Bootstrap 3 Hide Dropdown Menu on Menu Item Click
提问by dougmacklin
Check out the fiddle. I have a basic Bootstrap 3 responsive nav like so:
检查小提琴。我有一个基本的 Bootstrap 3 响应式导航，如下所示：
<div id="navbar" class="navbar navbar-fixed-top navbar-inverse">
<div class="container">
<a id="navbar-toggle" class="navbar-toggle" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="navbar-brand" href="#">Title Title Title</a>
<div id="nav-collapse" class="nav-collapse collapse">
<ul class="nav navbar-nav">
<li><a href="#option1">Option 1</a></li>
<li><a href="#option2">Option 2</a></li>
<li><a href="#option3">Option 3</a></li>
</ul>
</div>
</div>
</div>
The nav items link to sections on the page, rather than different pages so I need the dropdown to hide on click.
导航项目链接到页面上的部分，而不是不同的页面，所以我需要下拉菜单来隐藏点击。
Whenever I try to toggle the dropdown manually with jQuery, it messes up future functionality of the dropdown toggle button:
每当我尝试使用 jQuery 手动切换下拉菜单时，它都会弄乱下拉切换按钮的未来功能：
$("#navbar li a").click(function(event) {
// check if window is small enough so dropdown is created
$("#navbar-toggle").is(":visible")
$("#nav-collapse").toggle();
});
Is there a better fix for this?
有没有更好的解决方法？

If you wanted to do this without JavaScript you could simply add the data-target and data-toggle to each list item, like so:
如果你想在没有 JavaScript 的情况下做到这一点，你可以简单地将 data-target 和 data-toggle 添加到每个列表项，如下所示：
<li data-toggle="collapse" data-target=".nav-collapse"><a href="#option1">Option 1</a></li>
<li data-toggle="collapse" data-target=".nav-collapse"><a href="#option2">Option 2</a></li>
<li data-toggle="collapse" data-target=".nav-collapse"><a href="#option3">Option 3</a></li>
For the navbar, this really only works in the mobile view mode when there is a toggle button. Strange things happen when the navbar is exposed (the toggle button isn't showing).
对于导航栏，当有切换按钮时，这实际上仅适用于移动视图模式。导航栏暴露时会发生奇怪的事情（切换按钮未显示）。

Change this:
改变这个：
$(document).ready(function () {
$("#navbar li a").click(function(event) {
// check if window is small enough so dropdown is created
$("#navbar-toggle").is(":visible")
$("#nav-collapse").toggle();
});
});
to this:
对此：
$(document).ready(function () {
$("#navbar li a").click(function(event) {
// check if window is small enough so dropdown is created
$("#nav-collapse").removeClass("in").addClass("collapse");
});
});

I don't know why clicking/tapping on a menu item in a menu dropdown in a collapsed navbar doesn't automatically toggle the menu in Bootstrap. There may be a more graceful way to do this, but, here's how I fixed it (using Bootstrap 3.0.3):
我不知道为什么在折叠的导航栏中单击/点击菜单下拉菜单中的菜单项不会自动切换 Bootstrap 中的菜单。可能有一种更优雅的方法来做到这一点，但是，这是我修复它的方法（使用 Bootstrap 3.0.3）：
<li class="visible-xs">
<a href="#" data-toggle="collapse" data-target=".navbar-collapse">Link</a>
</li>
<li class="hidden-xs">
<a href="#">Link</a>
</li>
Basically, there are two versions of the link, one that appears whenever the menu toggle is shown (at browser widths <768px) that will toggle the navbar menu, and one that doesn't collapse it (browser widths >768px). If you don't add that second type, it will show a strange phantom animated horizontal scroll bar when trying to toggle the menu when it is not there.
基本上，有两种版本的链接，一种在显示菜单切换时出现（在浏览器宽度 <768px 时）将切换导航栏菜单，另一种不会折叠它（浏览器宽度 >768px）。如果您不添加第二种类型，当它不存在时尝试切换菜单时，它将显示一个奇怪的幻影动画水平滚动条。

I am new to Bootstrap but with a small changed to the above code it works beautifully now. Remember that when you click on the logo the drop-down menu should close too, that is why I have added navbar-header to it!
我是 Bootstrap 的新手，但对上面的代码做了一些小改动，现在它可以很好地工作了。请记住，当您单击徽标时，下拉菜单也应关闭，这就是我向其中添加导航栏标题的原因！
jQuery(document).ready(function () {
jQuery(".nav a, .navbar-header a").click(function(event) {
// check if window is small enough so dropdown is created
jQuery(".navbar-collapse").removeClass("in").addClass("collapse");
});
});

With Bootstrap 3.3.4 I realized my old way quit working. Updated it to:
使用 Bootstrap 3.3.4，我意识到我的旧方式不再工作。将其更新为：
if ($('div.navbar-collapse').hasClass('in')) {
$('button.navbar-toggle:visible').click();
}
