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});" rel="external nofollow" >锁定</a></td> {else} <td><a href="javascript:lock(1,{$list.uid})" rel="external nofollow" ;>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})" rel="external nofollow" >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; } ?>
