Php Superfish：单击子菜单后如何保持其打开状态

我有下面的场景。我有一个菜单，如果鼠标悬停在菜单上，就会出现一个子菜单，如果鼠标移出子菜单，子菜单就会消失，现在我想要下面的内容如果我点击子菜单中的某个项目，我想要在加载新页面时子菜单保持打开状态。我正在使用superfish Jquery插件来实现这一点

这有可能吗？如果有，怎么办

我的html代码

<div id="nav">
        <div id="nav2">
            <ul class="sf-menu sf-navbar ">
                <li>
                                        <a title="HOME" class="sf-with-ul " href="/index.php?r=site/index&amp;sid=1">HOME</a>               </li>   
            </ul>
            <ul class="sf-menu sf-navbar">
                <li>

                    <a href="?sid=2" id="gallery" class="sf-with-ul selected_main">GALLERY</a>
                    <ul class="subs" id="sub1"><li class="arrow"><img src="images/arrow.gif" /></li><li><a title="Kitchens" href="/index.php?r=images/sddsd&amp;id=1">Kitchens</a></li><li><a title="Vanities" href="/index.php?r=images/sddsd&amp;id=2">Vanities</a></li></ul>             </li>    
            </ul>
            <ul class="sf-menu sf-navbar ">
                <li>
                    <a href="?sid=3" class="sf-with-ul " >ACCESSORIES</a>
                                        <ul class="subs" id=""><li class="arrow"><img src="images/arrow.gif" /></li><li><a title="Door Handles" href="/index.php?r=images/sddsd&amp;id=2">Door Handles</a></li><li><a title="Spanners" href="/index.php?r=images/sddsd&amp;id=1">Spanners</a></li></ul>             </li>   
            </ul>

            <ul class="sf-menu sf-navbar ">
                <li>
                                        <a title="CONTACT US" class="sf-with-ul " href="/index.php?r=site/contact&amp;sid=4">CONTACT US</a>             </li>   
            </ul>   
        </div>

</div>

我还注意到以下css代码用于显示该项

left:   0;
top:    2.5em;
z-index:        99;

我替你发帖。基本上，我已经在superfish函数中添加了一个“onHide”函数，然后添加了一些额外的代码来保持菜单的持久性

附加CSS（默认为suckerfish.CSS）

剧本

$(function(){
    var menu = $("#nav");

    menu.find("ul.sf-menu")
        .superfish({
            delay:         0,
            speed:         'fast',
            autoArrows:    false,
            dropShadows:   false,
            onHide:        function(){
                if (this.parent().is('.sfPersist')) {
                    this.show().css('visibility','visible').parent().addClass('sfHover');
                }
            }
        })
        .find('li > ul > li').click(function(){
            // hide previously persistent children (LOL that just sounds wrong)
            menu.find('.sfPersist')
                .removeClass('sfPersist sfHover')
                .find('> ul').hide().css('visibility','hidden');

            // add children that should be persistent
            if ($(this).is('.sfSelected')) {
                // if previously selected, keep hidden
                menu.find('li.sfSelected').removeClass('sfSelected');
            } else {
                // Hide other selected classes
                menu.find('li.sfSelected').removeClass('sfSelected');
                // if newly selected, then show
                $(this)
                    .addClass('sfSelected') // remember which one is selected
                    .parent()
                    .show().css('visibility','visible')
                    .parent().addClass('sfHover sfPersist');
            }
        });
});

完美的这很有效。我正在使用Drupal库。我只是将脚本粘贴到superfish.js中，没有使用函数包装器，效果非常好。感谢您发布此解决方案。

.sf-menu li.sfSelected {
 background-color: #CFDEFF;
}

$(function(){
    var menu = $("#nav");

    menu.find("ul.sf-menu")
        .superfish({
            delay:         0,
            speed:         'fast',
            autoArrows:    false,
            dropShadows:   false,
            onHide:        function(){
                if (this.parent().is('.sfPersist')) {
                    this.show().css('visibility','visible').parent().addClass('sfHover');
                }
            }
        })
        .find('li > ul > li').click(function(){
            // hide previously persistent children (LOL that just sounds wrong)
            menu.find('.sfPersist')
                .removeClass('sfPersist sfHover')
                .find('> ul').hide().css('visibility','hidden');

            // add children that should be persistent
            if ($(this).is('.sfSelected')) {
                // if previously selected, keep hidden
                menu.find('li.sfSelected').removeClass('sfSelected');
            } else {
                // Hide other selected classes
                menu.find('li.sfSelected').removeClass('sfSelected');
                // if newly selected, then show
                $(this)
                    .addClass('sfSelected') // remember which one is selected
                    .parent()
                    .show().css('visibility','visible')
                    .parent().addClass('sfHover sfPersist');
            }
        });
});
