Name
TABINDEX — NN n/a IE 4 HTML 4
Synopsis
TABINDEX=integer
Optional
A number that indicates the sequence of this element within the
tabbing order of all focusable elements in the document. Tabbing
order follows a strict set of rules. Elements that have values other
than zero assigned to their TABINDEX
attributes
are first in line when a user starts tabbing in a page. Focus starts
with the element with the lowest TABINDEX
value
and proceeds in order to the highest value, regardless of physical
location on the page or in the document. If two elements have the
same TABINDEX
values, the element that comes
earlier in the document receives focus first. Next come all elements
that either don’t support the TABINDEX
attribute or have the value set to zero. These elements receive focus
in the order in which they appear in the document. Because an
AREA
element cannot be disabled, it always
receives focus in turn, except for special handling in IE 4.
Typically, an AREA
element wired as a link can be
triggered with a press of the spacebar once the element has focus.
Note that the Macintosh user interface does not provide for giving focus to elements other than text input fields. Image map areas cannot be tabbed to on the Mac version of IE 4.
Example
<AREA COORDS="20,30,120,70" HREF="contents.html" TARGET="display" TABINDEX=3>
Value
Any integer from 0 through 32767. In IE 4, setting the TABINDEX
to
-1
causes the element to be skipped in tabbing
order altogether.
Default
None.
