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($row[&＃39;goodpost&＃39;]+$row[&＃39;badpost&＃39;] == 0) { $row[&＃39;goodper&＃39;] = $row[&＃39;badper&＃39;] = 0; } else { $row[&＃39;goodper&＃39;] = number_format($row[&＃39;goodpost&＃39;]/($row[&＃39;goodpost&＃39;]+$row[&＃39;badpost&＃39;]),3)*100; $row[&＃39;badper&＃39;] = 100-$row[&＃39;goodper&＃39;]; } if(emptyempty($formurl)) $formurl = ”; if($formurl==’caicai’) { if($action == ‘good’) $digg = $row[&＃39;goodpost&＃39;]; if($action == ‘bad’) $digg = $row[&＃39;badpost&＃39;]; } else { $row[&＃39;goodper&＃39;] = trim(sprintf(“%4.2f”, $row[&＃39;goodper&＃39;])); $row[&＃39;badper&＃39;] = trim(sprintf(“%4.2f”, $row[&＃39;badper&＃39;])); $digg = ‘操作区：<a href=”Javascript：” Onclick=”Javascript：postDigg(’good’,’.$id.’)”>顶</a>（’.$row[&＃39;goodpost&＃39;].’） <a href=”Javascript：” Onclick=”Javascript：postDigg(’bad’,’.$id.’)”>踩</a>（’.$row[&＃39;badpost&＃39;].’）’; } AjaxHead(); echo $digg; exit(); ?>
