这是一个带有子菜单的菜单代码，不工作子菜单。菜单代码适用于个人电脑和平板电脑，但子菜单不起作用。另外，我希望子菜单在平板电脑中像 Accordion 一样工作。 

$(document).ready(main);

var contador = 1;

function main (){
    $('.menu_bar').click(function(){
        // $('nav').toggle(); Forma Sencilla de aparecer y desaparecer

        if (contador == 1){
            $('nav').animate({
                left: '0'
            });
            contador = 0;
        } else {
            contador = 1;
            $('nav').animate({
                left: '-100%'
            });
        };

    });
};

最佳答案

您可以添加一个新类以在您的菜单中使用“toggleClass”。像这样:

.show_menu_bar {
  left:0;
}

并为动画添加到导航的过渡:

header nav {
 width:100%;
 max-width:1000px;
 background:#024959;
 transition: all ease .4s;
 position: relative;
}

我建议您在 jQuery 上使用方法“on”。您可以阅读它的工作原理 here .

$(document).on('click', '.menu_bar', function() {
    $('nav').toggleClass('show_menu_bar');
});

要使子菜单具有动画效果，请向主菜单按钮添加一个类并再次使用“on()”

$(document).on('click', '.display_submenu', function() {
    $(this).next().slideToggle('fast');
});

子菜单的 CSS:

nav .display_submenu + * {
  position: absolute !important;
  top:100%;
  background: #024959;
}
@media screen and (max-width:800px ) {
  nav .display_submenu + * {
    position: relative !important;
    top:auto;
    background: inherit;
  }
}

您可以看到此示例有效 here .来自墨西哥的问候
