Bug 48193 – HTMLFormElement.elements doesn't include fieldsets

• Component: DOM
• Status: RESOLVED FIXED

[Ms2ger (he/him; ⌚ UTC+1/+2)]

Fieldset is a listed element (see $URL). Test: <http://software.hixie.ch/utilities/js/live-dom-viewer/saved/674>

Tested with:

Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.41 Safari/534.7
Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.11 Safari/534.10

[Ms2ger (he/him; ⌚ UTC+1/+2)]

In particular, the test should log "[object HTMLFieldSetElement]" or some such, rather than "undefined".

Patch.

Added filedset and keygen to HTMLFormElement.elements by making them enumeratable.
object element should be listed as well and I will file a separate bug for that.

You should instead just remove this member function entirely. The function inherited from HTMLSelectElement already returns true, there is no need to override.

I don’t think “separate bug will be filed” makes sense in a comment in the test. Maybe you mean we’ll test that with a separate test?

Do the test results match Firefox and/or IE exactly?

Firefox and Opera do list keygen, fieldset and object. I am still testing on IE. Will have the results before committing this patch.
Firefox does not list output element though.

Thank you for the review. I will make the adjustments before committing. Since object elemnt is not as straightforward as keygen and fieldset, I filed https://bugs.webkit.org/show_bug.cgi?id=50179 to fix that.

IE9 Beta does not support keygen element, but it does list fieldset in HTMLFormElement.elements .
