try this

$('.sidebar-toggle').on('click', function(){

    if( $('.sidebar-left').length > 0 ) {
        var SideWay = 'left';
        var Sidebar = $('.sidebar-left');
    } else {
        var SideWay = 'right';
        var Sidebar = $('.sidebar-right');
    }
    var animateIt = {};
    var SidebarWidth = Sidebar.css('width');

    if( Sidebar.css('display') == 'none' )
    {
        animateIt[SideWay] = '0';
        Sidebar.fadeIn('fast').animate( animateIt , 400);
    } else {
        animateIt[SideWay] = '-' + SidebarWidth;
        Sidebar.stop().animate( animateIt , 500).fadeOut();
    }

});
