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();
?>
