起风网1. 01.php为主程序，调用smarty模板遍历输出：
<?php
include ‘./include/Mysql.class.php’;
include ‘./libs/Smarty.class.php’;
$db=new Mysql;
$smarty=new Smarty;
$lists=$db->getALL(‘users’);
$smarty->assign(‘lists’,$lists);
$smarty->display(‘list.html’);
?>
2. list.html模板:内容结合JS ajax使用：
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
<title>用户权限展示表</title>
</head>
<body>
//给table体设置一个div，方便js调用
<div id=”table”>
<table align=”center” border=”1″ width=”500″>
<center><h2>用户权限表</h2></center>
<tr>
<th>uid</th><th>用户名</th><th>密码</th><th>锁定状态</th><th>角色</th><th>操作</th>
</tr>
{foreach $lists as $list}
<tr align=”center”>
<td>{$list.uid}</td>
<td>{$list.username}</td>
<td>{$list.password}</td>
{if $list.is_lock==1}
<td><a href=”javascript:lock(0,{$list.uid});”>锁定</a></td>
{else}
<td><a href=”javascript:lock(1,{$list.uid})”;>取消锁定</a></td>
{/if}
{if $list.role==1}
<td>管理员</td>
{else}
<td>编辑者</td>
{/if}
<td><a href=”javascript:del({$list.uid})”>删除</a></td>
</tr>
{/foreach}
</table>
</div>
</body>
<script type=”text/javascript”>
function lock(lock,uid){
//创建ajax对象
var xhr=new XMLHttpRequest();
//打开一个链接
xhr.open(‘post’,’02.php’);
//设置头信息
xhr.setRequestHeader(‘content-type’,’application/x-www-form-urlencoded’);
//取值,多个参数用&分开
var data=”is_lock=”+lock+”&uid=”+uid;
//发送ajax数据请求
xhr.send(data);
//设置回调、监听函数
xhr.onreadystatechange=function(){
//如果ajax状态码响应正常且网络正常，获取响应文本
if(xhr.readyState==4&&xhr.status==200){
if(xhr.responseText){
document.getElementById(‘table’).innerHTML=xhr.responseText;
}else{
alert(“切换状态失败！”);
}
}
}
}
function del(uid){
var del=window.confirm(“您确定要删除吗？”);
if(del){
//创建ajax对象
var xhr=new XMLHttpRequest();
//打开一个链接
xhr.open(‘post’,’del.php’);
//设置header头
xhr.setRequestHeader(‘content-type’,’application/x-www-form-urlencoded’);
//data取值
var data=”uid=”+uid;
//发送ajax请求
xhr.send(data);
//设置监听
xhr.onreadystatechange=function(){
//如果ajax状态码响应正常且网络正常，获取响应文本
if(xhr.readyState==4&&xhr.status==200){
if(xhr.responseText){
//用ajax响应内容替换本模板中table标签的内容
document.getElementById(‘table’).innerHTML=xhr.responseText;
}else{
alert(“删除失败！”);
}
}
}
}
}
</script>
</html>
3. 02.php改变状态无刷新：
<?php
include ‘./include/Mysql.class.php’;
include ‘./libs/Smarty.class.php’;
$lock=$_POST[‘is_lock’];
$uid=$_POST[‘uid’];
$smarty=new Smarty;
$db=new Mysql;
$result=$db->update(‘users’,”is_lock=$lock”,”uid=$uid”);
if($result){
//修改成功重新遍历数据库并输出smarty模板
$lists=$db->getALL(‘users’);
$smarty->assign(‘lists’,$lists);
$smarty->display(‘list.html’);
}else{
echo false;
}
?>
4.del.php实现删除无刷新
<?php
include ‘./include/Mysql.class.php’;
include ‘./libs/Smarty.class.php’;
$db=new Mysql;
$smarty=new Smarty;
$uid=$_POST[‘uid’];
$res=$db->delete(‘users’,$uid);
if($res>0){
$lists=$db->getALL(‘users’);
$smarty->assign(‘lists’,$lists);
$smarty->display(‘list.html’);
}else{
echo false;
}
?>
