Question

const list = document.querySelector('#book');
const row = document.createElement('tr');

>     row.innerHTML ='
>     <td>${book.title}</td>
>     <td>${book.author}</td>
>     <td>${book.number}</td>
>     <td><a href="#" class="btn btn-danger btn-smdelete">X</a></td>
>                     ';

list.appendChild(row);

问题是为什么我不能使用该方法在 tr 中添加多个 td ，但出现错误，如何解决？我知道使用insertRow() then create insertCell()的另一种方法，但我不想使用它。

Answer 1

var books = [{
  title: "IT",
  author: "Stephen King",
  number: "0987654321"
}, {
  title: "Pet Sematary",
  author: "Stephen King",
  number: "1234567890"
}]

const list = document.querySelector('#book');

books.forEach(function(book) {
  const row = document.createElement('tr');
  const tdBook = document.createElement('td');
  const tdAuthor = document.createElement('td');
  const tdNumber = document.createElement('td');
  const tdLink = document.createElement('a');

  tdBook.innerText = book.title;
  tdAuthor.innerText = book.author;
  tdNumber.innerText = book.number;
  tdLink.href = "#";
  tdLink.classname = "btn btn-danger btn-smdelete";
  tdLink.innerText = "X";

  row.appendChild(tdBook);
  row.appendChild(tdAuthor);
  row.appendChild(tdNumber);
  row.appendChild(tdLink);

  list.appendChild(row);
});

<table id="book">

</table>
