javascript - 未捕获的 ReferenceError：deleted1 未在 HTMLButtonElement.onclick 中定义

Question

嘿，有人能帮帮我吗？我试图删除其中一行，当我已经声明了按钮时出现了下面的错误。

未捕获的 ReferenceError：deleted1 未在 HTMLButtonElement.onclick 中定义

是因为脚本类型是模块吗？有人可以帮帮我吗？

这是我的代码：

HTML

<div class="container-fluid">
        <table class="table table-bordered">
            <thead class="thead-dark">
              <th style="width: 14%;">Email</th>
              <th style="width: 23%;">Address</th>
              <th style="width: 16%;">Brought</th>
              <th style="width: 5%;">Quantity</th>
              <th style="width: 5%;">Status</th>

我不知道这对于没有 Firebase 经验的这种情况是否真的正确，但该deleted1函数应该只声明一次，并在运行时传入新值。由于似乎依赖doc于函数体中的变量，并且在构造中声明了该变量，因此向函数提供该变量的querySnapshot.forEach((doc) => {一种方法是作为参数-名称不依赖于传入的实际变量的名称，因此我叫它obj。inline在将所有 HTML 附加到文档后，您最初拥有的事件处理程序可能会替换为应用的外部事件侦听器。

// Initialize Firebase
const app = initializeApp(firebaseConfig);
const analytics = getAnalytics(app);
const firestore = getFirestore();


async function deleted1( obj, id ){
    await deleteDoc( obj( firestore, "ordered", id ) );
};
    
const querySnapshot = await getDocs(collection(firestore, "ordered"), orderBy("broughtAt"));
    querySnapshot.forEach((doc) => {
        let id = doc.id;
        let data = doc.data();

        const list = document.getElementById("tbody1");
        const row = document.createElement("tr");

        row.innerHTML += `               
            <td class="grid-item">${(data.paidby)}</td>
            <td class="grid-item">No. ${(data.numbur)}, Simpang ${(data.spg)}, Jalan ${(data.jln)}, ${(data.district)}, ${(data.code)}</td>
            <td class="grid-item">'${(data.product)}'</td>
            <td class="grid-item">${(data.amount)}</td>
            <td class="grid-item">${(data.status)}</td>
            <td class="grid-item">
                <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalCenter">Update Status</button>
                <button type="button" class="btn btn-danger btn-primary my-2 ml-2" data-id="${id}">Delete</button>
            </td>
            `;

            list.appendChild(row);
    });
    
    document.querySelectorAll('td > button.btn').forEach(bttn=>{
        bttn.addEventListener('click',function(e){
            console.log( doc, this.dataset.id )
            deleted1( doc, this.dataset.id )
        };
    })
