Javascript 如何从左侧而不是从顶部滑动导航栏？

Question

提问by PythonEnthusiast

Bootstrap supports toggling a navbar from the top. How can I slide it from the left when the screen-size is small?

Bootstrap 支持从顶部切换导航栏。当屏幕尺寸较小时，如何从左侧滑动它？

For example:

例如：

In the screenshot provided above, when the screen is re-sized, the navbar is toggled and slides down from the top. I rather want that the navbar should slide from the left. How can I achieve this function in Bootstrap?

在上面提供的屏幕截图中，当屏幕重新调整大小时，导航栏会切换并从顶部向下滑动。我宁愿导航栏应该从左侧滑动。如何在 Bootstrap 中实现此功能？

Currently, as per code, the navbar slides from the top. Here is my code:

目前，根据代码，导航栏从顶部滑动。这是我的代码：

<nav class="navbar navbar-site navbar-default" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <button data-target=".navbar-collapse" data-toggle="collapse" class="navbar-toggle" type="button"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button>
            <a href="{% url 'index' %} " class="navbar-brand logo logo-title">
            <span class="logo-icon"><i class="icon icon-search-1 ln-shadow-logo shape-0"></i> </span> <span>Companyname </span> </a> 
        </div>
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav navbar-right">
                {% if user.is_authenticated %}
                    <li class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown"> <span>{{user.first_name}}</span> <i class="icon-user fa"></i> <i class=" icon-down-open-big fa"></i></a>
                        <ul class="dropdown-menu user-menu">
                            <li class="active"><a href="account-home.html"><i class="icon-home"></i> Personal Home </a></li>
                            <li><a href="statements.html"><i class=" icon-money "></i> Payment history </a></li>
                            <li><a href="{% url 'logout' %}"> <i class="glyphicon glyphicon-off"></i> Signout </a></li>
                        </ul>
                    </li>
                {% else %}
                    <li><a href="{% url 'login' %}">Login</a></li>
                    <li><a href="{% url 'signup' %}">Signup</a></li>
                {% endif %}
                <li class="postadd"><a class="btn btn-block btn-border btn-post btn-danger" href="{% url 'post_ad' %}">Post Free Add</a></li>
            </ul>
        </div>

Easy. Change the default behavior from

简单。更改默认行为

<button ... data-toggle="collapse" data-target="#my-navbar-collapse">

to slide-collapsefunctionality which we are going to implement now

到slide-collapse我们现在要实现的功能

<button ... data-toggle="slide-collapse" data-target="#my-navbar-collapse">

Where the menu is contained within divthat has the id my-navbar-collapse. Note that using id instead of class selector will improve the accessibility because bootstrap will append ARIA states (expanded/collapsed) to the menu automatically.

包含divid的菜单所在的位置my-navbar-collapse。请注意，使用 id 而不是类选择器将提高可访问性，因为引导程序会自动将 ARIA 状态（展开/折叠）附加到菜单。

<div id="my-navbar-collapse" class="collapse navbar-collapse">
    <ul class="nav navbar-nav">
        ...
    </ul>
</div>

Class .collapsein bootstrap ensures the menu to be initially hidden.

.collapsebootstrap 中的类确保菜单最初被隐藏。

The code:

编码：

And then paste the following Javascript somewhere in the footer:

然后将以下 Javascript 粘贴到页脚中的某处：

// mobile menu slide from the left
$('[data-toggle="slide-collapse"]').on('click', function() {
    $navMenuCont = $($(this).data('target'));
    $navMenuCont.animate({'width':'toggle'}, 350);
});

And the following CSS properties:

以及以下 CSS 属性：

#my-navbar-collapse {
    position: fixed;
    top: 0;
    left: 0;
    z-index: 1;
    width: 280px; /*example + never use min-width with this solution */
    height: 100%;
}

Some hints:

