我已经做了一些研究,但似乎无法准确找到我要找的东西。我的目标是在我的 JS 应用程序底部有一个导航栏,当用户单击某个按钮时,它会启动一个动画,导航栏从应用程序底部移动到应用程序顶部。以下是我为说明我的意思所做的一些编辑:
after user presses "profile" button, for example
不确定哪个 JS 库可以帮助我解决这个问题,或者是否有代码示例。这里的关键是我不希望它在单击的任何按钮上移动,只有某些按钮。例如,如果用户点击我上面示例中的“图书馆”,我希望它留在底部。
可能有人知道我如何才能做到这一点吗?
编辑:所以我这样做的原因是因为这是一个电子应用程序,我希望一些内容是本地的,而一些内容是远程的。这就是为什么当用户按下“库”时我希望导航栏保持静止。但是,如果用户按下“配置文件”,它将移至顶部,并且“内容”窗口将有点像网络浏览器,因为它将在远程网络服务器上加载页面。我希望这有帮助。感谢您提供所有信息!

最佳答案
您可以使用一些 JS 向您的导航栏添加一个类来制作动画,您可以在单击具有特定 ID 的按钮时添加此类。
下面是演示这一点的片段:
$('#profile').on('click', function(){
toggleNavLocation();
});
function toggleNavLocation() {
$('nav').toggleClass('top');
}
nav {
width:100vw;
height:50px;
background:#000;
bottom: 0;
color:#fff;
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
position: absolute;
}
nav.top {
bottom:calc(100% - 50px);
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
}
li {
display:inline-block;
width:100px;
height:25px;
background:rgba(255,255,255,0.2);
text-align:center;
line-height:25px;
cursor:pointer;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<html>
<body>
<nav>
<ul>
<li id="profile">Profile</li>
<li id="library">Library</li>
</ul>
</nav>
</body>
</html>
如果你不想让它动起来,只是跳到顶部或底部,那么你可以删除所有这些行:
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
这是一个演示这一点的片段:
$('#profile').on('click', function(){
toggleNavLocation();
});
function toggleNavLocation() {
$('nav').toggleClass('top');
}
nav {
width:100vw;
height:50px;
background:#000;
bottom: 0;
color:#fff;
position: absolute;
}
nav.top {
bottom:calc(100% - 50px);
}
li {
display:inline-block;
width:100px;
height:25px;
background:rgba(255,255,255,0.2);
text-align:center;
line-height:25px;
cursor:pointer;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<html>
<body>
<nav>
<ul>
<li id="profile">Profile</li>
<li id="library">Library</li>
</ul>
</nav>
</body>
</html>
这些示例使用了一些 JQuery,但如果您想要纯 JS,您应该能够将它移植到 Vanilla,并在我提供的代码中考虑一下。
