当单击屏幕上的任意位置时，jQuery隐藏引导幻灯片菜单

Question

Made a Fiddle here:
https://jsfiddle.net/r94dq2e4/

I am using twitter bootstap version 3 with a slide in menu from the left when navbar toggle button is clicked.

This is the jQuery code I'm using:

// Nav
(function ($) {
    'use strict';

    // Toggle classes in body for syncing sliding animation with other elements
    $('#bs-example-navbar-collapse-2')
        .on('show.bs.collapse', function (e) {
            $('body').addClass('menu-slider');
        })
        .on('shown.bs.collapse', function (e) {
            $('body').addClass('in');
        })
        .on('hide.bs.collapse', function (e) {
            $('body').removeClass('menu-slider');
        })
        .on('hidden.bs.collapse', function (e) {
            $('body').removeClass('in');
        });

})(jQuery);

This works well and on first click of the navbar toggle button, the menu slides in, when clicked again, the menu slides out. I would like to enhance this functionality in such a way that the menu slides out when the user clicks anywhere on the page except for the menu itself.

This is my HTML for the menu:

Toggle navigation Menu

                       <div class="navbar-collapse collapse" id="bs-example-navbar-collapse-2">    
                           <ul class="nav navbar-nav">
                                <li class="dropdown">   
                                    <a class="dropdown-toggle" data-toggle="dropdown" href="#">Treatments<b class="caret"></b></a>
                                    <ul class="dropdown-menu">
                                        <li><a href="#">Menu Item</span></a></li>

                                    </ul>
                                </li>
                                <li><a href="#">About Us</a></li> 
                                <li><a href="#">Meet the team</a></li> 
                                <li><a href="#">See the results</a></li> 
                                <li><a href="#">Cost</a></li> 
                                <li><a href="#">Information</a></li> 
                            </ul><!-- end navbar-nav -->
                        </div><!-- end navbar-collapse -->
                    </nav><!-- end navbar -->

I have started with the following jQuery code to achieve this. But I would need some help in where to go from here:

/* Nav click outside hide navbar */
    $(document).click(function(e){

    // Check if click was triggered on or within #menu_content
        if( $(e.target).closest("#navbar2").length > 0 ) {
            return false;
        }
        // Otherwise
        // trigger your click function
         $('body').removeClass('menu-slider');
         $('body').removeClass('in');

    });

Thank you

There are 3 things that you need to check in order to see if you should close the menu:

1. The element is not the nav itself ( .nav )
2. The element is not the nav container ( .navbar-cllapse )
3. The element is not a child-element of the nav ( .parents('.nav') )

if (!$(e.target).hasClass('navbar-collapse') && !$(e.target).hasClass('nav') && $(e.target).parents('.nav').length == 0) {
    $('#bs-example-navbar-collapse-2').removeClass('in');
}
