1、列表连接用  <a href="javascript:void(0)"  onclick="go('url')"  class="item">

 function go(url){
    sessionStorage.setItem('index_list',$("#goods_list").html());
    sessionStorage.setItem('index_scroll',$(document).scrollTop());
    window.location.href = url;
    return false;
}

2、$(document).ready(function(){

var cdlist = sessionStorage.getItem('index_list');
if(null !== cdlist && '' !== cdlist){
    $("#goods_list").html(cdlist);    
    $(document).scrollTop(sessionStorage.getItem('index_scroll'));    
    //删除缓存    
    sessionStorage.removeItem('index_list');
    sessionStorage.removeItem('index_scroll');
 sessionStorage.removeItem('index_page');
    
}
