Question

我正在尝试使用以下属性创建手风琴导航菜单：

将鼠标悬停在父LI上，其子菜单向下滑动。如果您将鼠标按下鼠标悬停在子菜单上，它将保持打开状态。

如果将光标从父链接或子菜单移开，子菜单会再次向上滑动。

我以为我越来越近了 - 我可以将子菜单设置为slideDown，但是当我将鼠标悬停在它上面时，我不得不在父LI上鼠标移动，触发一个slideUp。我只是无法弄清楚如何做到这一点我需要它！

这是我的剧本：

<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：

我真的感谢任何帮助，拜托！

Answer 1

好的，谢谢任何看过的人。我现在已经设法解决了这个问题。我用以下代码替换了包含 mouseover 和 mouseout 的jQuery块：

$("#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
}
);

如果你在它上面来回运行光标，它会有点生涩，但它至少有效。我想尽可能正确地停止动画队列。

我建议使用jQuery UI的精彩手风琴（带悬停功能）：http://jqueryui.com/demos/accordion/#hoverintent

Answer 3

不确定页面上的内容是什么，但这似乎适用于您提供的代码。现在已经很晚了，没有经过全面测试，但是给出了一个镜头：

// 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");
});

还要确保摆脱鼠标输出代码

Answer 4

我知道这是一个老帖子，但我想我会为寻求帮助的其他人做出贡献。你真的应该使用.on（）事件处理程序而不是.hover（）用于新版本的jQuery。以下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);
    }

});
