How to set document's title per page?
提问by acmoune
I am actually using the pages/_document.jshook to add Bootstrapand jQueryto my pages, by the way I set the <Head>
我实际上是使用pages/_document.js钩子来添加Bootstrap和添加jQuery到我的页面中<Head>
export default class MyDocument extends Document {
render() {
return (
<html>
<Head>
<title>Default title</title>
<link rel="stylesheet" href="/static/lib/bootstrap3/css/bootstrap.min.css" />
</Head>
<body>
<Main/>
<NextScript/>
<script src="/static/lib/jquery3/jquery-3.3.1.min.js" />
<script src="/static/lib/bootstrap3/js/bootstrap.min.js" />
</body>
</html>
)
}
}
Now I would like to set a different Title,for my pages. Is it possible to used <Head>outside of Document? I mean in <div>like this:
现在我想为我的页面设置一个不同的标题。可以在<Head>外面使用Document吗？我的意思<div>是这样：
const ContactPage = () => {
return (
<div>
<Head>
<title>You better contact us!</title>
</Head>
<div className="page-body">...</div>
</div>
)
}
And if possible, will it overwrite or merge what is already set in pages/_document.js?
如果可能，它会覆盖或合并已经设置的内容pages/_document.js吗？

You want to use the next/headcomponent:
您要使用的next/head组件：
import Head from 'next/head'
export default () =>
<div>
<Head>
<title>My page title</title>
<meta name="viewport" content="initial-scale=1.0, width=device-width" />
</Head>
<p>Hello world!</p>
</div>
