iscroll上拉加載更多下拉重新整理

項目中需要用到滾動，本想自己寫，但總會有一些大bug，最後不得不采用iscroll來做，不過這個做起來還真是友善，效果圖如下：

這個是最終的項目效果圖，下面貼出代碼供大家參考：

注意：所貼代碼并不是上面的全部代碼，經過修改過後的

結構：

<div id="wrapper">
	<div id="scroller">
		<div id="pullDown">
			<span class="pullDownLabel">下拉重新整理</span>
		</div>
		<ul id="thelist">
			<!--<li>原始資料</li>-->
		</ul>
		<div id="pullUp">
			<span class="pullUpLabel">上拉加載更多</span>
		</div>
	</div>
</div>
           

js代碼：

var myScroll,pullDownEl, pullDownOffset,pullUpEl, pullUpOffset,generatedCount = 0;

function loaded() {
	//動畫部分
	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 = '下拉重新整理';
			} else if (pullUpEl.className.match('loading')) {
				pullUpEl.className = '';
				pullUpEl.querySelector('.pullUpLabel').innerHTML = '上拉加載更多';
			}
		},
		onScrollMove: function () {
		
			if (this.y > 5 && !pullDownEl.className.match('flip')) {
				pullDownEl.className = 'flip';
				pullDownEl.querySelector('.pullDownLabel').innerHTML = '釋放重新整理';
				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 = 'flip';
				pullUpEl.querySelector('.pullUpLabel').innerHTML = '釋放重新整理';
				this.maxScrollY = this.maxScrollY;
			} 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 = '加載中';				
				pullDownAction();	// Execute custom function (ajax call?)
			} else if (pullUpEl.className.match('flip')) {
				pullUpEl.className = 'loading';
				pullUpEl.querySelector('.pullUpLabel').innerHTML = '加載中';				
				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);

//初始狀态，加載資料
function loadAction(){
	var el, li;
	el = document.getElementById('thelist');
	for (i=0; i<10; i++) {
		li = document.createElement('li');
		li.innerText = '這個是資料哦--' + (++generatedCount);
		el.appendChild(li, el.childNodes[0]);
	}
	myScroll.refresh();
}

//下拉重新整理目前資料
function pullDownAction () {
	setTimeout(function () {
		//這裡執行重新整理操作
		
		myScroll.refresh();	
	}, 400);
}

//上拉加載更多資料
function pullUpAction () {
	setTimeout(function () {
		var el, li;
		el = document.getElementById('thelist');
		for (i=0; i<10; i++) {
			li = document.createElement('li');
			li.innerText = '上拉加載--' + (++generatedCount);
			el.appendChild(li, el.childNodes[0]);
		}
		myScroll.refresh();
	}, 400);
}
           

大家可以根據自己的需求去修改為自己想要的效果，注意需要先引入iscroll檔案才可以。
