我一直在努力让Ram Swaroop's animateScroll.js与Telerik's AppBuilder合作。
我需要对animateScroll进行精细的细粒度控制，例如前后滚动事件处理，动画缓动和可控滚动速度（！）。但是，无论我做什么，滚动行为都不会实际发生，即使执行animateScroll 的工作（第162行）的jquery动画代码似乎也会触发，即使我可以通过使用console.log进行检测。
要清楚我所遵循的行为是animatescroll中的方法，您在现有元素中滚动，而不是滚动整个页面的默认行为。实现在元素内滚动引用包含元素作为参数。实际上，这种方法将任意包含div转换为＆＃34;滚动条＆＃34;并且可以在参数部分下的demo中看到。
我有一个大的appbuilder项目，所以我从Telerik的演示模板中创建了一个基本上空的appbuilder项目，我得到了相同的结果。我的假设是这个问题也会影响Phone和Cordova，因为它们非常相似。如果有人能够提供帮助，我会尽力将相同MIT许可下的调整版本提交给各种cordova / phonegap插件目录。它是一个非常好的滚动条 - 如果我可以在混合移动应用程序环境中使用它。
任何建议或帮助表示赞赏。接下来是非工作演示项目的Html代码，然后是animatescroll插件的完整源代码。
谢谢， 戴夫格尔丁
<div data-role="view" data-title="Home" data-layout="main" data-model="APP.models.home">
<h1 data-bind="html: title"></h1>
<div>
For Example:<br />
<div id="element-demo">
<p>
<button onclick="$('#last-paragraph').animatescroll({element:'#element-demo',padding:20});">Click here</button> to scroll to the last paragraph within this "div" element
</p>
<p>
This "div" element has a class-name "element-demo" which is the value passed for "element" option while calling the plugin.

答案 0 :(得分：1)
问题似乎是Android中已知且长期存在的错误，其中ScrollTop不能正常工作。

我能够通过添加
来获得动画滚动行为以开始运作对我来说最简单的解决方法是在容器div中添加内联样式，因此上面代码片段中的element-demo变为：
<div id="element-demo" style="height : 500px; overflow : auto;">
希望我可以将其与我的其他动态生成的位一起使用...如果我发现更有用的话，我会报告回来。
补充回答 经过一些更多的戳戳和刺激后，我发现了另一个问题并修复了它。
我非常确定animatescroll.js库中存在一个错误。具体来说，该选项允许您相对于指定元素滚动，而不是滚动到窗口或文档顶部的默认行为。在当前代码中使用了option元素但不完全 - animatescroll.js当前假设元素选项是您要滚动的元素的 immediate DOM父元素。在我的情况下，我滚动到一个跨度，它在一个p元素内部，在实际的“scroller”元素内 - 包含div。
所以，在animatescroll.js中我改变了这个：
$(opts.element).stop().animate({ scrollTop: this.offset().top - this.parent().offset().top + this.parent().scrollTop() - opts.padding }, opts.scrollSpeed, opts.easing);
到此：
$(opts.element).stop().animate({ scrollTop: this.offset().top - $(opts.element).offset().top + $(opts.element).scrollTop() - opts.padding }, opts.scrollSpeed, opts.easing);
现在一切都真的有用了。我已经通知了animatescroll.js的作者，所以他可以更新Git repo，假设他同意这种方法。
