禁用JavaScript时IE6中的HTML5-HTML5inIE6whenJavaScriptisdisabled

This is dependent on your site and how much it relies on HTML5 elements. The easiest way to find out is to simply run your site on IE6-IE8 with Javascript disabled and see!

这取决于你的站点以及它对HTML5元素的依赖程度。最简单的方法就是在IE6-IE8上运行你的站点，禁用Javascript，然后就可以看到了!

With that said, you can expect your elements to mostly just not show up with styles. IE6-IE8 do not understand HTML5 elements and won't apply CSS to them if it doesn't expect them. The HTML5 Shiv is used to force IE to understand the new elements and then it automatically applies CSS to those elements.

说到这里，您可以预期您的元素大部分不会显示样式。IE6-IE8不理解HTML5元素，如果它不期望HTML5元素，也不会对它们应用CSS。HTML5 Shiv用来迫使IE理解新的元素，然后它自动地将CSS应用到这些元素上。

Ultimately I think Javascript being disabled is pretty rare now. Back in the day it was disabled to avoid annoying and useless flashy effects. Some people still do it, but so many sites require interactive behavior (the very site we are on now is heavily reliant upon JS) that users disabling JS are probably used to shit being broken across most of the internet.

最终，我认为Javascript被禁用是很少见的。在过去，它被禁用以避免恼人和无用的浮华效果。有些人仍然这样做，但是很多网站都需要交互行为(我们现在的网站非常依赖于JS)，因此禁用JS的用户可能已经习惯了在大多数互联网上被破坏。

It is not an unreasonable requirement that users have JS enabled, especially on such an old browser. If you design for the lowest common denominator you'll either end up supporting multiple code paths which takes a lot longer, or end up with an uninspiring website. Sometimes (government, school, large corporate websites) you need to do this, but for most of the web it's probably not going to kill you to simply have a JS Required message show up if the user does not have it on.

用户启用JS并不是不合理的要求，特别是在这样一个旧的浏览器上。如果你设计的是最小公分母，你要么会支持多段代码路径，这需要花费更多的时间，要么就会得到一个乏味的网站。有时候(政府、学校、大型公司网站)你需要这样做，但对于大多数网站来说，如果用户不打开JS要求的消息，你可能不会因此丧命。

Styling HTML 5 elements would be useless without Javascript in IE6 as it's necessary to document.createElement them. If you really need to support noJS IE6 users, don't use HTML5 elements or have backup div elements that do the same thing.

在IE6中，如果没有Javascript，样式化HTML 5元素将毫无用处，因为文档是必要的。createElement他们。如果你真的需要支持noJS IE6用户，不要使用HTML5元素，也不要使用做同样事情的div元素。

Who really disables Javascript these days? If they do, yes, there is no doubt that everything will break.

这些天谁真的禁用Javascript ?如果他们这样做了，是的，毫无疑问一切都会崩溃。

Also, it's not just for IE6. No version of IE before IE9 supports automatic styling for unknown elements. (Reference: A long digression into how browsers handle unknown elements)

而且，它不仅仅适用于IE6。在IE9之前，没有任何版本的IE支持对未知元素进行自动样式化。(参考:对浏览器如何处理未知元素的一种延伸)
