织梦dedecms首页文章列表无刷新实现时时顶、踩的方法

第一步:首先创建一个空白首页文件,在里面<body>区域加入以下调用代码:

<ol>

{dede:arclist row=’5′ titlelen=’20′}

<li><a href=”[field:arcurl/]“>[field:title/]</a> <span id=”diggNum[field:id/]“>操作区:<a href=”javascript:” onclick=”javascript:postDigg(‘good’,[field:id/])”>顶</a>([field:goodpost/]) <a href=”javascript:” onclick=”javascript:postDigg(‘bad’,[field:id/])”>踩</a>([field:badpost/])</span></li>

<script language=”javascript” type=”text/javascript”>getDigg([field:id/]);</script>

{/dede:arclist}

</ol>

这里的<script language=”javascript” type=”text/javascript”>getDigg([field:id/]);</script> 被加在了arclist标签里作为底层模板,是为了让每一篇文档都可以独立显示其顶和踩的状态。

第二步:在<head></head>区域内加入以下代码:

<script language=”javascript” type=”text/javascript” src=”{dede:global.cfg_cmsurl/}/include/dedeajax2.js”></script>

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

function postDigg(ftype,aid)

{

var taget_obj = document.getElementById(‘diggNum’+aid);

var saveid = GetCookie(‘diggid’);

if(saveid != null)

{

var saveidsaveids = saveid.split(‘,’);

var hasid = false;

saveid = ”;

j = 1;

for(i=saveids.length-1;i>=0;i–)

{

if(saveids[i]==aid && hasid) continue;

else {

if(saveids[i]==aid && !hasid) hasid = true;

saveid += (saveid==” ? saveids[i] : ‘,’+saveids[i]);

j++;

if(j==20 && hasid) break;

if(j==19 && !hasid) break;

}

}

if(hasid) { alert(“您已经顶过该帖,请不要重复顶帖!”); return; }

else saveid += ‘,’+aid;

SetCookie(‘diggid’,saveid,1);

}

else

{

SetCookie(‘diggid’,aid,1);

}

myajax = new DedeAjax(taget_obj,false,false,”,”,”);

var url = “{dede:global.cfg_phpurl/}/digg_ajax_index.php?action=”+ftype+”id=”+aid;

myajax.SendGet2(url);

DedeXHTTP = null;

}

function getDigg(aid)

{

var taget_obj = document.getElementById(‘diggNum’+aid);

myajax = new DedeAjax(taget_obj,false,false,”,”,”);

myajax.SendGet2(“{dede:global.cfg_phpurl/}/digg_ajax_index.php?id=”+aid);

DedeXHTTP = null;

}

</script>

这一段代码主要就是引入织梦系统自带的Ajax框架(dedeajax2.js)和两个操作的函数(postDigg(ftype,aid)与getDigg(aid))

第三步:在/plus/ 文件夹下创建一个名为digg_ajax_index.php的文件,该文件的内容为:

<?php

/**

* CMS集中营 www.cmsjzy.cn

*/

require_once(dirname(__FILE__)。”//include/common.inc.php”);

$action = isset($action) ? trim($action) : ”;

$id = emptyempty($id)? 0 : intval(preg_replace(“/[^\d]/”,”, $id));

if($id < 1)

{

exit();

}

$maintable = ‘dede_archives’;

if($action == ‘good’)

{

$dsql->ExecuteNoneQuery(“Update `$maintable` set scores = scores + {$cfg_caicai_add},goodpost=goodpost+1,lastpost=”。time()。” where id=’$id’”);

}

else if($action==’bad’)

{

$dsql->ExecuteNoneQuery(“Update `$maintable` set scores = scores – {$cfg_caicai_sub},badpost=badpost+1,lastpost=”。time()。” where id=’$id’”);

}

$digg = ”;

$row = $dsql->GetOne(“Select goodpost,badpost,scores From `$maintable` where id=’$id’ “);

if(!is_array($row))

{

exit();

}

if($row['goodpost']+$row['badpost'] == 0)

{

$row['goodper'] = $row['badper'] = 0;

}

else

{

$row['goodper'] = number_format($row['goodpost']/($row['goodpost']+$row['badpost']),3)*100;

$row['badper'] = 100-$row['goodper'];

}

if(emptyempty($formurl)) $formurl = ”;

if($formurl==’caicai’)

{

if($action == ‘good’) $digg = $row['goodpost'];

if($action == ‘bad’) $digg = $row['badpost'];

}

else

{

$row['goodper'] = trim(sprintf(“%4.2f”, $row['goodper']));

$row['badper'] = trim(sprintf(“%4.2f”, $row['badper']));

$digg = ‘操作区:<a href=”javascript:” onclick=”javascript:postDigg(\’good\’,’。$id.’)”>顶</a>(’。$row['goodpost'].’) <a href=”javascript:” onclick=”javascript:postDigg(\’bad\’,’。$id.’)”>踩</a>(’。$row['badpost'].’)’;

}

AjaxHead();

echo $digg;

exit();

?>
