Dedecms 5.7 列表页点击加载更多读取数据库内容

HTML和JS代码：

<div style="background: #FFF;text-align: center;font-size: 14px;color:#6D6D6D;">
  <a href="javascript:;" id="getMore" pnum="2">点击浏览更多内容</a>
</div>
<script type="text/javascript">
 $("#getMore").click(function(){
 var _this = $(this), 
 pnum = _this.attr("pnum"),//分页码
 typeid = {dede:field name='typeid' /};// 栏目ID自动获取
 if(pnum == 0){
 return false;
 }
 $.ajax({
 url: '/plus/arcajax.php',
 data: {typeid:typeid,pnum:pnum},
 success: function(data){
 if(data != ''){
 $(".index-list").append(data);//数据显示到页面
 _this.attr("pnum", Number(pnum)+1);//分页+1
 }else{
 _this.text("没有更多的数据");
 _this.attr("pnum", 0)
 }
 }
 })
 return false;
 })
</script>

使用方法：

1、加载是用AJAX，需要使用到jQuery；

2、模板在arcajax.php第二十八行请自行按需修改；

3、arcajax.php放到plus目录下。
