.numIid+"'>"
+ "<div onclick='addNumIid("+result.numIid+")' class='w20 h20 bgc_e0e6ef margin0_auto b_radius5 GXK'></div>"
+ "</td><td class='w620 bgc_fafafa'><img class='w54 h45 m_t5 m_l10 m_r20 f_l' src='"+result.url+"'><p class='w400 h55 lh55 f_l'>"+result.title+"</p></td>"
+ "<td class='w78 text-center bgc_fafafa'>"+result.price+"</td></tr>";
$('#searchItem').append(appendItem);
});
//分页
var page = '<div id="userPage" align="center" ><font size="2">共'+itemCount+'页</font><font size="2">第'
+(pageIndex+1)+'页</font> <a href="javascript:void" onclick="goToFirstPage()" id="aFirstPage" >首页</a>'
