如何根据数据动态添加字体图标

@font-face {
  font-family: 'FontAwesome';
  src: url('path/to/font-awesome/fontawesome-webfont.eot');
  src: url('path/to/font-awesome/fontawesome-webfont.eot?#iefix') format('embedded-opentype'),
       url('path/to/font-awesome/fontawesome-webfont.woff2') format('woff2'),
       url('path/to/font-awesome/fontawesome-webfont.woff') format('woff'),
       url('path/to/font-awesome/fontawesome-webfont.ttf') format('truetype'),
       url('path/to/font-awesome/fontawesome-webfont.svg#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

// 获取数据
const icon = data.icon;
// 动态添加字体图标
const iconElement = document.createElement('i');
iconElement.classList.add('fa', `fa-${icon}`);
// 将图标元素添加到页面中
document.body.appendChild(iconElement);
