帝国CMS二次开发下拉加载更多教程
首先调用20条默认的信息,代码如下
<section class=FConBig> <div class=divcon> <div id=divcon1> [e:loop={select * from www_11px_cn_ecms_news where classid in (2,3,4,5,6) order by newstime desc limit 20,6,24,0}] <dl class=FConSmall> <dt><a href=<?=$bqsr['titleurl']?>><img src=<?=$public_r['add_www_11px_cn_url']?><?=$bqr['titlepic']?> width=100%></a></dt> <dd> <a href=<?=$bqsr['titleurl']?> class=FConWza> <span class=FConWzTag><?=$bqsr[classname]?></span> <span class=FConTimeIco></span> <span class=FConWzTime><?=date('Y-m-d',$bqr[newstime])?></span> </a> <a href=<?=$bqsr['titleurl']?> class=FConWzDesc><?=$bqr['title']?></a> </dd> </dl> [/e:loop] </div> </div> </section> <div class=FConBig id=paiList></div> <div id=divcon2><div id=divload></div></div>
然后再是下拉加载的JS代码,
<script src=/Style/js/jquery-1.7.1.min.js></script> <script language=javascript type=text/javascript> $(document).ready(function(){ var page = 1;//这个不是真正的页数,而是位移量 var nextpage = 1; var wan=true; var totalheight = 0; function loadData(){ totalheight = parseFloat($(window).height()) + parseFloat($(window).scrollTop()); if ($(document).height() <= totalheight && wan==true) { // 说明滚动条已达底部 var cid = 0; page = nextpage; $.ajax({ url : '/Style/getajax.php', type:'get', data:{classid:cid,'next':page}, dataType : 'html', beforeSend:function(){ $('#divload').html('<div id=pullUp><p class=pullUpLabela><img src=/Style/css/img/wait1.gif width=20><span>正在载入</span></p></div>'); $('#divcon2').show(); wan=false; }, success : function(str){ if(str!=){ $('#divcon1').show(); $('#divcon2').hide(); $('#divcon1').append(str); nextpage++; wan=true; }else{ $('#divload').html('<div id=pullUp> <span class=pullUpLabel>加载完毕!</span></div>'); $('#divcon2').show(); } } }); }} $(window).scroll( function() { loadData(); }); }) </script>
最后就是getAJAX.php的加载代码
<?php $ye=strFilter($_GET[next]); $clasid=strFilter($_GET[classid]); if($clasid==1){$clasid=2,3,4,5,6;} if($clasid==7){$clasid=8,9,10,11,12,13;} if($clasid==14){$clasid=15,16,17;} if($clasid==18){$clasid=19,20,21,22;} if($clasid==23){$clasid=24,25,26,27,38;} if($clasid==28){$clasid=29,30,31,32;} if($clasid==33){$clasid=34,35,36,37;} if($clasid==0){ $aabbccdd = base64_encode(select * from www_11px_cn_ecms_news order by newstime desc limit); }else{ $aabbccdd = base64_encode(select * from www_11px_cn_ecms_news where classid in ($clasid) order by newstime desc limit); } function strFilter($str){ $str = str_replace('`', '', $str); $str = str_replace('·', '', $str); $str = str_replace('~', '', $str); $str = str_replace('!', '', $str); $str = str_replace('!', '', $str); $str = str_replace('@', '', $str); $str = str_replace('#', '', $str); $str = str_replace('$', '', $str); $str = str_replace('¥', '', $str); $str = str_replace('%', '', $str); $str = str_replace('^', '', $str); $str = str_replace('……', '', $str); $str = str_replace('&', '', $str); $str = str_replace('*', '', $str); $str = str_replace('(', '', $str); $str = str_replace(')', '', $str); $str = str_replace('(', '', $str); $str = str_replace(')', '', $str); $str = str_replace('-', '', $str); $str = str_replace('_', '', $str); $str = str_replace('——', '', $str); $str = str_replace('+', '', $str); $str = str_replace('=', '', $str); $str = str_replace('|', '', $str); $str = str_replace('', '', $str); $str = str_replace('[', '', $str); $str = str_replace(']', '', $str); $str = str_replace('【', '', $str); $str = str_replace('】', '', $str); $str = str_replace('{', '', $str); $str = str_replace('}', '', $str); $str = str_replace(';', '', $str); $str = str_replace(';', '', $str); $str = str_replace(':', '', $str); $str = str_replace(':', '', $str); $str = str_replace(''', '', $str); $str = str_replace('', '', $str); $str = str_replace('“', '', $str); $str = str_replace('”', '', $str); $str = str_replace(',', '', $str); $str = str_replace(',', '', $str); $str = str_replace('<', '', $str); $str = str_replace('>', '', $str); $str = str_replace('《', '', $str); $str = str_replace('》', '', $str); $str = str_replace('.', '', $str); $str = str_replace('。', '', $str); $str = str_replace('/', '', $str); $str = str_replace('、', '', $str); $str = str_replace('?', '', $str); $str = str_replace('?', '', $str); return trim($str); } require(../e/class/connect.php); if(!defined('InEmpireCMS')) { exit(); } require(../e/class/db_sql.php); require(../e/class/q_functions.php); $link=db_connect(); $empire=new mysqlquery(); $yema= $ye*20; $query = @mysql_query(base64_decode($aabbccdd). $yema,20) //执行SQL语句 or die(SQL语句执行失败2); while($rs = mysql_fetch_assoc($query)){ $src = $rs[id]; $xwclassid=$rs['classid']; $xwtitle=$rs['title']; $xwtitleurl=$rs['titleurl']; $xwtitlepic=$rs['titlepic']; $smalltext=$rs['smalltext']; $newstime=$rs['newstime']; $onclick=$rs['onclick']; $tuurl=$public_r[add_www_11px_cn_url]; $queryss = @mysql_query(select * from www_11px_cn_enewsclass where classid='$xwclassid') //执行SQL语句 or die(SQL语句执行失败3); while($rstt = mysql_fetch_assoc($queryss)){$xwclassname=$rstt[classname];$xwclasspath=$rstt[classpath];} ?> <dl class=FConSmall> <dt><a href=<?=$xwtitleurl?>><img src=<?=$tuurl?><?=$xwtitlepic?> width=100%></a></dt> <dd> <a href=<?=$xwtitleurl?> class=FConWza> <span class=FConWzTag><?=$xwclassname?></span> <span class=FConTimeIco></span> <span class=FConWzTime><?=date('Y-m-d',$newstime)?></span> </a> <a href=<?=$xwtitleurl?> class=FConWzDesc><?=$xwtitle?></a> </dd> </dl> <?php } ?>
这段代码加了写判断栏目的功能,大家按格式自行修改吧。
