jsfiddle 没有 jQuery 作为外部资源包含在内，添加它可以解决您的问题。
在 JsFiddle 的左侧，单击外部资源，您应该会看到一个空列表。然后，您可以添加代码笔示例具有的以下 2 个外部资源：
//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js
//cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenMax.min.js
您可以通过单击 设置 然后 Javascript.
查看 codepen 中的依赖项
This 分叉了您的代码之一。
您忘记导入 jquery 库和 Tweenmax 库。它们需要在 <HTML> 中导入。
//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js
//cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenMax.min.js
为什么 SVG 动画在 this original CodePen, but not in my copy on JSFiddle 中有效？ 我应该调用 JS 库吗？

jsfiddle 没有 jQuery 作为外部资源包含在内，添加它可以解决您的问题。
在 JsFiddle 的左侧，单击外部资源，您应该会看到一个空列表。然后，您可以添加代码笔示例具有的以下 2 个外部资源：
//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js
//cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenMax.min.js
您可以通过单击 设置 然后 Javascript.
查看 codepen 中的依赖项This 分叉了您的代码之一。
您忘记导入 jquery 库和 Tweenmax 库。它们需要在 <HTML> 中导入。
