为什么我的jQuery菜单在点击链接之前消失？(Why does my jQuery menu disappear before I click a link?)

我在写一个jQuery下拉菜单。我将鼠标悬停在链接上，菜单应该出现......并且确实如此。问题是在我进入菜单链接之前菜单关闭了。除非鼠标离开菜单或顶级链接，否则菜单不应该消失。我应该这样做吗？

$(function(){ //Find all ul elements within items in the nav $('nav ul li:has(ul)').each(function(){ //Prevent the links that have submenus from being clicked $(this).children('a').on('click', function(e){ e.preventDefault(); }); $(this).children('a').mouseover(function(){ console.log('hovered'); $(this).parent().find('ul').css('display', 'inline'); }) .mouseout(function(){ $(this).parent().find('ul').css('display', 'none'); }); }); });

这是一个jsFiddle

I am writing a jQuery dropdown menu. I hover over a link and a menu is supposed to appear... and does. The problem is that the menu closes before I get to a menu link. The menu should not disappear unless the mouse leaves the menu or the top level link. Should I be doing this differently?

$(function(){ //Find all ul elements within items in the nav $('nav ul li:has(ul)').each(function(){ //Prevent the links that have submenus from being clicked $(this).children('a').on('click', function(e){ e.preventDefault(); }); $(this).children('a').mouseover(function(){ console.log('hovered'); $(this).parent().find('ul').css('display', 'inline'); }) .mouseout(function(){ $(this).parent().find('ul').css('display', 'none'); }); }); });

最满意答案

这是因为mouseover id绑定到了锚元素，并且ul不是它的子元素，所以当你移动到子菜单时它会关闭。

将您的选择器更改为：

$(this).mouseover(function(){ console.log('hovered'); $(this).parent().find('ul').css('display', 'inline'); }) .mouseout(function(){ $(this).parent().find('ul').css('display', 'none'); });

并会正常工作。

It's because the mouseover id bound to the anchor element, and the ul is not a children of it, so when you move to the submenu it closes.

Change your selector to:

$(this).mouseover(function(){ console.log('hovered'); $(this).parent().find('ul').css('display', 'inline'); }) .mouseout(function(){ $(this).parent().find('ul').css('display', 'none'); });

and will work fine.
