Jquery menu not working in mobile browser

Question

I have a website, I have used :

http://osvaldas.info/drop-down-navigation-responsive-and-touch-friendly

as my navigation. However everything works, but when i make the browser smaller I try opening the navigation and it doesn't open. after hours of investigation, there is a problem in this Jquery script.

        $(document).ready(function () {
        $('#mobileMenu').append('<div id="nav" role="navigation">' + $('#mainNav').html() + '</div>');
        $('#nav').append('<div style="position:absolute;top:0px; right:0px;"></div>');
        $('#mainNav').html('');
    }); 

any ideas on where I might be going wrong.

#nav is the class that opens the menu, but i need this code on my site but i think i may be missing something.

Answer 1

Javascript to handle click on menu icon:

$(window).on('resize', function() {
    if(jQuery(window).width() < 661) {
        $('#nav').find('.desktopNone').eq(0).unbind('click');
        $('#nav').find('.desktopNone').eq(0).on('click', function() {
            if($('#nav').find('ul').eq(0).css('display') == 'none') {
                $('#nav').find('ul').eq(0).show();
            } else {
                $('#nav').find('ul').eq(0).hide();
            }
        });
    } else {
        $('#nav').find('ul').eq(0).show();
    }
});

CSS to make it looking good:

media="all"
@media only screen and (max-width: 40em)
#nav > ul {
    height: auto;
    display: none;
    position: absolute;
    left: 0;
    right: 0;
    background: #F1F1F1;
    z-index: 100;
}

Answer 2

Instead of body load function use window re size function

$(document).ready(function () {
   $('#mobileMenu').append('<div id="nav" role="navigation">' + $('#mainNav').html() + '</div>');
       $('#nav').append('<div style="position:absolute;top:0px; right:0px;"></div>');
          $('#mainNav').html('');
});
