Next.JS implement external ".js" with <script>
Im Building a website with Next.Js and I tried to implement an external .js file (Bootstrap.min.js & Popper.min.js) but it is not displayed. Im not sure what the problem is!
I implemented it like this:
It looks good to me? what am I missing, it's not projecting as it should!
When I tried a script inside the page it shows "Hello JavaScript" for a very short time and then it disappears?
<p id="demo"></p>
<script>document.getElementById("demo").innerHTML = "Hello JavaScript";</script>How do i fix it?
Please help!
Im Using: "next": "^8.0.3", "react": "^16.8.4", "react-dom": "^16.8.4"
Answer
- You need to put all your scripts inside the
Headtag. - Don't put raw javascript inside the
Headtag. Put it in a separate file and import the script in theHeadtag
You can create a .js file, which contains your raw js code, in the public folder and then use the script in the Head tag. I am not sure why we have to do this, but this is how it works in Next.js
So for your problem, this will work:
public/js/myscript.js
document.getElementById("demo").innerHTML = "Hello JavaScript";
Layout.js
import Head from 'next/head';
const Layout = (props) => (
<div>
<Head>
{/* import external javascript */}
<script type="text/javascript" src="..."></script>
<script type="text/javascript" src="/js/myscript.js"></script>
</Head>
<p id="demo"></p>
</div>
);
export default Layout;
