1) Are form elements (input, select, textarea) inside a shadow dom
considered when submitting a form?
The Shadow DOM spec doesn't say anything about this. Therefore,
form elements should be in the same node tree.
For example, suppose a <form> element is in the node tree A. In this
case, form elements in node tree B, where A != B, are not considered
at all when submitting the form.
I am not sure I am able to fully interpret your response: do you imply
that an <input> field inside a shadow dom inside a <form>
(diagram:
<form>
|
[shadow root]
|
<input>
)
shall get submitted?
This might pose some backwards incompatibility for tools that
automatically aggregate input values (for e.g. xhr-based submit) by
executing form.querySelectorAll("input, select, textarea"). An input
inside a shadow root (not visible to a querySelectorAll from the outside
world) will get ommited.
Sincerely,
O. Zara
A composed tree shouldn't have any effect on submitting a from.
2) I am having troubles with lifecycle callback of custom elements that
are cloned from within a <template> element. More specifically, nor
createdCallback nor attachedCallback are fired when an element in
question is cloned from template.content or appended to an active
document. Is this a specified behavior? How do I properly initialize
custom elements that "live" inside a <template> ?
Thanks a lot,
sincerely,
Ondrej Zara
