注意:很多人在调试这个功能的时候可能把标签写成了{dede:list pagesize='10'}{/dede:list} 要用{dede:arclist row="15"}{/dede:arclist}才可以,不然文章是加载不出来的!
四、有些网友的需求添加了“加载完成”的提示! 找到如下代码:
if(total<loadConfig.page*loadConfig.pagesize || loadConfig.page > loadConfig.load_num){ window.removeEventListener('srcoll',loadMoreApply,false); }在判断语句的最后加上如下代码:
$('<div style="width:100%; float:left; text-align:center; padding: 10px 0px; color:#fff; background:#00aa98; font-size: 16px;">加载完成</div>').insertAfter('.listbox');加上这段代码的意思是:当文章全部加载完的时候在所有文章最底部显示“加载完成”的提示! 在类为“.listbox”的标签下面插入“加载完成”的DIV标签(注意一定要对应替换自己的类名称)!如图:

另外在频道页,也就是带多个下级子栏目的频道页,这个代码还有点问题,需要修改plus.php。频道页做不到无限加载,是因为在文章表里面只有子栏目 typeid 而没且关联的父栏目 typeid 所以在查询文章 dede_archives 表的时候,父栏目 typeid 是没有对应的文章。所以为了解决这个问题我在原来的基础上加了个判断,如果当传过来的 typeid 下有子栏目的时候调用该栏目下的所以子栏目文章。
下面就把修改后的完整代码贴出来
if(isset($_GET['ajax'])){ $typeid = isset($_GET['typeid']) ? intval($_GET['typeid']): 0;//传递过来的分类ID $page = isset($_GET['page']) ? intval($_GET['page']): 0;//页码 $pagesize = isset($_GET['pagesize']) ? intval($_GET['pagesize']): 15;//每页多少条,也就是一次加载多少条数据 $start = $page>0 ? ($page-1)*$pagesize : 0;//数据获取的起始位置。即limit条件的第一个参数。 //获取频道栏目下的子栏目ID $yz_typeid = $dsql->GetOne("SELECT COUNT(id) as num FROM `dede_arctype` WHERE reid=$typeid "); if($yz_typeid['num']!=0){ $sql = "SELECT * FROM `dede_arctype` WHERE reid=$typeid"; $dsql->SetQuery($sql); $dsql->Execute('yz_id'); $typepdid = ""; $yz = 1; while($row = $dsql->GetArray("yz_id")){ if($yz_typeid['num'] == $yz){ $typepdid .= "(typeid=".$row['id'].")"; }else{ $typepdid .= "(typeid=".$row['id'].") or "; $yz += 1; } } // echo $yz_typeid['num']."+++".$typepdid; //exit(); }else { $typepdid = "typeid=$typeid"; } $typesql = $typeid ? " WHERE $typepdid" : '';//这个是用于首页实现瀑布流加载,因为首页加载数据是无需分类的,所以要加以判断,如果无需 $total_sql = "SELECT COUNT(id) as num FROM `dede_archives` $typesql "; $temp = $dsql->GetOne($total_sql); $total = 0;//数据总数 $load_num =0; if(is_array($temp)){ $load_num= round(($temp['num']-15)/$pagesize);//要加载的次数,因为默认已经加载了 $total = $temp['num']; } $sql = "SELECT a.*,t.typedir,t.typename,t.isdefault,t.defaultname,t.namerule, t.namerule2,t.ispart, t.moresite,t.siteurl,t.sitepath FROM `dede_archives` as a JOIN `dede_arctype` AS t ON a.typeid=t.id $typesql ORDER BY id DESC LIMIT $start,$pagesize"; $dsql->SetQuery($sql); $dsql->Execute('list'); $statu = 0;//是否有数据,默认没有数据 $data = array(); $index = 0; while($row = $dsql->GetArray("list")){ $row['description'] = cn_substr($row['description'],90); $row['id'] = $row['id']; $row['filename'] = $row['arcurl'] = GetFileUrl($row['id'], $row['typeid'],$row['senddate'],$row['title'],$row['ismake'], $row['arcrank'],$row['namerule'],$row['typedir'],$row['money'], $row['filename'],$row['moresite'],$row['siteurl'],$row['sitepath']); $row['typeurl'] = GetTypeUrl($row['typeid'],$row['typedir'], $row['isdefault'],$row['defaultname'],$row['ispart'], $row['namerule2'],$row['moresite'],$row['siteurl'],$row['sitepath']); $row['waparcurl'] = preg_replace("(.*/m/)","/",$row['arcurl']); if($row['litpic'] == '-' || $row['litpic'] == ''){ $row['litpic'] = $GLOBALS['cfg_cmspath'].'/images/defaultpic.gif'; } if(!preg_match("#^http:\/\/#i", $row['litpic']) &&$GLOBALS['cfg_multi_site'] == 'Y'){ $row['litpic'] = $GLOBALS['cfg_mainsite'].$row['litpic']; } $row['picname'] = $row['litpic'];//缩略图 //$row['stime'] = GetDateMK($row['pubdate']); $row['stime'] = date('Y-m-d H:i', $row['pubdate']); $row['click'] = $row['click']; $row['typelink'] = "".$row['typename']."";//分类链 $row['fulltitle'] = $row['title'];//完整的标题 $row['shorttitle'] = $row['shorttitle'];//副标题 $row['title'] = cn_substr($row['title'], 80);//截取后的标题 $data[$index] = $row; $index++; } if(!empty($data)){ $statu = 1;//有数据 } $result =array('statu'=>$statu,'list'=>$data,'total'=>$total,'load_num'=>$load_num); echo json_encode($result);//返回数据 exit(); }
