CSS/Jquery - 在 mobile/tab 上查看时的导航下拉菜单

CSS/Jquery - Navigation dropdown when viewing on mobile/tab

我有一个导航栏,在子菜单上有一个下拉悬停,它在桌面上运行良好,但在移动设备上运行不佳,因为它覆盖了所有其他选项卡并且也不起作用在触摸屏上,只要你的手指离开下拉菜单,悬停就会消失。我希望能够单击子菜单上的下拉菜单,然后保持一行。很像移动视图中的导航本身。

Javascript

$(function() {
        var pull        = $('#pull');
            menu        = $('nav .menu');
            menuHeight  = menu.height();

        $(pull).on('click', function(e) {
            e.preventDefault();
            menu.slideToggle();
        });

        $(window).resize(function(){
            var w = $(window).width();
            if(w > 320 && menu.is(':hidden')) {
                menu.removeAttr('style');
            }
        });
    });

首先你需要纠正一些 HTML、css 和 JS 的东西。

1) 我在 ul 之前保留了你的菜单开启标签。

2) 然后禁用 css 菜单悬停在 600 和 320 视图中打开

3) 如果有子菜单,则绑定jquery点击事件。

$(pull).on('click', function(e) {
    e.preventDefault();
    menu.slideToggle();
});

您可以查看下面的 jsFiddle 并与您的进行比较。

我会建议你,如果你是新手,那么使用 bootstrap。这对你有帮助。并将帮助您更快地发展。

否则,如果您想学习,那是很好的尝试。但请记住,总有改进的机会。

为下拉标签添加 id 它有助于获得正确的子菜单

  $('#dropdown_submenu').click(function(){
       $(this).next().toggle();
  });

将此添加到 css

@media only screen and (max-width : 600px) {

     nav ul li:hover > ul {
      display: none; 
    }
   nav ul li > ul{
        background: gray;
      text-align: center;
      border: 0;
      z-index: 100;
    }
}
@media only screen and (max-width : 320px) {

    nav ul li:hover > ul {
      display: none; 

    }
     nav ul li > ul{
        background: gray;
      text-align: center;
      border: 0;
      z-index: 100;
    }

}
