将鼠标悬停在子菜单上后突出显示父菜单项(HTML/CSS/Jquery)

Question

我有一个菜单,有些菜单项可能有子项.实际上非常简单.我希望实现这一点,一旦子菜单被鼠标滑过,相应的(父)菜单项也会突出显示.这种情况从未发生过,因为似乎只要鼠标离开菜单项并越过子菜单,浏览器就会将其设置为默认样式.任何帮助赞赏!非常感谢!

菜单html:

<div id="top_navigation">
        <ul>
            <li><a href="#">item1</a></li>
            <li><a href="#">item2</a>
                <ul class="submenu">
                    <li><a href="#">sub1</a></li>
                    <li><a href="#">sub2</a></li>
                    <li class="selected_menu_item"><a href="#">sub3</a></li>
                </ul>
            </li>
            <li><a href="#">item3</a></li>
            <li><a href="#">item4</a></li>
        </ul>
    </div>

CSS:

#top_navigation {
    width: 1248px;
    margin: 0 auto;
    position: relative;
    text-transform: uppercase;
    font-family: "Rounded Font", sans-serif;
    font-size: 23px;
}
#top_navigation ul ul {
    display: none;
}
#top_navigation ul {
    padding-left: 0;
}
#top_navigation ul li {
    margin: 0;
    padding: 0;
    float: left;
    width: 312px;
    height: 64px;
    line-height: 64px;
    font-size: 20px;
    list-style: none;
}
#top_navigation ul li a {
    display: block;
    text-align: center;
    text-decoration: none;
    color: #eb1f10;
    background-color: #FFF;
}
#top_navigation ul li.selected_menu_item a {
    background-color: #eb1f10;
    color: #FFF;
}
#top_navigation ul li a:hover {
    background-color: #eb1f10;
    color: #FFF;
}
#top_navigation li li {
    height: 42px;
    line-height: 42px;
    border-top: #eb1f10 1px solid;
}

JS/jQuery的:

$(document).ready(function () {
    var $nav = $('#top_navigation > ul > li');
    $nav.hover(
        function() {
            $('ul', this).stop(true, true).slideDown('fast');
        },
        function() {
            $('ul', this).slideUp('fast');
        }
    );
});

哦,现在我不知道以前怎么没发生过......我会回答的:

交换它就足够了:

#top_navigation ul li a:hover {
    background-color: #eb1f10;
    color: #FFF;
}

为了这:

#top_navigation ul li:hover > a {
    background-color: #eb1f10;
    color: #FFF;
}
