BlackBerry PlayBook Webworks：低帧率

[英]BlackBerry PlayBook Webworks: Low frame rate

原文 2012-07-25 06:03:08 5 1 javascript/ blackberry/ blackberry-webworks/ blackberry-playbook/ playbook

While my blackberry webworks app works very well on Blackberry 7.0 and 7.1 devices, it has a very low frame rate on PlayBooks. 虽然我的Blackberry Webworks应用程序在Blackberry 7.0和7.1设备上可以很好地运行，但在PlayBooks上的帧率却非常低。 For example when scrolling on a page or when drawing stuff on a canvas. 例如，在页面上滚动或在画布上绘制内容时。 I use the jQuery JavaScript extension. 我使用jQuery JavaScript扩展。

What could be the reason for the low frame rate that makes it rather unusable on PlayBook devices? 低帧速率导致它在PlayBook设备上相当不可用的原因可能是什么？

Any help would be appreciated. 任何帮助，将不胜感激。 Thank you in advance! 先感谢您！

Recommend using jQuery Mobile over jQuery-UI as it is more optimized for mobile. 推荐在jQuery-UI上使用jQuery Mobile，因为它已针对移动设备进行了优化。 jQuery in general generates a lot of page repaints, which is expensive for smooth UI. jQuery通常会生成很多页面重绘，这对于平滑的UI而言是昂贵的。 Do you have many pages in your app? 您的应用程序中有很多页面吗？

Finally, if you are using a JavaScript library like iScroll to introduce kinetic scrolling, I'd recommend disabling that - the native web engine does this for you. 最后，如果您正在使用iScroll之类的JavaScript库来引入动态滚动，则建议禁用该功能-本机Web引擎会为您完成此操作。
