Chromecast支持什么HTML5和浏览器DOM [英] What of HTML5 and the Browser DOM is supported in Chromecast

问题描述

该文档显示Chromecast使用的是按比例缩小版本的Chrome浏览器。
是否存在支持的HTML5标签和支持的JavaScript DOM操作的列表？

The documnentation says that Chromecast is using a "Scaled down" version of the Chrome Browser. Is there somewhere a list of supported HTML5 tags and supported JavaScript DOM actions?

我想在HTML5中为Chromecast构建UX，可以从中进行远程控制手机或桌面浏览器。在此解决方案中，视频仅是次要的。

I like to build a UX in HTML5 for Chromecast that I can remote control from a mobile phone or desktop browser. Video is only secondary in this solution

推荐答案

我不知道这样的综合列表。您需要记住，Chromecast设备适合于媒体消耗，因此那里的MediaElements有很好的支持。实际上，它具有一些其他媒体扩展，例如EME和MSE。就DOM动作而言，我建议尽量减少（或尽可能远离）任何奇特的过渡；可以支持大多数事物，但尚未进行优化，并且在该设备上缺乏使它们平滑的所需资源（即硬件/内存）。

I am not aware of a comprehensive list like that. You need to keep in mind that Chromecast devices are geared toward consumption of media, so there is a pretty good support for the MediaElements there. In fact it has some additional media extensions such as EME and MSE. In terms of the DOM actions, I suggest to minimize (or better stay away, if possible) of any fancy transitions; the support for most things is there but it is not optimized and the resources required for those to be smooth (i.e. hardware/memory) is scarce on that device.

如果您需要了解更多有关覆盖率和性能的信息，建议您编写一个简单的应用程序，该程序可以将许多javascript测试页中的任何一个都放在实际的页面中，并在实际结果中查看设备。

If you need to find more about the coverage and performance, I suggest you write a simple app that puts any of the many javascript test pages and see the result on the actual device.
