嗨，我是javascript和jquery的新手，我正在构建一个phonegap应用程序。
在我的应用程序中，我试图使用站点中演示的iscroll和iscrollview来实现pull-to-refresh功能http://www.x-services.nl/category/phonegap-cordova

我得到ReferenceError：iScroll未定义jquery.mobile.iscrollview.js指向iscrollview.js的第259行我无法找出这个引用错误的原因。
行为_subclass（IScroll，IScroll），iScrol未定义。这里iScroll var是一个超级构造函数类型的var我不明白造成的原因
我不知道为什么，但在1973行的iscroll.js中是窗口。IScroll=IScroll；
我认为这是错误的。
右边是window.iScroll=iScroll；
我改变并为我工作。
我不会称之为"奇怪的错误"，因为你的应用程序中似乎没有包含你在顶部的<script>标签中引用的所有JS文件。
