svg - 如何修复在 Safari 中不起作用的 SVG 动画

Question

不迟于昨天，我设法制作了一个动画 SVG，它可以在 Chrome 中完美运行。我今天尝试在 Safari 中打开它，但动画不工作。有针对这个的解决方法吗？我曾尝试做一些研究，但大多数研究显示 CSS3 和 d:path CSS 方法也不起作用，而且实际上更糟，因为没有任何显示。

这是我的代码

<svg width="1279" height="650" viewBox="0 0 1279 650" xmlns="http://www.w3.org/2000/svg">

Answer 1

I have tried to do some research but most of them show CSS3 and thed:path CSS method does not work either and is actually worse becausenothing shows up.

请参阅browser support d: path动画。
不幸的是，这在指定的浏览器中不起作用，包括 Safari。让我们希望在不久的将来看到更好的支持。

这个答案不会解决您使用 CSS3 路径动画的问题，因为这是不可能的，但它可以使在所有现代浏览器(包括 Safari)中工作的 SVG 动画变得更容易。

Specifying path data: the d property:

For animation, two d property values can only be interpolated smoothlywhen the path data strings contain have the same structure, (i.e.exactly the same number and types of path data commands which are inthe same order). If an animation is specified and the lists of pathdata commands do not have the same structure, then the values must beinterpolated using the discrete animation type.

要满足这些要求，您可以使用这种技术

步骤#1

首先需要得到起始位置的曲线形状:

第二步

然后，通过在矢量编辑器中移动曲线的 anchor ，我们得到曲线的最终形状:

第三步

接下来，我们编写一条命令来为曲线设置动画:

<animate attributeName="d" values="path1;path2;path1" /> , 其中

path1 - 开始时的曲线形状

path2 - 完成曲线形状

正如 @Kaiido 在评论中所说，尽量不要在分号前留出额外的空格
