用于分配INNERHTML并決議為SVG元素的Javascript

我通常使用 javascript 以編程方式創建 SVG，并且它們對于特定元素的給定屬性非常簡單。

但是，我已經創建了一些svg元素，并希望有選擇地將元素從已創建的元素分配給一個全新的元素。我怎樣才能做到這一點？

詳細說明，

const svgns = 'http://www.w3.org/2000/svg'
const data = document.querySelectorAll('.data');
const g = document.createElementNS(svgns,'g');
const svg = document.querySelector('svg')
svg.appendChild(g);
g.innerHTML=data[1]

<svg viewBox="0 0 1280 720">
<path class="data" d="M0,369.7212377116376L42.5,369.7212377116376L85,205.8361201779427L127.5,193.40571206161306M212.5,137.41217543094052L255,137.41217543094052L297.5,153.22714379227432L340,153.22714379227432L382.5,153.22714379227432L425,105.78223870826811L467.5,105.78223870826811L510,89.9672703469343L552.5,153.22714379227432L595,153.22714379227432L637.5,153.22714379227432L680,121.59720706960431L722.5,121.59720706960431L765,105.78223870826811L807.5,58.337333624261966L850,58.337333624261966L892.5,58.337333624261966L935,15.710233471524248L977.5,15.710233471524248L1020,0" fill="none" stroke="black" stroke-width="2px"></path>

</svg>

有了以上，我結束了這個

但我想以這個結束，

你很接近，但你需要使用outerHTML物件 (data[1]) 否則你會得到你所擁有的。

const svgns = 'http://www.w3.org/2000/svg'
const data = document.querySelectorAll('.data');
const g = document.createElementNS(svgns,'g');
const svg = document.querySelector('svg');

svg.appendChild(g);
g.innerHTML=data[1].outerHTML

使用.innerHtml或.outerHtml隱式序列化和反序列化要復制的元素。如果您想保留 DOM 物件（對于非常大的子樹，這實際上可能更慢），請使用Node.cloneNode(deep).

const svgns = 'http://www.w3.org/2000/svg'
const data = document.querySelectorAll('.data');
const g = document.createElementNS(svgns,'g');
const svg = document.querySelector('svg')
svg.appendChild(g);
g.appendChild(data[1].cloneNode(true))

它正在列印 Element 物件，因此您可能需要從該元素中參考所需的屬性...

g.innerHTML=data[1].innerHTML

你不遠，命名空間createElementNS可用于創建 svg 元素。但是要創建另一個就像g使用createElement其余的一樣，基本上就像 html
