帝国cms 滚动加载更多文章

想要自己加载得要涉及到PHP+JQ+AJAX：

第一步：新建个php代码get_news_index.php 上传到 /e/action：

<?php
require('../class/connect.php');
require('../class/db_sql.php');
require('../data/dbcache/class.php');
if($_POST[action] == 'getmorenews'){
$table=htmlspecialchars($_POST[table]);
if(empty($_POST[orderby])){$orderby='newstime';}else{ $orderby=htmlspecialchars($_POST[orderby]);}
if(empty($_POST[myorder])){$myorder='desc';}else{ $myorder='asc';}
if(empty($_POST[limit])){$limit=3;}else{ $limit=(int)$_POST[limit];}
if(empty($_POST[classid])){$where=null;}else{ $where='where classid in('.$_POST[classid].')';}
if(empty($_POST[length])){$length=50;}else{ $length=(int)$_POST[length];}
if(empty($_POST[small_length])){$small_length=120;}else{ $small_length=(int)$_POST[small_length];}
$link=db_connect();
$empire=new mysqlquery();
$num =(int)$_POST['next'] *$limit;
if($table){
$sql=$empire->query("SELECT * FROM `".$dbtbpre."ecms_".$table."` $where order by $orderby $myorder limit $num,$limit");
while($r=$empire->fetch($sql)){
if($r[titlepic]==''){
$r[titlepic]=$public_r[news.url]."e/data/images/notimg.gif";
}
$oldtitle=stripSlashes($r[title]);
$title=sub($oldtitle,'',$length);
$smalltext=stripSlashes($r[smalltext]);
$smalltext=sub($smalltext,'',$small_length);
$classname=$class_r[$r[classid]][classname];
$newsurl=$public_r[newsurl];
$classurl=$newsurl.$class_r[$r[classid]][classpath];
?>
<article class="excerpt excerpt-one" data-id="<?=$r[classid]?>">
<header><a class="cat label label-important" href="<?=$class_r[$r[classid]]['classpath']?> "><?=$class_r[$r[classid]][bname]?><i class="label-arrow"></i></a>
<h2><a href="<?=$r[titleurl]?>" title="<?=$r[oldtitle]?>"><?=$r[title]?></a></h2>
<small class="text-muted"><span class="glyphicon glyphicon-picture"></span><?=$r[imgcount]?></small></header>
<p class="text-muted time"><?=$r[username]?> 发布于 <?=date('Y-m-d',$r[newstime])?></p>
<p class="focus"><a href="<?=$r[titleurl]?>" class="thumbnail"><img src="<?=$r[titlepic]?>" /></a></p>
<p class="note"><?=$smalltext?>...</p>
<p class="text-muted views">
<span class="post-views">阅读(<?=$r[onclick]?>)</span>
<span class="post-comments">评论(<?=$r[plnum]?>)</span><a href="JavaScript:makeRequest('<?=$public_r[news.url]?>e/public/digg?classid=<?=$r[classid]?>&id=<?=$r[id]?>&dotop=1&doajax=1&ajaxarea=diggnum<?=$r[id]?>','EchoReturnedText','GET','');" class="post-like" ><i class="glyphicon glyphicon-thumbs-up"></i>赞 (<span id="diggnum<?=$r[id]?>"><?=$r[diggtop]?></span>)</a>
<span class="post-tags">标签：<a href="/337/e/tags/?tagname=<?=stripSlashes($r[keyboard])?>" target="_blank" rel="tag" data-original-title><?=stripSlashes($r[keyboard])?></a></span></p>
</article>
//这部分代码添加自己的模板代码
<?php
}
}
}
db_close();
$empire=null;
?>

第二步要写js代码  ajaxShow.js：

$(function() {
    var i =0; //设置当前页数
    if (!NeuF) var NeuF = {};
    NeuF.ScrollPage = function (obj, options, callback) {
        var _defaultOptions = {delay: 500, marginBottom: 200}; //默认配置：延迟时间delay和滚动条距离底部距离marginBottom
        options = $.extend(_defaultOptions, options);
        this.isScrolling = false; //是否在滚动
        this.oriPos = 0; //原始位置
        this.curPos = 0; //当前位置
        var me = this; //顶层
        var $obj = (typeof obj == "string") ? $("#" + obj) : $(obj);
        //绑定滚动事件
        $obj.scroll(function (ev) {
            me.curPos = $obj.scrollTop();
            if ($(window).height() + $(window).scrollTop() >= $(document.body).height() - options.marginBottom) {
                if (me.isScrolling == true) return;
                me.isScrolling = true;
                setTimeout(function () {
                    me.isScrolling = false;
                }, options.delay);   //重复触发间隔毫秒
                if (typeof callback == "function") callback.call(null, me.curPos - me.oriPos);
            }
            ;
            me.oriPos = me.curPos;
        });
    };
    $(function () {
        window.scrollTo(0, 0); //每次F5刷新把滚动条置顶
        function show() {
            $.ajax({
                url: 'http://www.****.com/e/action/get_news_index.php',//自己的域名
                type: 'POST',
                data: {
                    "next": i,
                    'table': 'news',
                    'action': 'getmorenews',
                    'limit': 10,
                    'small_length': 120
                },
                dataType: 'html',
                beforeSend: function () {
                    $("#loadmore").show().html('<img  src="/307/skin/ecms103/images/loading.gif"/>正在努力加载中...');

                    $('#loadmore').attr('disabled', 'disabled');
                },
                success: function (data) {
                    if (data) {
                        $("#showajaxnews").append(data);

                        $("#loadmore").removeAttr('disabled');
                        $("#loadmore").html('滚动加载更多');
                        i++;
                    } else {
                        $("#loadmore").show().html("已全部加载完毕！");
                        console.log(data);
                        $('#loadmore').attr('disabled', 'disabled');
                        return false;
                    }
                }
            });

        };
        show();
        //marginBottom表示滚动条离底部的距离，0表示滚动到最底部才加载，可以根据需要修改
        new NeuF.ScrollPage(window, {delay: 1000, marginBottom: 0}, function (offset) {
            if (offset > 0) {
                setTimeout(show,1000)
            }
        });
    });
});

第三步：

要在 HTML 加入代码：

<div id="showajaxnews"> 列表加载这里面 </div>

<div id="loadmore">滚动加载更多</div>
