我正在尝试从API中提取7种产品，并在DOM中显示它们。当我尝试为每个产品创建一个div并将其插入HTML时，我得到一个div，其中包含“ 、、、、、、、”。由于我能够从API控制台记录数据，因此该请求正在运行。
const results = document.getElementById('result');
fetch('http://localhost:1337/products')
.then(response => response.json())
.then((data) =>{
results.innerHTML = data.map(product =>{
console.log(product.meal);
`
<div class="result">
<h3>${product.meal}</h3>
<p>${product.description}</p>
<p>${product.price}</p>
</div>
`
})

data.forEach(product => {
console.log(product.meal);
results.innerHTML += `
<div class="result">
<h3>${product.meal}</h3>
<p>${product.description}</p>
<p>${product.price}</p>
</div>`
})您需要return功能内的值。 map将返回具有修改后值的新数组。
