Posted from: 203.218.234.217 43273 1 henry.fai.hang.chan 2010-12-11 11:38:53 +0000 Statement 1: "If the [tabindex attribute] value is a negative integer The user agent must allow the element to be focused, but should not allow the element to be reached using sequential focus navigation." Statement 2: "The tabIndex IDL attribute must reflect the value of the tabindex content attribute. Its default value is 0 for elements that are focusable and −1 for elements that are not focusable." contradiction? it would be better if non-focusable elements had an tabIndex IDL attribute as NULL instead: NULL: cannot be focused (and cannot be in document.activeElement) NEGATIVE: can be focused, not in sequence 0: can be focused, append to end of sequence POSITIVE: can be focused, start of sequence this better corresponds to the current behavior of Opera and firefox. 43274 2 937 henry.fai.hang.chan 2010-12-11 11:45:50 +0000 Created attachment 937 Testcase of current implementations and reason why the tabindex default for non-focusables should not be -1 43275 3 henry.fai.hang.chan 2010-12-11 11:48:07 +0000 sorry, forgot to add: in testcase, click on the top two dives, and an alert will show the document.activeElement. 44124 4 ian 2011-01-11 07:20:45 +0000 The tabindex content attribute and the tabindex IDL attribute are distinct; there's no contradiction, it just means that if you try to fetch the tabindex IDL attribute when its corresponding content attribute is not set, you don't get a useful value. The attached test only tests the content attribute, not the IDL attribute. 45681 5 ian 2011-02-16 09:33:22 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
