如何获取以某些东西开头的所有HTML属性(属性名称,*不是*它们的值!)

function getAttributesStartingWith(prefix) {
  const result = [];
  const elements = document.getElementsByTagName('*');

  for (const element of elements) {
    for (const attribute of element.attributes) {
      if (attribute.name.startsWith(prefix)) {
        result.push(attribute.name);
      }
    }
  }

  return result;
}

// 示例用法
const attributesStartingWithData = getAttributesStartingWith('data-');
console.log(attributesStartingWithData);
