厉害了，dedecms利用ajax实现列表页的加载更多和无限加载功能

本文摘要：（一）加载更多功能步骤 dedecms 列表页加载更多插件，加载更多按钮为下拉自动触发形式，本次织梦dedecms实现点击下拉加载更多主要用到js技术。 步骤如下： 1、在/head头部加入js代码以及引入...

//列表页瀑布流无限加载代码
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;

//每页多少条，也就是一次加载多少条数据

//数据获取的起始位置。即limit条件的第一个参数。 
$typesql = $typeid ? " WHERE typeid=$typeid" : '';
//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;

<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js"></script>1

<script type="text/javascript">var loadConfig = { url_api:'/plus/list.php', typeid:{dede:field name="typeid"/}, 
page:2, pagesize:2, //这个就是滑动一次添加几条信息的参数设置 loading : 0, }function loadMoreApply(){ 
if(loadConfig.loading == 0){ var typeid = loadConfig.typeid; var page = loadConfig.page; var pagesize = loadConfig.pagesize; 
var url = loadConfig.url_api,data={ajax:'pullload',typeid:typeid,page:page,pagesize:pagesize}; 
var sTop = document.body.scrollTop || document.documentElement.scrollTop, dHeight = $(document).height(), 
cHeight = document.documentElement.clientHeight; console.log(dHeight); if (sTop + cHeight >= dHeight - cHeight) { 
loadConfig.loading = 1; function ajax(url, data) { $.ajax({url: url,data: data,async: false,type: 'GET',
dataType: 'json',success: function(data) { addContent(data);  }}); } ajax(url,data); } }} function addContent (rs){
 if(rs.statu== 1){ var data = rs.list; var total = rs.total; var arr=[]; var length = data.length; 
for(var i=0;i<length;i++){ arr.push('<li class="badcat-cell mui-media">'); arr.push('<a href="'+data[i].arcurl+'">');
 arr.push('<img class="mui-media-object mui-pull-right" src="'+data[i].picname+'">'); arr.push('<div class="mui-media-body">'); 
arr.push(''+data[i].title+''); arr.push('<p class="mui-ellipsis">'+data[i].info+'.</p>'); arr.push('</div>'); arr.push('</a>'); 
arr.push('</li>'); } $('.badcat').append(arr.join('')); loadConfig.load_num = rs.load_num; 
if(total<loadConfig.page*loadConfig.pagesize || loadConfig.page > loadConfig.load_num){ window.removeEventListener('srcoll',
loadMoreApply,false); } loadConfig.page++; loadConfig.loading = 0; }}function pullLoad(){ window.addEventListener('scroll',
 loadMoreApply, false);}pullLoad()checkMobile();</script>上面的代码中的$('.badcat').append(arr.join(''));里的badcat对应模板内列表的外框class属性。
arr.push部分对应的是列表中单篇文章的代码。这样就可以想要使用瀑布流无线加载了。
如果在其它页调用的话只需把代码中的typeid:{dede:field name="typeid"/} 修改为typeid:5（5 就是我们要调用文章的栏目ID）即可。
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} 

{dede:arclist row="15"}{/dede:arclist}

if(total<loadConfig.page*loadConfig.pagesize || loadConfig.page > loadConfig.load_num){ window.removeEventListener('srcoll',loadMoreApply,false);

$('<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('.badcat');
