| 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();?> | |
