The clientHeight and offsetHeight of the svg element are 0 and undefined in Firefox, but are normal in Chrome. How to get the height of svg?
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<svg id="svg" viewBox="0,0,50,50" version="1.1" xmlns="http://www.w3.org/2000/svg">
<rect x="0.5" y="0.5" rx="3" ry="3" width="49" height="49" fill="transparent" stroke="black" stroke-width="1"/>
<text x="25" y="30" text-anchor="middle" font-size="14px" font-family="Yahei" fill="red">Abc</text>
</svg>
<script>
let a=document.getElementById('svg').clientHeight;
console.log(a);
</script>
</body>
</html>

可以用 getBoundingClientRect().height解决。
具体我没有碰到过，但是可以给你一个思路。火狐浏览器的提示还是人性化的。直接去控制台查看svg高度的定义方式，如果火狐中显示0和undefined请贴出控制台error。如何能给你思路，请采纳谢谢
