我有一个下拉菜单,可以在点击时展开而不是悬停。问题是当我打开子菜单时,当我将鼠标从当前子菜单移动到它的父菜单时,我无法关闭它们。一旦我离开它的任何子菜单并将鼠标悬停在页面主体上,它应该一直隐藏上一个菜单直到导航栏(顶部)并隐藏所有菜单。

                $('ul:first', this).show();
            });
        });

    var submenu_active = false;
     $('#menuJQ ul').mouseenter(function() {
        submenu_active = true;      
     });

    $('#menuJQ ul').mouseleave(function() {
        submenu_active = false;
        setTimeout(function() { 
            if (submenu_active === false) $('ul', this).hide("fast");});

我会给div包含任何子菜单的 s 一个类,例如submenu

 ...
 <li><a href="#" class="parent"><span>Search</span></a>
     <div id="submenu">
        <ul>
           ...

然后你可以做这样的事情:

$(document).ready(function(){
    $(function() {
            $('#menuJQ > ul li').click(function(e) {
                e.preventDefault();
                $('ul:first', this).show();
            });
        });

    $('.submenu').mouseleave(function() {
        $('ul', this).hide("fast");
    });
});
