PHP ajax no refresh paging, supports id positioning sample code

AJAX is a technology for exchanging data with a server to update part of a web page without reloading the entire page. This article mainly introduces the refresh-free implementation of php using ajaxPaging code

<?php 
Header("Content-Type:text/html; charset=utf-8"); 

function AjaxPage($Total,$ListNub,$CurrentPage,$Url,$AjaxAction,$HalfPer=&#39;&#39;,$ViewId=&#39;&#39;) 
{ 
//计算总页数 
$totalPage = @ceil($Total/$ListNub); 
$total=$totalPage-1; 
$re=""; 
//echo $CurrentPage; 
$re .= ( $CurrentPage > 0 ) 
?  
"<td><a  
href=\"javascript:$AjaxAction(&#39;$Url=0&#39;,&#39;$ViewId&#39;)\"\">首页</a></td>\n<td><a  
href=\"javascript:$AjaxAction(&#39;".$Url."=".($CurrentPage-1)."&#39;,&#39;$ViewId&#39;)\"\">上一页</a></td>\n" 
:  
"<td>首页</td>\n<td>上一页</td>\n"; 
for ( $i =  
$CurrentPage - $HalfPer,$i > 0 || $i = 0 ,     $j =  
$CurrentPage + $HalfPer, $j < $totalPage || $j = $totalPage;$i < $j ;$i++  
) 
{ 
  $re .= $i == $CurrentPage 
  ?  
"<td><b class=currentPage>[" . ( $i + 1 ) .  
"]</b></td>\n" 
  : "<td><a  
href=\"javascript:$AjaxAction(&#39;$Url=$i&#39;,&#39;$ViewId&#39;)\">" . ( $i + 1 ) .  
"</a></td>\n"; 
} 
$re .= ( $CurrentPage < $total  
) 
? "<td><a  
href=\"javascript:$AjaxAction(&#39;".$Url."=".($CurrentPage+1)."&#39;,&#39;$ViewId&#39;)\"\">下一页</a></td>\n<td><a  
href=\"javascript:$AjaxAction(&#39;".$Url."=".($total)."&#39;,&#39;$ViewId&#39;)\"\">尾页</a>\n</td>" 
:  
"<td>下一页</td>\n<td>尾页</td>\n"; 
$re="<table  
style=text-align:center><tr>$re</tr></table>"; 
return  
$re; 

} 
//总页数，传递的页面变量-当前页 url地址 前后各多少页 
$page = $_GET[&#39;page&#39;]; 
//echo
