有没有办法获取字体的下拉列表？

@font-face {
  font-family: 'CustomFont';
  src: url('path/to/font.ttf') format('truetype');
}

<select id="fontSelect">
  <option value="Arial">Arial</option>
  <option value="CustomFont">Custom Font</option>
  <!-- 其他字体选项 -->
</select>

var fontSelect = document.getElementById('fontSelect');
var selectedFont = fontSelect.options[fontSelect.selectedIndex].value;

var targetElement = document.getElementById('targetElement');
targetElement.style.fontFamily = selectedFont;
