Question

您好我正在使用分页从数据库中检索数据，我能够检索但是我遇到的问题是我的分页中的下一个和最后一个按钮不起作用

这是我的代码 ** index.php **

<script type="text/javascript">
        function searchboxfun(numRecords, pageNum ) {
    $.ajax({
        type: "GET",
        url: "usersearchboxresult.php?search=" + document.getElementById("UserSearchBox").value,
        data: "show="+numRecords+"&pagenum="+pageNum,
        cache: false,
        beforeSend: function () { 
            $('#content').html('<img src="loader.gif" alt="" width="24" height="24" style=" padding-left:469px;">');
        },
        success: function(html) {    
            $("#RightPaneContainerDiv").html( html );
        }
    });
    return false;
}

function changeDisplayRowCount(numRecords)  {
    searchboxfun(numRecords, 1);
}

$( document ).ready(function() {
  searchboxfun(10, 1);
});  
</script>
 <form name="myForm" id="Myform" action="#" onsubmit="return  searchboxfun(); ">
<input type="text" id="UserSearchBox" name="UserSearchBox" style="width: 95%; margin-top: 15px; margin-left: 2%;" placeholder="Search Box"/>
 <div style="float: right; margin-right: 2%; margin-top: 0px;">
 <input type="submit" name="Search" value="Search" id="search" onclick='searchboxfun();'>
 </div>
</form>

usersearchboxresult.php

//Calculate the last page based on total number of rows and rows per page.

//this makes sure the page number isn't below one, or more than our maximum pages 
if ($pagenum < 1) { 
    $pagenum = 1;

    $pagenum = $last;

$lower_limit = ($pagenum - 1) * $page_limit;

 </div>

这里我的代码我可以从数据库中检索数据，但任何分页都不起作用

我错了，我怎样才能实现目标
