How to redirect if javaScript is disabled?
提问by zeckdude
I have a site which relies heavily on javaScript. I created a mirror site, which has all the JS as well as all the elements that require JS removed. What is a good, easy way to redirect users to the mirror site if they don't have javaScript enabled?
我有一个严重依赖 javaScript 的网站。我创建了一个镜像站点，其中包含所有 JS 以及所有需要删除 JS 的元素。如果用户没有启用 javaScript，有什么好的、简单的方法可以将用户重定向到镜像站点？
I tried this, but it doesn't seem very good:
我试过这个，但它似乎不是很好：
<noscript>
<meta http-equiv="refresh" content="0; URL=nojs/index.php">
</noscript>
I also tried to putting header-redirect into the noscript tag, but that didn't work.
我还尝试将 header-redirect 放入 noscript 标记中，但这不起作用。

Make the no-JavaScript version of the site the default. Include a small script in there to redirect to the scripted site.
将站点的无 JavaScript 版本设为默认版本。在其中包含一个小脚本以重定向到脚本站点。
Or, abandon the use of a redirect entirely and go with Progressive Enhancement
或者，完全放弃使用重定向并使用渐进增强

<noscript>
<p>This site is best viewed with Javascript. If you are unable to turn on Javascript, please use this <a href="http://sitewithoutjavascript.com">site</a>.</p>
</noscript>
Some people purposely disable Javascript, and you might want to give them a chance to turn it on before redirecting them.
有些人故意禁用 Javascript，您可能希望让他们有机会在重定向之前打开它。

Use this code that I came up with:
使用我想出的这段代码：
<noscript>
<style>html{display:none;}</style>
<meta http-equiv="refresh" content="0.0;url=nojs/index.php">
</noscript>
It uses style to block what's on the page so then people won't notice anything before it redirects. The only thing that annoys me is that I want something better than meta refresh as that can be blocked on some browsers like IE. A PHP header isn't really a solution as you can't put it in a noscripttag as it will just ignore it and write it out straight away.
它使用样式来阻止页面上的内容，因此人们在重定向之前不会注意到任何内容。唯一让我烦恼的是我想要比元刷新更好的东西，因为它可以在某些浏览器（如 IE）上被阻止。PHP 标头并不是真正的解决方案，因为您不能将其放入noscript标签中，因为它会忽略它并立即将其写出。

I wouldn't do client-side redirection, as that might seem annoying to the user. Instead, what I would do is use <noscript>to show the content of this JS-less site on the same page. It may be more work, but it would definitely be a smoother experience.
我不会做客户端重定向，因为这对用户来说可能很烦人。相反，我要做的是<noscript>在同一页面上显示这个无 JS 站点的内容。这可能需要更多的工作，但肯定会是一个更流畅的体验。

I came up with a better solution than having to redirect the user as meta-refresh can be disabled in IE.
我想出了一个比重定向用户更好的解决方案，因为可以在 IE 中禁用元刷新。
Put this in the HEAD:
把它放在 HEAD 中：
<style>div#body{display:none;}</style>
<style>div#body{display:none;}</style>
Put this in the BODY:
把它放在身体里：
<noscript>NO JAVASCRIPT CONTENT HERE</noscript>
<noscript>NO JAVASCRIPT CONTENT HERE</noscript>
<noscript><div id="body"></noscript>JAVASCRIPT CONTENT HERE<noscript></div></noscript>
<noscript><div id="body"></noscript>JAVASCRIPT CONTENT HERE<noscript></div></noscript>
That way the tags are where they're meant to be.
这样标签就在它们应该出现的地方。
