Как закрыть меню js?

var vertical = document.querySelectorAll('.outer-nav a');
        
        
        for (var i = 0; i < vertical.length; i++) {
            
        vertical[i].addEventListener(clickevent, function( ev ) {
        if( classie.has( perspectivewrapper1, 'animate') ) {           
            ev.stopPropagation();
            ev.preventDefault();
            contentwrapper1.style.top = '0px';
            document.body.scrollTop = document.documentElement.scrollTop = docscroll;
            classie.remove( perspectivewrapper1, 'modalview' );
            classie.remove( perspectivewrapper1, 'animate' );
            var linker = this;
            setTimeout( function() { document.location.href = linker.href; }, 25 );
        }
        });
        }
