带有子菜单的菜单.PC，平板电脑和电池

这是带有子菜单的菜单代码，并且不使用子菜单。菜单代码，适用于PC和平板电脑，但子菜不起作用。另外，我希望像平板电脑中的Acordion这样的子菜单工作。

$(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%'
            });
        };
    });
};

谢谢。

您可以在菜单中添加一个新类，以使用" toggleclass"。这样：

.show_menu_bar {
  left:0;
}

并为动画添加过渡：

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

我建议您在jQuery上使用" on"方法。您可以在此处阅读它的工作方式。

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

动画子菜单将类添加到主菜单按钮中，然后再次使用"（）"

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

CSS用于子菜单：

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;
  }
}

您可以在此处看到此示例。来自墨西哥的问候
