javascript - 从右侧而不是左侧切换菜单

Question

我有一个可以从左侧切换的菜单，但我需要能够从右侧切换。不确定这是否可以从 jQuery 触发，或者可以在 CSS 中完成。当它应该只垂直滚动时，它也会在切换导航中水平滚动。

<div id="wrapper">
<!-- Sidebar -->
<div id="sidebar-wrapper">
    <ul class="sidebar-nav">
        <li class="sidebar-brand"> <a href="#">
                    Entertainment
                </a>

        </li>
        <div class="container">
            <div class="row">
                <div class="col-md-3">
                    <div class="thumbnail">
                        <div class="caption">
                             info
                    </div>
                </div>
            </div>
        </div>
</div>
<div id="page-content-wrapper">
    <div class="container-fluid">
        <nav class="navbar navbar-default" role="navigation">
            <div class="container-fluid">
                <!-- Brand and toggle get grouped for better mobile display -->
                <div class="">
                    <ul class="nav navbar-nav navbar-left">
                        <li>
                            <img src="logo.png" height="50">
                        </li>
                    </ul>
                </div>
                <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                    <ul class="nav navbar-nav navbar-right">
                        <li><a href="" height="30"></a>

                        </li>
                    </ul>
                </div>
            </div>
        </nav> <a href="#menu-toggle" class="btn btn-default" id="menu-toggle">Toggle Menu</a>

    </div>
</div>
<!-- /#page-content-wrapper -->

真的很简单，您只需将所有为左侧边栏创建空间的 CSS 规则移动到右侧即可。真的就是这样。

我也将此添加到您的侧边栏包装器 overflow-x: hidden; 以在触发菜单时停止显示水平滚动条。

$("#menu-toggle").click(function (e) {
    e.preventDefault();
    $("#wrapper").toggleClass("toggled");
});

#menu-toggle {
    float: right;
}
#wrapper {
    padding-right: 0;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}
#wrapper.toggled {
    padding-right: 250px;
}
#sidebar-wrapper {
    z-index: 1000;
    position: fixed;
    right: 250px;
    width: 0;
    height: 100%;
    margin-right: -250px;
    overflow-x: hidden;
    background: #000;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}
#wrapper.toggled #sidebar-wrapper {
    width: 250px;
}
#page-content-wrapper {
    width: 100%;
    position: absolute;
    padding: 15px;
}
#wrapper.toggled #page-content-wrapper {
    position: absolute;
    margin-left: -250px;
}
/* Sidebar Styles */
 .sidebar-nav {
    position: absolute;
    top: 0;
    width: 250px;
    margin: 0;
    padding: 0;
    list-style: none;
}
.sidebar-nav li {
    text-indent: 20px;
    line-height: 40px;
    padding-right: 17%;
}
.sidebar-nav li a {
    display: block;
    text-decoration: none;
    color: #999999;
}
.sidebar-nav li a:hover {
    text-decoration: none;
    color: #fff;
    background: rgba(255, 255, 255, 0.2);
}
.sidebar-nav li a:active, .sidebar-nav li a:focus {
    text-decoration: none;
}
.sidebar-nav > .sidebar-brand {
    height: 65px;
    font-size: 18px;
    line-height: 60px;
}
.sidebar-nav > .sidebar-brand a {
    color: #999999;
}
.sidebar-nav > .sidebar-brand a:hover {
    color: #fff;
    background: none;
}
@media(min-width:768px) {
    #wrapper {
        padding-right: 250px;
    }
    #wrapper.toggled {
        padding-right: 0;
    }
    #sidebar-wrapper {
        width: 250px;
    }
    #wrapper.toggled #sidebar-wrapper {
        width: 0;
    }
    #page-content-wrapper {
        padding: 20px;
        position: relative;
    }
    #wrapper.toggled #page-content-wrapper {
        position: relative;
        margin-left: 0;
    }
}
