The best way of doing it is to just trigger bootstraps click event with a hover. This way, it should still remain touch device friendly 

<pre><code>$('.dropdown').hover(function(){

You can use jQuery's hover function.

You just need to add the class <code>open</code> when the mouse enters and remove the class when the mouse leaves the dropdown.

Here's my code:

<pre><code>$(function(){
 $('.dropdown').hover(function() {
 $(this).addClass('open');
 },
 function() {
 $(this).removeClass('open');
 });
});
</code></pre>

</ul>|code-block|syntax|javascript|113019|正常情况下，它在单击事件上工作，而您希望它在悬停事件上工作。这非常简单，只需使用以下javascript/jquery代码：|113020|$(document).ready(function+()+{
++++$('.dropdown-toggle').mouseover(function()+{
++++++++$('.dropdown-menu').show();

++++$('.dropdown-toggle').mouseout(function()+{

++++++++})
++++})
})|113021|这非常有效，下面是解释:我们有一个按钮和一个菜单。当我们悬停按钮时，我们显示菜单，当我们鼠标离开按钮时，我们在100毫秒后隐藏菜单。如果您想知道我为什么要使用它，是因为您需要时间将光标从按钮拖动到菜单上。当你在菜单上时，时间被重置，你可以在那里停留你想要的时间。当您退出菜单时，我们将立即隐藏菜单，而不会超时。|113022|我已经在许多项目中使用过这个代码，如果你在使用它时遇到任何问题，请随时向我提问。|113023|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

So you have this code:

<pre><code>&lt;a class="dropdown-toggle" data-toggle="dropdown"&gt;Show menu&lt;/a&gt;

&lt;ul class="dropdown-menu" role="menu"&gt;
 &lt;li&gt;Link 1&lt;/li&gt;
 &lt;li&gt;Link 2&lt;/li&gt; 
 &lt;li&gt;Link 3&lt;/li&gt; 
&lt;/ul&gt;
</code></pre>

Normally it works on click event, and you want it work on hover event. This is very simple, just use this javascript/jquery code:

<pre><code>$(document).ready(function () {
 $('.dropdown-toggle').mouseover(function() {
 $('.dropdown-menu').show();
 })

 $('.dropdown-toggle').mouseout(function() {
 t = setTimeout(function() {
 $('.dropdown-menu').hide();
 }, 100);

 $('.dropdown-menu').on('mouseenter', function() {
 $('.dropdown-menu').show();
 clearTimeout(t);
 }).on('mouseleave', function() {
 $('.dropdown-menu').hide();
 })
 })
})
</code></pre>

This works very well and here is the explanation: we have a button, and a menu. When we hover the button we display the menu, and when we mouseout of the button we hide the menu after 100ms. If you wonder why i use that, is because you need time to drag the cursor from the button over the menu. When you are on the menu, the time is reset and you can stay there as many time as you want. When you exit the menu, we will hide the menu instantly without any timeout.

I've used this code in many projects, if you encounter any problem using it, feel free to ask me questions.

This only hovers the navbar when you are not on a mobile device, because I find that hovering the navigation does not work well on mobile divices:

<pre><code> $( document ).ready(function() {

 $( 'ul.nav li.dropdown' ).hover(function() {
 // you could also use this condition: $( window ).width() &gt;= 768
 if ($('.navbar-toggle').css('display') === 'none' 
 &amp;&amp; false === ('ontouchstart' in document)) {

 $( '.dropdown-toggle', this ).trigger( 'click' );
 }
 }, function() {
 if ($('.navbar-toggle').css('display') === 'none'

 $( '.dropdown-toggle', this ).trigger( 'click' );

Triggering a <code>click</code> event with a <code>hover</code> has a small error. If <code>mouse-in</code> and then a <code>click</code> creates vice-versa effect. It <code>opens</code> when <code>mouse-out</code> and <code>close</code> when <code>mouse-in</code>. A better solution:

You implement this functionality by using Jquery:
<pre><code>$('.dropdown').on('mouseover', function(){
 $(this).addClass('show');
 $('.dropdown-menu').addClass('show');
 $('.dropdown-toggle').attr('aria-expanded', 'true');

});
$('.dropdown').on('mouseout', function(){
 $(this).removeClass('show');
 $('.dropdown-menu').removeClass('show');
 $('.dropdown-toggle').attr('aria-expanded', 'false');
});
</code></pre>

OK, so what I need is fairly straightforward.

I have set up a navbar with some dropdown menus in it (using <code>class="dropdown-toggle" data-toggle="dropdown"</code>), and it works fine.

The thing is it works "<code>onClick</code>", while I would prefer if it worked "<code>onHover</code>".

Is there any built-in way to do this?

好的，所以我需要的是相当简单的。我已经设置了一个带有一些下拉菜单的导航栏(使用class="dropdown-toggle" data-toggle="dropdown")，它工作得很好。问题是它工作"onClick"，而我更喜欢它工作"onHover“。有什么内置的方法可以做到这一点吗？
