回到手风琴标题处。

jquerycssaccordion

我发现了一个手风琴，原链接在这里

我的需求是：当我从手风琴的中部点击时，它应该自动滚动到顶部。目前它停留在点击处。 以下是代码：

var accordion = (function(){
  
  var $accordion = $('.js-accordion');
  var $accordion_header = $accordion.find('.js-accordion-header');
  var $accordion_item = $('.js-accordion-item');
 
  // default settings 
  var settings = {
    // animation speed
    speed: 400,
    
    // close all other accordion items if true
    oneOpen: false
  };
    
  return {
    // pass configurable object literal
    init: function($settings) {
      $accordion_header.on('click', function() {
        accordion.toggle($(this));
      });
      
      $.extend(settings, $settings); 
      
      // ensure only one accordion is active if oneOpen is true
      if(settings.oneOpen && $('.js-accordion-item.active').length > 1) {
        $('.js-accordion-item.active:not(:first)').removeClass('active');
      }
      
      // reveal the active accordion bodies
      $('.js-accordion-item.active').find('> .js-accordion-body').show();
    },
    toggle: function($this) {
            
      if(settings.oneOpen && $this[0] != $this.closest('.js-accordion').find('> .js-accordion-item.active > .js-accordion-header')[0]) {
        $this.closest('.js-accordion')
               .find('> .js-accordion-item') 
               .removeClass('active')
               .find('.js-accordion-body')
               .slideUp()
      }
      
      // show/hide the clicked accordion item
      $this.closest('.js-accordion-item').toggleClass('active');
      $this.next().stop().slideToggle(settings.speed);
    }
  }
})();

$(document).ready(function(){
  accordion.init({ speed: 300, oneOpen: true });
});

所以，当用户点击手风琴时，它应该自动向上移动。有人可以帮忙吗？我尝试了一些脚本，但似乎没有起作用。

您可以在点击事件中添加以下代码：

$('body, html').animate({
    scrollTop: $(this).offset().top
}, 500);

找到这段代码。
$accordion_header.on('click', function() {
   accordion.toggle($(this));
});

将其更改为，并将您滚动到手风琴头部的顶部。

$accordion_header.on('click', function() {
  accordion.toggle($(this));
        
  setTimeout(() => {
    $('body, html').animate({
      scrollTop: $(this).offset().top
     }, 500)
  }, 400)
});

你可以在这个codepen上查看。

是的，在打开手风琴时计算偏移量顶部存在问题。您可以使用插件速度属性添加setTimeout来解决此问题。我已经更新了答案，加入了setTimeout。 - Rado
