Answer 1

来自bootstrap-docs：

$('#flatmenu').on('shown.bs.dropdown hidden.bs.dropdown', function () {
  $('.show-me').toggle('slow');
});

Demo

Answer 2

您可以对即将 show/hide 的 div 执行 .click() for the element that it's intended for and use the .toggle() 效果。

代码片段：

$("#flatmenu").click(function () {
    $('.show-me').toggle('slow');
});

Answer 3

你可以试试这个更新后的fiddle

代码：

$('#flatmenu').on('click',function(){
    $this = $(this);
    setTimeout(function(){
        if($this.hasClass('open')){
            $('.show-me').show('slow');
        }else{
            $('.show-me').hide('slow');
        }
    },100);
});
