Next.js - 如何添加 <link><head> 内的标签带有文字 onload 属性字符串值? [英] Next.js - How to add a <link> tag inside the <head> with literal onload attribute string value?
问题描述
在 Next.js 项目中，我想在 <head> 中获得一些具有完全相同内容的初始 HTML:
在 Next.js 的 <Head> 组件中，我的代码中有:
{/* @ts-ignore */}<link href="...";rel=样式表"媒体=打印"onload="this.media='all'";/>没有 @ts-ignore 它说:
属性onload"在类型DetailedHTMLProps
如果我使用 onLoad 而不是 onload 我得到:
类型 'string' 不可分配给类型 '(event: SyntheticEvent
问题是我得到的服务器端生成的 HTML 有:
并且只有在页面重新水化后，它才会更新为:
我在 GitHub 上发现了这个问题，但它没有帮助，因为我使用的不是 Google 字体而是 Typography.com，所以我无法使用 next-google-fonts:https://github.com/vercel/next.js/issues/12984
我正在考虑将 ref 添加到该 link 标记并使用 setAttribute 设置属性，这有望在服务器上运行-side 也是如此，但想知道是否有更简单的方法来做到这一点.
所以我最终使用 <style> 标签和 dangerouslySetInnerHTML 在 自定义 _document.js.总的来说，它应该是这样的:
生成以下输出:
<link rel=预加载"href=https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap"as=风格"/><style></style><link rel="样式表";href=https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap"媒体=打印"onload="this.media='all';"/><style></style><noscript><link rel="stylesheet";类型=文本/css"；href=https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap"/></noscript>不漂亮，但比在 中包含
有一个 开放 RFC 来创建一个 RawHTML组件或扩展 Fragment 以接受 dangerouslySetInnerHTML 以便这样的事情在没有黑客的情况下是可能的，但它自创建以来已经一年多了.
此外，还有对此进行了相当长的讨论以及一些不同的似乎有效的解决方案(黑客).

On a Next.js project, I'd like to get some initial HTML with this exact same content inside the <head>:
<link href="..." rel="stylesheet" media="print" onload="this.media='all'" />
What I have in my code, inside Next.js's <Head> component, is:
{ /* @ts-ignore */ }
<link href="..." rel="stylesheet" media="print" onload="this.media='all'" />
Without the @ts-ignore it says:
Property 'onload' does not exist on type 'DetailedHTMLProps<LinkHTMLAttributes, HTMLLinkElement>'. Did you mean 'onLoad'? ts(2322)
And if I use onLoad instead of onload I get:
Type 'string' is not assignable to type '(event: SyntheticEvent<HTMLLinkElement, Event>) => void'. ts(2322)
The problem is that the server-side generated HTML that I get has:
<link href="..." rel="stylesheet" media="print" />
And only once the page has rehydrated it updates to:
<link href="..." rel="stylesheet" media="all" onload="this.media='all'">
I've found this issue on GitHub but it doesn't help as I'm not using Google Fonts but Typography.com, so I can't use next-google-fonts: https://github.com/vercel/next.js/issues/12984
I'm thinking about adding a ref to that link tag and setting the attribute using setAttribute, which will hopefully work on the server-side as well, but wondering if there's a simpler way to do it.
So I eventually fixed this using a <style> tag with dangerouslySetInnerHTML in a custom _document.js. All together it should look like this:
<link rel="preconnect" href="https://fonts.googleapis.com" crossOrigin="anonymous" />
<link rel="preload" href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap" as="style" />
<style dangerouslySetInnerHTML={ {
__html: `</style>
<link
rel="stylesheet"
href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap"
media="print"
onload="this.media='all';"
/>
<style>`
} }></style>
<noscript>
<link
rel="stylesheet"
type="text/css"
href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap" />
</noscript>
Which generates the following output:
<link rel="preconnect" href="https://fonts.googleapis.com" crossorigin="anonymous"/>
<link rel="preload" href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap" as="style"/>
<style></style>
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap" media="print" onload="this.media='all';" />
<style></style>
<noscript><link rel="stylesheet" type="text/css" href="https://fonts.googleapis.com/css2?family=Inconsolata:wght@400;600&family=Karla:wght@700&display=swap"/></noscript>
Not pretty, but better than having a <div> inside the <head> (which is not interpreted correctly by all browsers).
There's an open RFC to create a RawHTML component or extend Fragment to accept dangerouslySetInnerHTML so that something like this is possible without hacks, but it's been more than a year since it was created.
Also, there's quite a long discussion about this as well with a few different solutions (hacks) that seem to work.
