一般情况下js的module需要通过type=“module”引入，还可直接在js代码中import * from ‘./module.js’,当然将module写在调用的js代码一块的话就不需要import了，示例代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>JavaScript Modules</title>
</head>
<body>
<h1>Answers</h1>
<h2><strong id="x"></strong> and <strong id="y"></strong></h2>
<h3>Addition</h3>
<p id="addition"></p>
<h3>Subtraction</h3>
<p id="subtraction"></p>
<h3>Multiplication</h3>
<p id="multiplication"></p>
<h3>Division</h3>
<p id="division"></p>
<script type="module" >
export function sum(x, y) {
return x + y
}
export function difference(x, y) {
return x - y
}
export function product(x, y) {
return x * y
}
export function quotient(x, y) {
return x / y
}
const x = 10
const y = 5
document.getElementById('x').textContent = x
document.getElementById('y').textContent = y
document.getElementById('addition').textContent = sum(x, y)
document.getElementById('subtraction').textContent = difference(x, y)
document.getElementById('multiplication').textContent = product(x, y)
document.getElementById('division').textContent = quotient(x, y)
</script>
</body>
</html>
