Synopsis
input.focus( )
Description
The focus( ) method
of a form element transfers keyboard focus to that element without
calling the onfocus event handler. That is, it
makes the element active with respect to keyboard navigation and
keyboard input. Thus, if you call focus( ) for a
Text element, any text the user types appears in that text element.
Or, if you call focus( ) for a Button element, the
user can invoke that button from the keyboard.
All form elements except the Hidden element support the
focus( ) method. Unfortunately, not all platforms
support keyboard navigation equally well. In Unix versions of
Netscape, focus( ) is functional only for those
form elements that display text: Text, Textarea, Password, and
FileUpload.
