关于AJAX做分页的问题

[obf13]

参考了网上几个代码，写的，但是click事件始终无法执行。

var curPage = 1; //当前页码
var total,pageSize,totalPage;
//获取数据
function getData(page){
    $.ajax({
        type: 'POST',
        url: 'page.php',
        data: {'pageNum':page-1},
        dataType:'json',
        success:function(json){
            $("#tablebody").empty();
            total = json.total; //总记录数
            pageSize = json.pageSize; //每页显示条数
            curPage = page; //当前页
            totalPage = json.totalPage; //总页数
            var table_html = "";
            var list = json.list;
            $.each(list,function(index,array){ //遍历json数据列
                table_html += "<tr><td><input type='checkbox' value='check'></td><td contentEditable='true'>"+array['id']+"</td><td>"+array['phonenumber']+"</td><td>"+array['username']+"</td><td><select id='permission' name='type'><option value ='present'>"+array['permission']+"</option><option value ='none'>无权限</option><option value ='all'>管理员</option><option value ='order'>订单管理</option><option value ='customer'>客户管理</option><option value ='supplier'>供应商管理</option><option value ='company'>车辆管理</option><option value ='warehouse'>仓库管理</option></select></td></tr>";            
            });
            $("#tablebody").append(table_html);
        },
        complete:function(){ //生成分页条
            getPageBar();
        },
        error:function(){
            alert("数据加载失败");
        }
    });
}

//获取分页条
function getPageBar(){
    //页码大于最大页数
    if(curPage>totalPage) curPage=totalPage;
    //页码小于1
    if(curPage<1) curPage=1;
    pageStr = "";

    //如果是第一页
    if(curPage==1){
        //
        //<li class='active'><a href='javascript:void(0)'>1</a></li>
        pageStr += "<li><a href='javascript:void(0)' rel='1'>1</a></li><li><a href='javascript:void(0)' rel='2'>2</a></li><li><a href='javascript:void(0)'>3</a></li><li><a href='javascript:void(0)' rel='"+(parseInt(curPage)+1)+"'>下一页</a></li><li><a href='javascript:void(0)' rel='"+totalPage+"'>尾页</a></li>";
    } else if(curPage>=totalPage){
        pageStr += "<li><a href='javascript:void(0)' rel='1'>首页</a></li><li><a href='javascript:void(0)' rel='"+(parseInt(curPage)-1)+"'>上一页</a></li><li><a href='javascript:void(0)' rel='1'>1</a></li><li><a href='javascript:void(0)' rel='1'>1</a></li><li><a href='javascript:void(0)' rel='2'>2</a></li><li><a href='javascript:void(0)'>3</a></li><li><a href='javascript:void(0)' rel='"+(parseInt(curPage)+1)+"'>下一页</a></li><li><a href='javascript:void(0)' rel='"+totalPage+"'>尾页</a></li>";
    } else {
        pageStr += "<li><a href='javascript:void(0)' rel='1'>1</a></li><li><a href='javascript:void(0)' rel='2'>2</a></li><li><a href='javascript:void(0)'>3</a></li><li><a href='javascript:void(0)' rel='"+(parseInt(curPage)+1)+"'>下一页</a></li><li><a href='javascript:void(0)' rel='"+totalPage+"'>尾页</a></li>";
    }

    $("#one").html(pageStr);
}


$(document).ready(function(){
    getData(1);
    $("#one li a").on('click',function(){
        alert('a被点击了');
        var rel = $(this).attr("rel");
        if(rel){
            getData(rel);
        }
    });
}); 

<?php
 
session_start();
include "conn/conn.php";
 
$page = intval($_POST['pageNum']);
 
$result = mysql_query("select id from tb_user");
$total = mysql_num_rows($result);//总记录数
 
$pageSize = 10; //每页显示数
$totalPage = ceil($total/$pageSize); //总页数
 
$startPage = $page*$pageSize;
$arr['total'] = $total;
$arr['pageSize'] = $pageSize;
$arr['totalPage'] = $totalPage;
$query = mysql_query("select id,phonenumber,username,permission from tb_user order by id desc limit $startPage,$pageSize");
while($row=mysql_fetch_array($query)){
     $arr['list'][] = array(
        'id' => $row['id'],
        'phonenumber' => $row['phonenumber'],
        'username' => $row['username'],
        'permission' => $row['permission']
     );
}
//print_r($arr);
echo json_encode($arr);
?>

<div class="manageNumber">
                    <nav aria-label="Page navigation" style="padding-left:50px">
                      <ul class="pagination pagination-sm" id="one">
                      </ul>
                    </nav>
                </div>

已解决

$(document).on('click','#pagecount li a',function(){
        var rel = $(this).attr("rel");
        if(rel){
            getData(rel);
        }
    });
