html 代码 一开始是需要显示的第一页
<div class="hot-product f15 fixed-Width clearfix" id="goods2">
<volist name="goods" id="goods_vo">
<div class="item2">
<div class="H_shangpin" style="background: url('{$goods_vo['banner'][0]}') no-repeat center ;background-size: contain"></div>
<div class="item3">
<p class="H_xianzhi">【{$goods_vo['fenlei']}】{$goods_vo['title']}</p>
<p class="color-red">
<span>￥{$goods_vo['pay']}</span>
<i class="color-b5 h_commodity fr"><del>￥{$goods_vo['yuan_pay']}</del></i>
</p>
<div class="clearfix shangpinming">
<p class="color-b5 h_commodity fl"><span>{$goods_vo['weizhi']}</span><span>{$goods_vo['shang_name']}</span></p>
<p class="fr color-b5 h_commodity ">{$goods_vo['time']}</p>
</div>
</div>
</div>
</volist>
</div>
自动监听下拉，当往下拉的时候就开始访问你指定的控制器
/*下拉分页*/
var nextp = "{$nextp}";//第几页
var oknext = 1;//加载开关
$(window).scroll(function () {
var di = $(window).scrollTop();//获取当前滚动条的位置
var ph = $(window).height();//当前窗口高度
di = di + ph;//最高拉到多少
var h = $(document).height();//允许多长滚动条
if (h - di < 100) {
if (nextp > 0 && oknext == 1) {
oknext = 0;
$.post("{:U('Index/goods')}", {p:nextp}, function (v) {//指定访问的控制器
if(v.index == 2){//这里我是做了一个判断，当需要一排显示两个就走if 当需要一排显示一个的时候就走else
if (v.status) {
oknext = 1;
nextp = v.nextp;
var list = v.list;
//console.log(list);
var html = '';
for (var i = 0; i < list.length; i++) {
html +='<div class="item2">'+
