JQuery插件：iScroll

页面布局：

<div id="wrapper">

  <div id="scroller">

   <div id="pullDown">

    <span class="pullDownIcon"></span><span class="pullDownLabel">下拉刷新...</span>

   </div>

   <ul id="thelist">

    <li>

     <img src="img/page1_img1.jpg" />

    </li>

    <li>

     <img src="img/page1_img2.jpg" />

    </li>

    <li>

     <img src="img/page1_img3.jpg" />

    </li>

    <li>

     <img src="img/page1_img1.jpg" />

    </li>

    <li>

     <img src="img/page1_img2.jpg" />

    </li>

    <li>

     <img src="img/page1_img3.jpg" />

    </li>

   </ul>

   <div id="pullUp">

    <span class="pullUpIcon"></span><span class="pullUpLabel">上拉加载中国足彩网...</span>

   </div>

  </div>翻页，是通过ajax请求，把页码传入一般处理程序，在一般处理程序中获得分页后的数据返回json数组对象。

下拉刷新：

/**

  * 下拉刷新 （自定义实现此方法）

  * myScroll.refresh(); // 数据加载完成后，调用界面更新方法

  */

  function pullDownAction() {

   setTimeout(function () {

    var el, li, i;

    el = document.getElementById('thelist');

    //==========================================

    $.ajax({

     type: "GET",

     url: "LoadMore.ashx",

     data: { page: generatedCount },

     dataType: "json",

     success: function (data) {

      var json = data;

      $(json).each(function () {

       li = document.createElement('li');

       // li.innerText = 'Generated row ' + (++generatedCount);

       li.innerHTML = '<img src="' + this.src + '"/>';

       el.insertBefore(li, el.childNodes[0]);

      })

     }

    });

    myScroll.refresh(); //数据加载完成后，调用界面更新方法  Remember to refresh when contents are loaded (ie: on ajax completion)

   }, 1000);  // <-- Simulate network congestion, remove setTimeout from production!

  }上拉刷新

function pullUpAction() {

   setTimeout(function () { 

    var el, li, i;

    el = document.getElementById('thelist');

    //==========================================

    $.ajax({
