使用jQuery在鼠标悬停时显示/隐藏下拉菜单 [英] show/hide dropdown menu on hover/mouseout using jquery

问题描述

因此，当用户将鼠标悬停在更多"选项卡上时，我有一个带有下拉菜单的简单导航栏.当用户将鼠标从div类别中移出时，我想隐藏下拉菜单.

so i have a simple navbar with a dropdown menu for when a user hovers on the more tab. i want to hide the dropdown menu when the user mouses out of the categories div.

问题是，当用户将鼠标悬停在所有菜单上时，下拉菜单将关闭.我如何设置它，以便函数忽略类别div中的ul.尝试了类别> *，但没有用.

problem is that when the user mouses into a ul li, the dropdown closes. how can i set it so that the function ignores the ul li within the categories div. tried categories > * but didn't work.

<div id="navbar">
  <ul>
    <li>tab1</li>
    <li>tab2</li>
    <li id="moretab">more</li>
  </ul>
</div> 
<div id="categories">
  <ul>
    <li>cats</li>
    <li>dogs</li>
  </ul>
</div>

$("#moretab").hover(function(){
  $("#categories").css("visibility","visible"); 
});
$("#categories").mouseout(function() {
    $("#categories").css("visibility","hidden"); 
});

推荐答案

最简单的答案是在没有jQuery的情况下如何做:将下拉列表放到触发元素中(例如，下拉列表位于导航列表中的列表项中).

The easiest answer is how you would do it without jQuery: put the dropdown in the triggering element (e.g. dropdown list in a list item in the navigation list).

如果您想要简单一些的内容，mouseleave可能会有所帮助.

If you want something less straightforward, mouseleave might help.
