Question

我似乎对响应式CSS和JQuery有一个奇怪的问题

当窗口调整为600px
单击hr（图标）以显示Nav
再次点击小时以隐藏导航，并调整窗口大小，导航不可见

如果导航是可见的，然后调整大小＆gt; 600px导航始终可见。

问题是否与jquery代码有关？

    }
}

JQUERY：

$(".icon").click(function() {
    $(".leftmenu .nav").toggle(); 
});

$(".leftmenu .nav ul li > a").click(function() {
    $(".icon:visible").click();
});

Answer 1

该行

$(".leftmenu .nav").toggle();

增加

display: none

第二次点击图标后，

到你的菜单中隐藏它。

使用以下方法将其删除：

$(window).resize(function() {
  $(".leftmenu .nav").css("display", "");
});

Answer 2

要远程触发事件处理程序，请使用trigger()。

$('.icon:visible').trigger('click');

切换关闭时，jquery div不显示
