动画的目的是填充背景颜色作为加载电池。在我看来，解决方案似乎是苹果渐变动画，显示为正在加载。但在当前的 SVG 中，当属性 offset="0%"

将代码更改为这样
<linearGradient id="fromzero" x1="0">
<stop offset="50%" stop-color="#4c7eaf"></stop>
<stop offset="50%" stop-color="#828282"></stop>
<animate attributeName="x1" dur="5s" from="-100%" to="100%" repeatCount="indefinite" />
</linearGradient>
使渐变将背景颜色分割为两种颜色，并将其从 -100% 移动到 100%，从而可以从 0% 到 100%，同时给出完全相同的效果。
我现在还添加了您想要的动画。它是通过点击 svg 元素触发的。
这是一个Fiddle结果
希望这有帮助
关于css - SVG <animate> 从 0 的偏移量不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33231088/
