Why can't my HTML file find the JavaScript function from a sourced module?
This may happen if you haven’t used “export” statement. Use “export” before the function which
will be imported into the script file. The JavaScript file is as follows which has the file name
demo.js.
demo.js
console.log("function will import");
export function test(){
console.log("Imported!!!");
}Here is the “index.html” file that imports the above function −
index.html
Example
Live Demo
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<script type='module'>
import { test } from "./demo.js"
test();
</script>
</body>
</html>To run the above program, save the file name “anyName.html(index.html)” and right click on the
file. Select the option “Open with Live Server” in VS Code editor.
Following is the output from the file demo.js which has the function name test().
