加载更多按钮

一,模板上要引入jq文件

二,模板

三,修改,plus/list.PHP 在require_once(dirname(__FILE__)."/../include/common.inc.php");

的下面增加一段

if(isset($_GET['ajax'])){

$typeid = isset($_GET['typeid']) ? intval($_GET['typeid']): 0;//传递过来的分类ID

$orderby = isset($_GET['orderby']) ? intval($_GET['orderby']): 1;

//print_r($orderby);exit;

//1id排,2hot排序

$page = isset($_GET['page']) ? intval($_GET['page']): 0;//页码

$pagesize = isset($_GET['pagesize']) ? intval($_GET['pagesize']): 10;//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。

$ntime2 = gmmktime(0, 0, 0, gmdate('m'), gmdate('d'), gmdate('Y'));

$limitday = $ntime2 - (40 * 24 * 3600);//40天内热文

$orwheres = " a.senddate > $limitday ";

//$typesql = $typeid ? " WHERE typeid=$typeid" : '';

if($orderby==1){//id降序

$typesql = $typeid ? " WHERE typeid=$typeid" : '';

} else{//hot排序

$typesql = $typeid ? " WHERE typeid=".$typeid." and ".$orwheres : " WHERE ".$orwheres;

}

//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(!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();

}

上一条：织梦dedecms对任意字段截取固定值并且多余部分用省略号代替 下一条:织梦列表页,支持顶(赞)和踩的功能,顶过后标红高亮显示
