javascript - 来自波浪线 svg 的连续波浪动画

Question

你好，我有一个 svg，它是用 adobe illustrator 构建的波浪线，我正在尝试向它添加连续的波浪状动画。

我已经尝试过 vivus.js 并且能够让绘图动画正常工作但不是连续的。

有没有人知道如何开始这样的事情？我不希望有人为我解决问题，而是为我指明正确的方向，但如果有人能快速回答我并不反对。

任何答案都可以工作，无论是纯 css、js 还是两者兼而有之。

这是svg

<svg id="wave" version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     viewBox="0 0 456.7 39.9" style="enable-background:new 0 0 456.7 39.9;" xml:space="preserve">
<style type="text/css">
    .st69{fill:none;stroke:#000000;stroke-width:12;stroke-miterlimit:10;}
</style>
    <path class="st69" d="M4.2,33.2c0.1-0.1,7-6.9,15.9-13.8C27.7,13.7,38.7,6,47.5,6c7.5,0,14,6.6,20.3,12.9l0.4,0.4

希望对您有所帮助。稍微调整一下值或添加 SVG 波形作为背景，重复它并更改 background-position。

@keyframes wave {
  0% { 
    left: -80px; 
  }
  100% { 
    left: 0; 
  }
}

.container {
  width: 100px;
  overflow: hidden;
}
.container svg {
  position: relative;
  left: -50px;
  width: 200px;
  animation: wave 2s linear infinite;
}

<div class="container">
<svg id="wave" version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
