244143 - Mozilla stops at control with tabIndex="-1"

Status: RESOLVED DUPLICATE of bug 56809

(Core :: Layout: Form Controls, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113

In IE you can prevent TAB from stopping at controls with tabIndex="-1". Mozilla
handles tabIndex="-1" the same way as if tabIndex isn't set, ie it first loops
through all controls with tabIndex set, and the start with then ones with
tabIndex="-1".

I do not know if tabIndex=-1 is an IE-specific trick. I didn't find anything
about it in

http://www.w3.org/TR/REC-html40/interact/forms.html#adef-tabindex

but it is very useful.



Reproducible: Always
Steps to Reproduce:
1. Open http://www.xleverywhere.com/mozilla/tabindex/tabindex.htm
2. Press tab and notice it stops at the 2nd "10"
3.



Expected Results:  
It should have skipped the 2nd "10"

Are there any workarounds?

-1 is an invalid tabindex value per the spec.
http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.11.1

So we don't do what IE does.  It's their weird thing.

I think my URL shows a good example where it is stupid to stop at all form
controls. Therefor, I think that IE has a good solution to this.
