我想在外部JavaScript文件中添加到firebase SDK，并将我的JavaScript文件与index.html链接，我想在一个外部JavaScript文件创建所有函数，但在放入SDK代码后，我的函数无法工作，控制台中也没有输出。
//main.js 代码
import { initializeApp } from "firebase/app";
// Your web app's Firebase configuration
const firebaseConfig = {
apiKey: "AIzaSyBbXn11EFZ-B4UutkGbbvFFhddnqWFpDWc",
authDomain: "test-app-c0aed.firebaseapp.com",
projectId: "test-app-c0aed",
storageBucket: "test-app-c0aed.appspot.com",
messagingSenderId: "797893271922",
appId: "1:797893271922:web:5fc8bade62add0ca573deb"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const provider = new firebase.auth.GoogleAuthProvider();
// event and function for login button
document.getElementById('login').addEventListener("click",login);
function login()
{
console.log('login');
firebase.auth().signInWithPopup(provider).then( res => {
console.log(res);
})
}
// event and function for log out button
document.getElementById('logout').addEventListener("click",logout);
function logout(){
console.log('logout');
}
//index.html 代码

尝试添加type="模块"；编写<script type="module" src="main.js"></script>脚本并使用本地服务器托管index.html，因为当您在浏览器file://中打开index.html时，模块将不起作用
