我正在尝试创建具有以下属性的手风琴导航菜单:

将鼠标悬停在父 LI 上,其子菜单会向下滑动。如果您将鼠标向下悬停在子菜单上,它会按照您的预期保持打开状态。

如果您将光标从父链接或子菜单上移开,子菜单会再次向上滑动。

我以为我快要接近了——我可以让子菜单滑下,但是当我将鼠标悬停在它上面时,我不得不将鼠标悬停在父 LI 上,从而触发了上滑。我只是不知道如何让它做我需要的!

这是我的脚本:

<script type="text/javascript">

$(document).ready(function() {

//If its a page parent (based off wordpress), add the class "display-list"
//This way the accordion will be opened up on the page you are on.
if ($('#nav li').hasClass("current_page_parent")) {
$('#nav .current_page_parent ul').addClass("display-list"); }

// Hide the submenus
$('#nav li ul').hide();
// Add a class to the parent li IF it has sub UL's
$("#nav li:has(ul)").addClass("nav-parent");
// Add a class to sub-UL if it has a parent LI
$("#nav li ul").addClass("nav-child");

// When you hover over the link in the parent LI...
$('#nav li.nav-parent').mouseover( function() {
// ...slide the sub-UL into view, and remove the 'display-list' class
$(this).children('.nav-child').slideDown(1000).removeClass("display-list");
}).mouseout( function() {
$(this).children('.nav-child').slideUp(1000);
});

});
</script>

这是我的 HTML 标记:

好的,感谢任何看过的人。我现在几乎设法解决了这个问题。我已将包含mouseovermouseout的 jQuery 块替换为:

$("#nav li.nav-parent").hover(
function () { 
$(this).children('.nav-child').stop(true,true).slideDown(1000).removeClass("display-list"); // fired on mouseover
},
function () {
$(this).children('.nav-child').slideUp(1000); // fired on mouseout
}
);

如果您在它上面来回运行光标,这会有点生涩,但它至少可以工作。如果可能的话,我想正确地停止动画队列。

我建议使用 jQuery UI 的出色手风琴(具有悬停功能):http: //jqueryui.com/demos/accordion/#hoverintent

不确定您页面上的所有内容,但这似乎适用于您提供的代码。已经很晚了,还没有完全测试,但试一试:

// When you hover over the link in the parent LI...
$('#nav li.nav-parent').mouseover( function() {
self = this;
// ...slide the sub-UL into view, and remove the 'display-list' class
$('#nav li.nav-parent').each(function(){if(self != this)$(this).children('.nav-child').slideUp(1000)});
$(this).children('.nav-child').slideDown(1000).removeClass("display-list");
});

还要确保摆脱你的 mouseout 代码

我知道这是一篇旧帖子,但我想我会为其他寻求帮助的人做出贡献。对于新版本的 jQuery,您确实应该使用 .on() 事件处理程序而不是 .hover() 。这是我在网站上使用的示例...

$('.leftnav-item:not(.active)').on({

    mouseenter: function() {
        $(this).find('.nav-sublock').stop(true,true).slideDown(500);
    },

    mouseleave: function() {
        $(this).find('.nav-sublock').slideUp(500);
    }

});
