Question

我正在尝试使用Perfect Scrollbar与手风琴滑块菜单合作，但它没有按预期工作。请check the fiddle here

第一个子菜单的滚动条被激活，页面加载时也没有显示，但是我必须先滚动容器才能看到滚动条。

但是新的滚动条似乎没有为第二个和第三个子菜单更新。我正在尝试按照here以及使用ps.update();在互联网上的许多其他地方的建议更新PerfectScrollbar功能。不确定函数调用是否在我这里正确完成。

更新
得到它，把它留在这里，因为它可能会帮助后来的人。 https://jsfiddle.net/prashu421/egkfxzrt/

      $(document).ready(function() {
        // Store variables
        //var ps = new PerfectScrollbar('.sub-menu');

        const container = document.querySelector('.sub-menu');
        const ps = new PerfectScrollbar(container);

        var accordion_head = $('.accordion > li > a'),
            accordion_body = $('.accordion li > .sub-menu');

        // Open the first tab on load
        accordion_head.first().addClass('active').next().slideDown('normal');

        // Click function
        accordion_head.on('click', function(event) {
            // Disable header links 
            ps.update();                
            event.preventDefault();

            // Show and hide the tabs on click
            if ($(this).attr('class') != 'active'){
                accordion_body.slideUp('normal');
                $(this).next().stop(true,true).slideToggle('normal');
                accordion_head.removeClass('active');
                $(this).addClass('active');
            }
        });
    });

感谢您的考虑和帮助。谢谢。

您只将完美的滚动条应用于第一个容器元素。尝试使用querySelectorAll('.sub-menu')并将完美的滚动条应用于每个容器：

$(document).ready(function() {
  const container = document.querySelector('.sub-menu');
  document.querySelectorAll('.sub-menu').forEach(container => {
    new PerfectScrollbar(container);
  });

  const accordion_head = $('.accordion > li > a');
  const accordion_body = $('.accordion li > .sub-menu');

  // Open the first tab on load
  accordion_head.first().addClass('active').next().slideDown('normal');

  // Click function
  accordion_head.on('click', function(event) {
    // Disable header links	
    event.preventDefault();

    // Show and hide the tabs on click
    if ($(this).attr('class') != 'active') {
      accordion_body.slideUp('normal');
      $(this).next().stop(true, true).slideToggle('normal');
      accordion_head.removeClass('active');
      $(this).addClass('active');
    }
  });
});
