1.0 什么是iscroll.js?

就是一个Javascript 库，或者说是一个JQuery 插件，能在手机端实现下拉刷新，滚动翻页,双指放大缩小等特效。

可以模拟原生iOS应用里的滚动列表操作。

2.0为什么要用iscroll.js ？

css属性overflow：scroll在ios5之前是不支持的，所以可以通过这个插件来在所有浏览器上支持这种滚动。

3.0如何使用iscroll,js?

直接看demo：

https://github.com/cubiq/iscroll/tree/master/demos。

简单来说就是

1.引入iscroll.js, 定义myScroll，内容里面div 父id写wrapper，子写scroller

function loaded () {
    myScroll = new IScroll(‘#wrapper‘, { mouseWheel: true, click: true });
}
document.addEventListener(‘touchmove‘, function (e) { e.preventDefault(); }, false);
</script>
