Dynamic HTML: The Definitive Reference

Name

TABINDEX — NN n/a IE n/a 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.

Although this attribute is not yet implemented in browsers, the expected behavior is that when a LABEL element receives focus, the focus shifts automatically to the associated INPUT element.

Example

<LABEL FOR="stateEntry" TABINDEX=3>State:</LABEL>

Value

Any integer from 0 through 32767.

Default

None.
