如何在QuillJS编辑器中添加自定义字体？

.custom-font {
  font-family: 'YourCustomFont', sans-serif;
}

var quill = new Quill('#editor', {
  theme: 'snow',
  formats: {
    customFont: 'custom-font'
  }
});

quill.format('customFont', true);

var customFontButton = document.querySelector('#custom-font-button');
customFontButton.addEventListener('click', function() {
  var isActive = customFontButton.classList.contains('active');
  quill.format('customFont', !isActive);
  customFontButton.classList.toggle('active');
});
