我试图遵循cloneNode部分下的示例
here(文档中第四次出现’cloneNode’).该文件说这是一个草案,所以我想知道这些功能是否与SVG不存在？
这是我的HTML：
<html>
<head>
<script>
var Root=document.documentElement
function clone(){
var G=document.getElementById("groupid")
alert('hi')
var NewG=G.cloneNode(true)
alert('bye')
var move="translate("+0+","+30+")"
NewG.setAttributeNS(null,"transform",move)
Root.appendChild(NewG)
}
clone()
</script>
</head>
<body>
<div style="" width="100px" >
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="200px" viewBox="0 0 1 1" style="fill:purple;stroke:red" id="bigsvg"><?xml version="1.0" encoding="UTF-8" standalone="no"?>

如您所见,警报“再见”不起作用.在此先感谢您的帮助.
解决方法
这似乎比需要的更复杂.从root svg中的pawn路径开始.然后克隆,并附加到root.克隆后要解决的一个重要问题是,您应该更改克隆元素的ID.否则,在处理原始克隆元素时,您将遇到冲突.
试试这个：
