来自波浪线svg的连续波动画

Question

你好我有一个svg是一个用adobe illustrator构建的波浪线,我正在尝试添加像动画一样的连续波.

我已经尝试过vivus.js并且能够使绘制动画工作但不能连续.

有没有人知道如何开始这样的事情？我不希望有人为我做这个问题,而是指向正确的方向,但如果有人快速回答,我不会反对.

任何答案都可以用于纯粹的css,js或两者兼而有之.

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>

Answer 1

我希望这能帮到您。稍微播放一下这些值，或将SVG波形添加为背景，重复进行并更改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"
     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

Answer 2

除了css技巧,你可以使用带间隔的Math.sin,将它应用于Bezier曲线(循环和连接到属性字符串)并完成.

function anim(){
	document.querySelectorAll('svg circle').forEach((c,i)=>c.setAttribute('cy',50+Math.sin(performance.now()/1000+i)*25))
}
setInterval(anim,20)

<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 0 456 100" style="enable-background:new 0 0 456 100;" xml:space="preserve">
<style type="text/css">
    .st69{fill:none;stroke:#000000;stroke-width:12;stroke-miterlimit:10;}
</style>
    <circle cx="50" cy="50" r="4"  fill="red" />
    <circle cx="100" cy="50" r="4"  fill="red" />
    <circle cx="150" cy="50" r="4"  fill="red" />
    <circle cx="200" cy="50" r="4" fill="red" />
    <circle cx="250" cy="50" r="4"  fill="red" />
    <circle cx="300" cy="50" r="4"  fill="red" />
    <circle cx="350" cy="50" r="4"  fill="red" />
    <circle cx="400" cy="50" r="4" fill="red" />
</svg>
