使用 javascript 创建动画悬停我需要知道什么

Question

要在 http://www.webdesignerdepot.com/ 菜单中创建这样的动画悬停，我需要知道什么？我知道这个菜单是用 javascript 完成的，我毫不怀疑我应该在哪里寻找这样的图标。

Answer 1

如果我是你，我会使用 jQuery，因为看起来这些效果是基于 jQuery hover 事件：

  $(document).ready(function(){

  $('div').hover(
    function(){
     $(this).addClass('active');
    },
    function(){
    $(this).removeClass('active');    
    }
  );

})

您将需要创建 CSS class，我们将其命名为 'active'，然后处理 class

的属性

函数如：

$('div').animate({left:'+=10px'},500);

可能有用：{left:'+=10px'} - 向左移动部分，500 - 毫秒我想它会产生你想要达到的类似效果

Answer 2

您可以将 svg 与 css（过渡动画）一起使用

您可以在这里阅读更多内容：https://css-tricks.com/using-svg/

我复制并修改了他们的示例，并进行了一些转换： https://plnkr.co/edit/MHIL0sHMVWQE9lonA4eh?p=preview'

希望这对您有所帮助:)
