jQuery实现手机版页面翻页效果的简单实例

如下所示：

var page = 1; 
var size = 6; 
var mark = 0; 
var url = "{pigcms{:U('Order/index', array('page'=>'d%'))}"; 
var commentTpl = '<div style="margin-top: 10px">\ 
        <button data-oid="<order_id>" style="width: 65px; height: 20px;z-index:999;" onclick="comment()">去评价</button>\ 
        </div>';

          <a class="item-shop" href="{Pigcms{:U('Store/shop', array("store_id"=>"<store_id>"))}">\ 
            <i class="shop-icon"></i>\ 
            <span class="shop-name">{store_name}</span>\ 
            <i class="enter-icon"></i>\ 
          </a>\
