如何清除 HTML 标签中的所有属性，并保留表格结构？

function removeAttributes(htmlString) {
  var pattern = /<[^>]+?(\s+[^>]*?)?>/gi;
  var cleanString = htmlString.replace(pattern, function (match) {
    return match.replace(/(\s+\w+(=["'][^"']*["'])?)/gi, '');
  });
  return cleanString;
}

// 示例用法
var htmlString = '<p class="my-class" style="color:red">This is a paragraph.</p>';
var cleanedString = removeAttributes(htmlString);
console.log(cleanedString); // <p>This is a paragraph.</p>
