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
