javascript - HTML 单选按钮：隐藏项目符号
我希望一个特定的表单组件充当单选按钮（一次只能选择一个选项）。但是，我不希望无线电子弹显示选择其他呈现方法，例如选择高光或其他方法。这将允许优雅降级：如果用户浏览器不支持 Javascript，它只会降级为基本单选按钮。我希望通过 Javascript 或 CSS 隐藏项目符号按钮。有谁知道怎么做？谢谢。
html - Can you use an HTML5 video/audio player with a Flash fail-safe?
I'm trying to figure out my options when it comes to playing both audio and video via the web. I'm sold on the HTML 5 <video /> and <audio />. But, I'd like to be able to display flash video/audio if the HTML video/audio fails.
Is there an easy way to detect if the video/audio is not playing for any reason, then swap out the HTML5 player for a Flash player?
