PR: https://github.com/WebReflection/linkedom/pull/315

const data: DocumentFragment = ...
const template = window.document.createElement('template') as HTMLTemplateElement;
template.content.append(data);

 console.log('innerHTML:', template.innerHTML, 'children:',Array.from(template.content.children));  // innerHTML emptyString

not working..

innerHTML output is empty string

 console.log('innerHTML:', template.innerHTML, 'children:',Array.from(template.content.children));

--log result-- innerHTML: children: [ <ref *1> HTMLStyleElement { ownerDocument: HTMLDocument { ownerDocument: null, localName: '#document', nodeType: 9, parentNode: null, [Symbol(next)]: [DocumentType], [Symbol(prev)]: null, [Symbol(private)]: null, [Symbol(end)]: [Object], [Symbol(CustomElements)]: [Object], [Symbol(MutationObserver)]: [Object], [Symbol(mime)]: [Object], [Symbol(doctype)]: [DocumentType], [Symbol(DOMParser)]: [class DOMParser], [Symbol(globals)]: null, [Symbol(image)]: null, [Symbol(upgrade)]: null, [Symbol(EventTarget)]: [DOMEventTarget] }, localName: 'style', nodeType: 1, parentNode: DocumentFragment { ownerDocument: [HTMLDocument], localName: '#document-fragment', nodeType: 11, parentNode: null, [Symbol(next)]: [Circular *1], [Symbol(prev)]: null, [Symbol(private)]: [HTMLTemplateElement], [Symbol(end)]: [Object] }, [Symbol(next)]: Attr { ownerDocument: [HTMLDocument], localName: 'id', nodeType: 2, parentNode: null, ownerElement: [Circular *1], name: 'id', [Symbol(next)]: [Attr], [Symbol(prev)]: [Circular *1], [Symbol(value)]: 'KQykvzSaQPUDomNDyYpuZNdcxkWCkvHtGvVujfjH-style', [Symbol(changed)]: false }, [Symbol(prev)]: DocumentFragment { ownerDocument: [HTMLDocument], localName: '#document-fragment', nodeType: 11, parentNode: null, [Symbol(next)]: [Circular *1], [Symbol(prev)]: null, [Symbol(private)]: [HTMLTemplateElement], [Symbol(end)]: [Object] }, [Symbol(private)]: null, [Symbol(end)]: { nodeType: -1, ownerDocument: [HTMLDocument], parentNode: null, [Symbol(next)]: [HTMLElement], [Symbol(prev)]: [Attr], [Symbol(start)]: [Circular *1] }, ... ]

I was thus treated with innerHTML.

• template.innerHTM; .. template.content

But I think it needs to be fixed

[WebReflection]

so template.innerHTML is empty but childrens are in there? I don't understand much around this issue, sorry ... please provide examples and expectations in a readable format, thanks!

After appending the child element to the HTML Template Element's content If you do innerHTML, it is normal to output the contents of the child element, but it is not output in linkedom.
