dedecms 首页点击加载更多，已验证OK
使用方法：
1、加载是用AJAX，需要先引用jQuery
2、模板在arcajax.php第二十八行请自行按需修改（修改$innertext的值）
3、arcajax.php放到plus目录下
HTML和js代码：
<div id="scrollDiv">
{dede:arclist titlelen='40' infolen='200' row='3'}
循环部分
{/dede:arclist}
</div>
<div id="loading27">加载中</div>
<a href="{dede:field name='typeurl'/}" class="morearticle" id="getMore" pnum="2">
点击加载更多
</a>
<script type="text/javascript">
$("#getMore").click(function() {
var _this = $(this),
pnum = _this.attr("pnum"), //分页码
typeid = 0; // 栏目ID
if (pnum == 0) {
return false;
}
$("#loading27").show();
$.ajax({
url: '/plus/arcajax.php',
data: {
typeid: typeid,
pnum: pnum
},
success: function(data) {
if (data != '') {
$("#scrollDiv").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)
}
$("#loading27").hide();
}
})
return false;
})
</script>
