Question

我的标题出现问题，当我在移动设备上打开此网站并单击“汉堡”按钮时，导航菜单根本无法响应。菜单位于“位置：固定”，根据移动设备的不同，我需要更改“顶部：n％”，因此我不知道该如何响应。

Answer 1

如果我了解您要做什么，您可以将菜单类从position: fixed;更改为position: absolute;并将top: 97%设置为所有介质尺寸，因此您应该： >

    const ipad = window.matchMedia('screen and (max-width: 658px)');
    const menu = document.querySelector('.menu');
    const burgerButton = document.querySelector('#burger-menu');
    
    ipad.addListener(validation)
    
    function validation(event) {
      if (event.matches) {
        burgerButton.addEventListener('click', hideShow);
      } else {
        burgerButton.removeEventListener('click', hideShow);
      }
    }
    
    validation(ipad);
    
    function hideShow() {
      if (menu.classList.contains('is-active')) {
        menu.classList.remove('is-active');
      } else {
    
        menu.classList.add('is-active');
    
      }
    }
