document.addEventListener('DOMContentLoaded', function() {

  const tabPanes = document.querySelectorAll('.tab-pane');

  tabButtons.forEach(button => {
    button.addEventListener('click', function() {
      const targetTab = this.getAttribute('data-tab');

      // 移除所有按钮的active类
      tabButtons.forEach(btn => btn.classList.remove('active'));
      // 添加当前按钮的active类
      this.classList.add('active');

      // 隐藏所有内容面板
      tabPanes.forEach(pane => pane.classList.remove('active'));
      // 显示目标内容面板
      document.getElementById(targetTab).classList.add('active');
