Specifically, it should clarify the behavior of pressing a submit button (or calling submit() method of the input element) in the following cases: (1) <form> - - - {shadow-root} | +-- <input type="submit"> (2) <form> - - - {shadow-root} | | | +-- <content></content> | +-- <input type="submit"> and encapsulation requirements of the following properties of form elements: * HTMLFormElement.elements, length, <getter>(unsigned long), <getter>(DOMString) * HTMLLabelElement.control * HTMLInputElement.form (and others) 89819 1 dglazkov 2013-06-25 15:34:38 +0000 Does this not cover it? http://www.w3.org/TR/shadow-dom/#html-forms 89859 2 yutak 2013-06-26 01:19:01 +0000 Oops, didn't notice that section. However, the current wording is somewhat vague: * "each shadow tree must scope its form elements and form-associated elements" - What does "scope" mean? * "the form submission must continue to work as specified" - What input elements are considered to be sent when the submit button is pressed? For example, <form> - - - {shadow-root} | | | +-- <input type="hidden" name="x" value="1"> | | | +-- <content select="#sub"></content> | +-- <input type="hidden" name="y" value="2"> | +-- <input id="sub" type="submit"> What should be sent if one presses the submit button? "x=1&y=2", "x=1", or "y=2"? What's the form owner of <input name="x">? What about <input name="y">? - In the example (1) above, <input> element's form owner is null, thus pressing the button does nothing; am I correct? 90878 3 dglazkov 2013-07-17 20:21:53 +0000 *** Bug 20320 has been marked as a duplicate of this bug. *** 105136 4 jonas 2014-05-05 23:42:21 +0000 I don't think that <input>s in a Shadow DOM should get any special behavior compared to other <input>s that are not in the document. I.e. I don't think they should submit with a <form> that lives in a document. See my comment in bug 25562 comment 6 for why. That said, I think that we should implement the system described here http://lists.w3.org/Archives/Public/public-webapps/2014JanMar/0448.html And we could even add special features for making it easier to submit <input>s that live in a Shadow DOM. One way to do that would be to add a .formData property on DocumentFragment or ShadowRoot. That way the implementation of .formData on a custom element would simply be function formData() { return this.shadowRoot.formData(); } 120526 5 hayato 2015-05-27 03:22:24 +0000 Moved to https://github.com/w3c/webcomponents/issues/65
