用javascript制作svg背景动画

我正在添加一个带有js的svg背景，并使用set interval为其旋转设置动画。这在chrome上运行得很好。但是，它不会在任何其他浏览器上显示。有什么想法吗

let i = 0;
setInterval(() => {
    document.body.style.backgroundImage = `url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='100%25'%3E%3Cdefs%3E%3ClinearGradient id='a' gradientUnits='userSpaceOnUse' x1='0' x2='0' y1='0' y2='100%25' gradientTransform='rotate(${i},814,458)'%3E%3Cstop offset='0' stop-color='%230f63ff'/%3E%3Cstop offset='1' stop-color='%23d90fff'/%3E%3C/linearGradient%3E%3Cpattern patternUnits='userSpaceOnUse' id='b' width='504' height='420' x='0' y='0' viewBox='0 0 1080 900'%3E%3Cg fill-opacity='0.15'%3E%3Cpolygon fill='%23444' points='90 150 0 300 180 300'/%3E%3Cpolygon points='90 150 180 0 0 0'/%3E%3Cpolygon fill='%23AAA' points='270 150 360 0 180 0'/%3E%3Cpolygon fill='%23DDD' points='450 150 360 300 540 300'/%3E%3Cpolygon fill='%23999' points='450 150 540 0 360 0'/%3E%3Cpolygon points='630 150 540 300 720 300'/%3E%3Cpolygon fill='%23DDD' points='630 150 720 0 540 0'/%3E%3Cpolygon fill='%23444' points='810 150 720 300 900 300'/%3E%3Cpolygon fill='%23FFF' points='810 150 900 0 720 0'/%3E%3Cpolygon fill='%23DDD' points='990 150 900 300 1080 300'/%3E%3Cpolygon fill='%23444' points='990 150 1080 0 900 0'/%3E%3Cpolygon fill='%23DDD' points='90 450 0 600 180 600'/%3E%3Cpolygon points='90 450 180 300 0 300'/%3E%3Cpolygon fill='%23666' points='270 450 180 600 360 600'/%3E%3Cpolygon fill='%23AAA' points='270 450 360 300 180 300'/%3E%3Cpolygon fill='%23DDD' points='450 450 360 600 540 600'/%3E%3Cpolygon fill='%23999' points='450 450 540 300 360 300'/%3E%3Cpolygon fill='%23999' points='630 450 540 600 720 600'/%3E%3Cpolygon fill='%23FFF' points='630 450 720 300 540 300'/%3E%3Cpolygon points='810 450 720 600 900 600'/%3E%3Cpolygon fill='%23DDD' points='810 450 900 300 720 300'/%3E%3Cpolygon fill='%23AAA' points='990 450 900 600 1080 600'/%3E%3Cpolygon fill='%23444' points='990 450 1080 300 900 300'/%3E%3Cpolygon fill='%23222' points='90 750 0 900 180 900'/%3E%3Cpolygon points='270 750 180 900 360 900'/%3E%3Cpolygon fill='%23DDD' points='270 750 360 600 180 600'/%3E%3Cpolygon points='450 750 540 600 360 600'/%3E%3Cpolygon points='630 750 540 900 720 900'/%3E%3Cpolygon fill='%23444' points='630 750 720 600 540 600'/%3E%3Cpolygon fill='%23AAA' points='810 750 720 900 900 900'/%3E%3Cpolygon fill='%23666' points='810 750 900 600 720 600'/%3E%3Cpolygon fill='%23999' points='990 750 900 900 1080 900'/%3E%3Cpolygon fill='%23999' points='180 0 90 150 270 150'/%3E%3Cpolygon fill='%23444' points='360 0 270 150 450 150'/%3E%3Cpolygon fill='%23FFF' points='540 0 450 150 630 150'/%3E%3Cpolygon points='900 0 810 150 990 150'/%3E%3Cpolygon fill='%23222' points='0 300 -90 450 90 450'/%3E%3Cpolygon fill='%23FFF' points='0 300 90 150 -90 150'/%3E%3Cpolygon fill='%23FFF' points='180 300 90 450 270 450'/%3E%3Cpolygon fill='%23666' points='180 300 270 150 90 150'/%3E%3Cpolygon fill='%23222' points='360 300 270 450 450 450'/%3E%3Cpolygon fill='%23FFF' points='360 300 450 150 270 150'/%3E%3Cpolygon fill='%23444' points='540 300 450 450 630 450'/%3E%3Cpolygon fill='%23222' points='540 300 630 150 450 150'/%3E%3Cpolygon fill='%23AAA' points='720 300 630 450 810 450'/%3E%3Cpolygon fill='%23666' points='720 300 810 150 630 150'/%3E%3Cpolygon fill='%23FFF' points='900 300 810 450 990 450'/%3E%3Cpolygon fill='%23999' points='900 300 990 150 810 150'/%3E%3Cpolygon points='0 600 -90 750 90 750'/%3E%3Cpolygon fill='%23666' points='0 600 90 450 -90 450'/%3E%3Cpolygon fill='%23AAA' points='180 600 90 750 270 750'/%3E%3Cpolygon fill='%23444' points='180 600 270 450 90 450'/%3E%3Cpolygon fill='%23444' points='360 600 270 750 450 750'/%3E%3Cpolygon fill='%23999' points='360 600 450 450 270 450'/%3E%3Cpolygon fill='%23666' points='540 600 630 450 450 450'/%3E%3Cpolygon fill='%23222' points='720 600 630 750 810 750'/%3E%3Cpolygon fill='%23FFF' points='900 600 810 750 990 750'/%3E%3Cpolygon fill='%23222' points='900 600 990 450 810 450'/%3E%3Cpolygon fill='%23DDD' points='0 900 90 750 -90 750'/%3E%3Cpolygon fill='%23444' points='180 900 270 750 90 750'/%3E%3Cpolygon fill='%23FFF' points='360 900 450 750 270 750'/%3E%3Cpolygon fill='%23AAA' points='540 900 630 750 450 750'/%3E%3Cpolygon fill='%23FFF' points='720 900 810 750 630 750'/%3E%3Cpolygon fill='%23222' points='900 900 990 750 810 750'/%3E%3Cpolygon fill='%23222' points='1080 300 990 450 1170 450'/%3E%3Cpolygon fill='%23FFF' points='1080 300 1170 150 990 150'/%3E%3Cpolygon points='1080 600 990 750 1170 750'/%3E%3Cpolygon fill='%23666' points='1080 600 1170 450 990 450'/%3E%3Cpolygon fill='%23DDD' points='1080 900 1170 750 990 750'/%3E%3C/g%3E%3C/pattern%3E%3C/defs%3E%3Crect x='0' y='0' fill='url(%23a)' width='100%25' height='100%25'/%3E%3Crect x='0' y='0' fill='url(%23b)' width='100%25' height='100%25'/%3E%3C/svg%3E")`