一些提示：

Good idea is also to make responsive query where menu width would be 100% for smartphones instead of always 280px. It works like a charm.
If you have horizontal menu for desktops, and slider only for smaller devices, you can easily take advantage of @grid-float-breakpointand @grid-float-breakpoint-maxBootstrap LESS variables

好主意也是进行响应式查询，其中智能手机的菜单宽度为 100%，而不是始终为 280px。它就像一个魅力。
如果您有台式机的水平菜单，滑块仅适用于小型设备，可以轻松地利用@grid-float-breakpoint和@grid-float-breakpoint-max引导LESS变量

Bootstrap 4 (update 2019)

Bootstrap 4（2019 年更新）

IMO the simplest way is to override the Bootstrap collapse animation so that it transitions from left to right (width instead of height). Instead of toggling display:blockwhen .collapse.showis used, the Navbar is always display:blockwhich enables you to position as needed and use transitions from both collapsing directions...

IMO 最简单的方法是覆盖 Bootstrap 折叠动画，使其从左到右过渡（宽度而不是高度）。使用导航栏display:block时.collapse.show，不是切换，而是始终display:block使您能够根据需要进行定位并使用从两个折叠方向的过渡...

Open menu: .collapse- .collapsing- .collapse.show
Close menu: .collapse.show- .collapsing.show- .collapse

打开菜单：.collapse- .collapsing-.collapse.show
关闭菜单：.collapse.show- .collapsing.show-.collapse

    .navbar-collapse {
        position: absolute;
        top: 54px;
        left: -100%;
        width: 100%;
        transition: all 0.4s ease;
        display: block;
        opacity: 0.8;
    }
    .navbar-collapse.collapsing {
        height: auto !important;
        left: -100%;
        margin-left: 1px;
        transition: all 0.2s ease;
        opacity: 0.9;
    }
    .navbar-collapse.show {
        margin-left: 100%;
        transition: all 0.2s ease;
        opacity: 1;
    }

Use this for right-to-left sliding:

将此用于从右向左滑动：

HTML :

<div class="nav ">
       <ul>
        <li><a href="#">HOME</a></li>
        <li><a href="#">ABOUT</a></li>
        <li><a href="#">SERVICES</a></li>
        <li><a href="#">CONTACT</a></li>
       </ul>
   </div>

CSS:

CSS：

.nav{
    position: fixed;
    right:0;
    top: 70px;
    width: 250px;
    height: calc(100vh - 70px);
    background-color: #333;
    transform: translateX(100%);
    transition: transform 0.3s ease-in-out;

}
.nav-view{
    transform: translateX(0);
}

JS:

JS：

$(document).ready(function(){
  $('a#click-a').click(function(){
    $('.nav').toggleClass('nav-view');
  });
});

Please refer this CODEPEN. The following important points to note:

请参考这个CODEPEN。需要注意以下要点：

Animate.csslibrary required. Specifically the slideInLeftand the slideOutLeftanimations.
Work with dropdowninstead of the collapsecomponent of Bootstrap.
Set the dropdown-menuelement staticby applying the class position-staticon it.
Leveragethe showclass that is applied on the dropdownelement when the dropdown-menuis shown.
LeverageleftCSS property to carry out the transition. Basically, we'll set left:-100%on .dropdown.show .dropdown-menuand we'll set left:0pxon .dropdown .dropdown-menu

需要Animate.css库。特别是slideInLeft和slideOutLeft动画。
使用下拉菜单而不是Bootstrap的折叠组件。
通过在dropdown-menu元素上static应用类position-static来设置元素。
在显示时利用show应用于dropdown元素的类dropdown-menu。
利用leftCSS 属性进行过渡。基本上，我们将设置left:-100%上.dropdown.show .dropdown-menu，我们将设置left:0px上.dropdown .dropdown-menu

Screenshot:

截屏：

NOTE: You can tryout other animations for the dropdown-menufrom animate.css.

注意：您可以为dropdown-menu来自animate.css 的其他动画试用。

Good Luck...

祝你好运...
