如何在代码中导入lit-html? 我有以下代码:
index.js
文件夹中的js
文件:
import { html } from "lit-html";
myDiv = html`
<div>
<a href="">Hello, Click Me!</a>
</div>
`;
document.body.innerHTML += myDiv;
和index.html
文件:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>JS Tests</title>
</head>
<body>
<script type="module" src="js/index.js"></script>
</body>
</html>
我收到这样的错误:
Uncaught TypeError: Failed to resolve module specifier "lit-html". Relative references must start with either "/", "./", or "../".

您可以尝试
import {render, html } from "https://unpkg.com/lit-html@0.7.1/lit-html.js"
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>JS Tests</title>
</head>
<body>
<script type="module" src="js/index.js"></script>
</body>
</html>
JS
import {render, html } from "https://unpkg.com/lit-html@0.7.1/lit-html.js";
const myDiv = html`
<div>
<a href="">Hello, Click Me!</a>
</div>
`;
render(myDiv,document.body);
请注意,如果您正在浏览器上使用模块(如上述),则每次导入都会进行网络调用。在将代码交付给浏览器之前,您可以使用诸如webpack之类的模块捆绑器来构建单个JS文件(具有所有依赖项)。
