PHP模块代码：

class NewsAction extends Action{

public $page = '';  //分页，当前页数

function News(){
$list = M("News")->field('id,title')->where("status = 5")->findAll();

//分页
$list = $this->array_page($list);

//结束

$num = 0;

$URL = "http://www.baidu.com/";

$suffixName = '.html';
foreach($list as $key=>$val){
$num = $key + 1;
$str .= '  '.$num.").<a href='".$URL.$val['id'].$suffixName."' target='_blank'>".$val['title']."</a><br> ";
}
$str = preg_replace('/(.*),\s$/','\\1',$str);
$str .= "<div class='d_page'>".$this->page."</div>";

return $str;
}

//数组分页方法
/**
* array  $array 数组
* integer $showCount 每页的记录数
*------------------------------
* return array 返回数组
*/

前台Html代码：

<html>

<head>

<script type="text/javascript" charset="utf-8" src="__PUBLIC__/js/artDialog/artDialog.min.js"></script>

</head>

<body>

<script language="javascript" type="text/javascript">

//分页跳转

function showpage(url){
var testDialog;
testDialog = dialog('正在加载中...');
$.get(url,null,function(data){
//$("#con").append(data);
testDialog.close();
$("#con").html(data);
});
}

//提示缓冲框

function dialog(msg){
var testDialog;
testDialog = art.dialog({
lock: false,
title:'',
id:'loaddialog',
content:'<font color="#ff0000">'+msg+'</font>',
width:220
});
return testDialog;
}
