150759 - Enter should fire onchange for drop-down listbox changed with arrow keys

Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Jesse Ruderman]

When the user selects an element from a drop-down list using the arrow keys,
Mozilla doesn't fire the onchange event until the user leaves the element.  This
is necessary because web sites often use drop-downs for navigation.  But not all
keyboard users will think to use the Tab key to fire onchange, so Enter should
also work.  Enter should fire onchange for the drop-down (if the drop-down
selection has changed) and then onsubmit for the form.

Better version.  This version doesn't fire onChange multiple times if you hit
enter multiple times.