从序列化的url数据重新呈现完整图像的时间太长。如果您内联编写SVG并仅设置gradientTransform属性的动画，您可以做得更好。下面的堆栈片段将元素呈现为HTML页面元素的直接子元素

虽然有两种声明式编写动画的方法，但它们都存在兼容性问题：

带有元素的SMIL动画不适用于Edge/IE CSS动画需要实现gradientTransform，这在SVG2中是新的，尚未在所有浏览器中实现。我没有数据，但我可以看到它在Firefox中不起作用 因此，脚本化的变体实际上是您所能做的最好的；但是，您应该使用该方法确保尽可能平滑地运行动画

让start=null； const gradient=document.querySelector'a'； 函数时间戳{ 如果！开始=时间戳； 常数度=时间戳-开始/30%360； setAttribute'gradientTransform'，'rotate${degree}，814458`； window.requestAnimationFramestep； } window.requestAnimationFramestep； 正文{高度：100vh；边距：0；}

你有用于背景的SVG吗？url是SVG，是的，我可以作为img生成一个外部文件，但我不认为我可以在其中达到rotate属性。在这种情况下，使用CSS3动画而不是JS可能更好更容易？我不是这个意思。与其创建复杂的SVG，还可以简化代码——代码在Firefox中工作，只是呈现不一致。
