Question

任何人都可以告诉我我的下拉菜单出了什么问题吗？当我将鼠标移离'WEDDINGS'时，它需要关闭，但只有当我将鼠标从顶部菜单移开时它才会关闭。

非常感谢任何帮助。

        //Following events are applied to the subnav itself (moving subnav up and down)

Answer 1

我知道你要做什么，我在这里告诉你，你这样做的方式是完全错误。我尝试使用你的代码，但这不是一个可行的选择;相反，我所做的是花时间做一个jsfiddle示例，其中有一个“裸露”的工作示例，说明如何使用jQuery实现下拉导航。

调查一下。

Answer 2

$(document).ready(function(){
    $("ul.topnav li.ddmhover").hover(function() { //When trigger is hovered...

        //Following events are applied to the subnav itself (moving subnav up and down)
        $(this).parent().find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on hover

        // Right here you are attaching to .ddmhover's parent ".topnav",
        // not .ddmhover, so it is sliding up when you mouseOut of ".topnav"
        // This should be in a function that is a second parameter to your first
        // .hover() call instead of this...
        $(this).parent().hover(function() {
        }, function(){
            $(this).parent().find("ul.subnav").slideUp('slow').stop(true,true); //When the mouse hovers out of the subnav, move it back up
        });
        //Following events are applied to the trigger (Hover events for the trigger)
        }).hover(function() {
            $(this).addClass("subhover"); //On hover over, add class "subhover"
        }, function(){  //On Hover Out
            $(this).removeClass("subhover"); //On hover out, remove class "subhover"
});

<强>更新

我把它重写为更广泛的。这样，您不需要为您创建的每个下拉列表和子窗口都有单独的类名。相反，你只需使用“.ddmhover”和“.subnav”。

$(document).ready(function(){
    $("li.ddmhover").mouseover(function() {
        var that = this,
        subnav = $(this).find("ul.subnav"),
        img = $(this).find('img'),
        subnavTimeout;

        $(this).addClass("subhover");
        subnav.slideDown('fast');

        var hideSubnav = function (evt) {
            // Wait half a second before trying to hide subnav
            subnavTimeout = setTimeout( function () {
                $(subnav).unbind('mouseleave');
                $(subnav).slideUp('slow');
                $(that).removeClass("subhover");
            }, 500);
        };

        $(subnav).mouseleave(hideSubnav)
        // since the title image fills the whole .ddmhover li we must attach to the image itself
        $(img).mouseleave(hideSubnav);

        // If the mouse entered the subnav don't close the subnav
        $(subnav).mouseenter(function () {
            clearTimeout(subnavTimeout);
        });
    });
});

我们都会不时地这样做，但每当你发现自己复制/粘贴一大块代码然后改变一个或两个字符串时，最好创建一个处理它的通用方法。
