如何向列表中添加的每个li元素添加一个删除按钮？

var liElements = document.querySelectorAll('li');

liElements.forEach(function(li) {
  var deleteButton = document.createElement('button');
  deleteButton.textContent = '删除';
  li.appendChild(deleteButton);
});

liElements.forEach(function(li) {
  var deleteButton = document.createElement('button');
  deleteButton.textContent = '删除';
  li.appendChild(deleteButton);
  
  deleteButton.addEventListener('click', function() {
    li.remove();
  });
});
