iScroll功能很强大，目前我只用来 自定义滚动条 以下简单介绍一下iscrol在移动端自定义滚动条时的使用和注意事项。

一、用法

iScroll对要滚动的元素进行初始化，且不限制一个页面中使用iScroll的元素个数。

使用iScroll时，DOM树的结构要足够简单，移除不必要的标签，避免过多的标签嵌套。

1、html部分

1.1、最优最简单的iScroll结构

<div id="wrapper">
<ul>
<li></li>
.....
</ul>
</div> 

本例中,ul标签将被滚动。iScroll一定要与滚动内容外的wrapper配合才能生效。

1.2、只有wrapper里的第一个子元素才可以滚动

因为只有wrapper里的第一个子元素才科院滚动，所以要让多个元素滚动 ，写法如下：

<div id="wrapper">
<div id="scroller">
<ul>
<li></li>
...
</ul>
<ul>
<li></li>
...
</ul>
</div>
</div> 

scroller这个元素可以滚动，即便它包含两个ul元素。

2、js调用部分

2.1 、使用onDomContentLoaded事件实现滚动

适用于滚动内容只包含文字、图片，并且所有的图片都有固定的尺寸

<script src="iscroll.js"></script>
<script>
var myscroll; //myscroll是全局变量，可以在任意地方调用
function loaded(){
myscroll=new iScroll("wrapper");
} window.addEventListener("DOMContentLoaded",loaded,false);
</script> 

2.2、使用onLoad事件实现滚动

因为DOMContentLoaded事件是载入DOM结构后就会被调用，所以在图片等元素未载入前可能无法确定滚动区域的长宽，此时可以使用onLoad事件来实现。

<script src="iscroll.js"><script>
<script>
var myscroll;
function loaded(){
setTimeout(function(){
myscroll=new iScroll("wrapper");
}，100 );
}
window.addEventListener("load",loaded,false);
</script> 

这种情况下iScroll会在页面资源（包括图片）加载完毕100ms之后得到初始化，这应该是一种比较安全的调用iScroll的方式。

2.3、弹框中的滚动条加载

弹框一般用display:none和display:block切换来实现。

display:none的元素浏览器没有渲染，所以无法计算滚动内容的高度。

所以在弹框调用show()显示出来后，再实例化滚动条区域。如下：

$("#mobile_show_duobao_all_num").show();
new iScroll('tc-wrapper2', {
scrollbarClass: 'myScrollbar' ,
hScrollbar:false,
vScroll:true,
hideScrollbar: false //是否隐藏滚动条
}); 

提示：出现滑动屏幕时，整个页面滑动的兼容性问题，解决办法如下：

document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false); 

2.4、iScroll传参

iScroll里的第二个参数允许你自定义一些内容，比如是否隐藏滚动条等。常用参数如下：

hScroll false 禁止横向滚动 true横向滚动 默认为true
vScroll false 精致垂直滚动 true垂直滚动 默认为true
hScrollbar false隐藏水平方向上的滚动条
vScrollbar false 隐藏垂直方向上的滚动条
fixedScrollbar 在iOS系统上，当元素拖动超出了scroller的边界时，滚动条会收缩，设置为true可以禁止滚动条超出
scroller的可见区域。默认在Android上为true， iOS上为false
fadeScrollbar 　 false 指定在无渐隐效果时隐藏滚动条
hideScrollbar 　 在没有用户交互时隐藏滚动条 默认为true
bounce 　启用或禁用边界的反弹，默认为true
momentum 　 启用或禁用惯性，默认为true，此参数在你想要保存资源的时候非常有用
lockDirection false取消拖动方向的锁定， true拖动只能在一个方向上（up/down 或者left/right）

2.5、通用方法

refresh 在DOM树发生变化时，应该调用此方法

eg: setTimeout(function () { myScroll.refresh(); }, 0);

3、css部分

自定义滚动条样式时需要给滚动条添加一个class参数，如下

var myscroll=new iScroll("wrapper",{
　　scrollbarClass: "myScrollbar"
}); 

滚动条是由两个元素组合而成的：容器和显示器。容器同wrapper的高度相同，而显示器则代表的是滚动条本身。

html结果如下：

<div class="myScrollbarV">
<div></div>
</div> 

css如下，可以自行修改：

@charset "utf-8";
/* CSS Document */
/**
*
* Horizontal Scrollbar

.myScrollbarH {
position:absolute;
z-index:100;
height:8px;

}
.myScrollbarH > div {

z-index:100;

}

}
