本文实例为大家分享了iScroll下拉刷新上滑加载展示的具体代码，供大家参考，具体内容如下

html代码：

    header   下拉刷新
 <!--
原始数据
-->
 上拉加载更多footer

css代码：

 body,ul,li {padding:0;margin:0;border:0} body {font-size:12px;font-family:microsoft yahei} .header {position:absolute;top:0; left:0;width:100%;height:45px;line-height:45px;font-size:16px;text-align:center;background:#e6e6e6} .footer {position:absolute;bottom:0; left:0;width:100%;height:48px;line-height:48px;font-size:16px;text-align:center;background:#e6e6e6} #wrapper {position:absolute;top:45px; bottom:48px;left:0;width:100%} #scroller li {padding:0 10px;height:60px;line-height:60px;background:#ecf6ff;margin-top:10px} #pullDown, #pullUp {padding:0 10px;height:30px;line-height:30px;color:#888;text-align:center} 

js代码：

 var myScroll,pullDownEl, pullDownOffset,pullUpEl, pullUpOffset,generatedCount = 0; function loaded() { //动画部分 pullDownEl = document.getElementById('pullDown'); pullDownOffset = pullDownEl.offsetHeight; pullUpEl = document.getElementById('pullUp'); pullUpOffset = pullUpEl.offsetHeight; myScroll = new iScroll('wrapper', { useTransition: true, topOffset: pullDownOffset, onRefresh: function () { if (pullDownEl.className.match('loading')) { pullDownEl.className = ''; pullDownEl.querySelector('.pullDownLabel').innerHTML = '下拉刷新'; } else if (pullUpEl.className.match('loading')) { pullUpEl.className = ''; pullUpEl.querySelector('.pullUpLabel').innerHTML = '上拉加载更多'; } }, onScrollMove: function () { if (this.y > 5 && !pullDownEl.className.match('flip')) { pullDownEl.className = 'flip'; pullDownEl.querySelector('.pullDownLabel').innerHTML = '释放刷新'; this.minScrollY = 0; } else if (this.y <5 && pulldownel.classname.match('flip')) { pulldownel.classname='' ; pulldownel.queryselector('.pulldownlabel').innerhtml='Pull down to refresh...' this.minscrolly=-pullDownOffset; } else if (this.y  (this.maxScrollY + 5) && pullUpEl.className.match('flip')) { pullUpEl.className = ''; pullUpEl.querySelector('.pullUpLabel').innerHTML = 'Pull up to load more...'; this.maxScrollY = pullUpOffset; } }, onScrollEnd: function () { if (pullDownEl.className.match('flip')) { pullDownEl.className = 'loading'; pullDownEl.querySelector('.pullDownLabel').innerHTML = '加载中'; pullDownAction(); // Execute custom function (ajax call?) } else if (pullUpEl.className.match('flip')) { pullUpEl.className = 'loading'; pullUpEl.querySelector('.pullUpLabel').innerHTML = '加载中'; pullUpAction(); // Execute custom function (ajax call?) } } }); loadAction(); } document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);//阻止冒泡 document.addEventListener('DOMContentLoaded', function () { setTimeout(loaded, 0); }, false); //初始状态，加载数据 function loadAction(){ var el, li; el = document.getElementById('thelist'); for (i=0; i<10; i++) { li = document.createElement('li'); li.innerText = '初始数据--' + (++generatedCount); el.appendChild(li, el.childNodes[0]); } myScroll.refresh(); } //下拉刷新当前数据 function pullDownAction () { setTimeout(function () { //这里执行刷新操作 myScroll.refresh(); }, 400); } //上拉加载更多数据 function pullUpAction () { setTimeout(function () { var el, li; el = document.getElementById('thelist'); for (i=0; i<10; i++) { li = document.createElement('li'); li.innerText = '上拉加载--' + (++generatedCount); el.appendChild(li, el.childNodes[0]); } myScroll.refresh(); }, 400); }
