Question

我对响应式导航栏有一个问题，当我为移动视图调整浏览器大小并打开然后关闭菜单按钮，之后使浏览器全屏显示大屏幕视图导航栏将消失对该问题的任何帮助

我需要在向下滚动时添加另一个功能来修复导航栏，但是当在移动设备上滚动菜单时，它看起来很混乱

在我的代码下面（在代码段上）

$(document).ready(function(){
    $(".menu").click(function(){
        $("nav").slideToggle(800);
    })
});

nav{
    width: 100%;
    background: #202c45;
    padding: 0 50px;
    box-sizing: border-box;
}
nav h1{
    margin: 0;
    padding: 0;
    float: left;
    padding-top: 18px;
}

nav h1 a{
    color: #fff;
    text-decoration: none;    

}

nav ul{
    margin: 0;
    padding: 0;
    float: right;

Answer 1

根据您的html结构，您必须将以下代码添加到您的css

@media (min-width:768px){
    nav{
        display: block !important;
    }
}

使用此功能，您无需对html和CSS进行任何更改。

    $(".menu").click(function(){
        $("nav").slideToggle(800);
    })

您还需要在调整窗口大小时更新导航。好心检查。希望这对你有所帮助。刚刚在jquery中进行了更新。

$(document).ready(function(){
    $(".menu").click(function(){
        $("nav").slideToggle(800);
    });
    
    $( window ).resize(function() {
    
      if($(window).width() > 767) {
        $("nav").slideDown(800);
      }
    });
});

nav{
    width: 100%;
    background: #202c45;
    padding: 0 50px;
    box-sizing: border-box;
    display: block
}
nav h1{
    margin: 0;
    padding: 0;
    float: left;
    padding-top: 18px;
}

nav h1 a{
    color: #fff;
    text-decoration: none;    

}

nav ul{
    margin: 0;
    padding: 0;
    float: right;
}

nav ul li{
    list-style: none;
    display: inline-block;
    padding: 20px;
    transition: 0.5s;
    }

nav ul li:hover{

}

nav ul li a{

    text-decoration: none;
}

.responsive-bar{

    display: none;
}

.responsive-bar h3{

    padding: 3px 0;
    float: left;
    color:#fff;
}

请检查下面的代码行，在nav上方添加图片并使标题粘贴。

<强>脚本

$(document).ready(function(){
    $(".menu").click(function(){
        $("nav").slideToggle(800);
        $("nav").toggleClass("fixed_nav");
        $(".responsive-bar").toggleClass("addtop");
    });
}); 


$(window).scroll(function(){
    if($(window).width() > 767) {
        if ($(window).scrollTop() >= 150) {
            $('nav').addClass('fixed-header');
        }
        else {
            $('nav').removeClass('fixed-header');
        }
    }
    else {
        if ($(window).scrollTop() >= 150) {
            $('.responsive-bar').addClass('fixed-header');
        }
        else {
            $('.responsive-bar').removeClass('fixed-header');
        }
    }
});
