601877 - event listener for the invalid event does not work

Status: RESOLVED WORKSFORME

(Core :: DOM: Events, defect)

Description

[Matt Cosentino]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20101002 Firefox/4.0b7pre
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20101002 Firefox/4.0b7pre

When a form is submitted and an input fails the constraint validation an "invalid" event is fired.  Setting the "oninvalid" attribute on the input works, but setting the "oninvalid" property or adding an event listener for the "invalid" event does not.

Reproducible: Always

There are two parts in this bug report:
 1. HTMLElement has no oninvalid property (nor oninput or onchange, etc.)
 2. addEventListener('invalid') doesn't work

For 1. I will open a bug. But 2. seems to work for me.

I've open bug 618948

>  2. addEventListener('invalid') doesn't work

I'm renaming this bug and will attach a test case.

    For 1. we should do the same as for other onfoo listeners: just add it
    to nsDOMClassInfo.

    We have already bugs open to change the way we register onfoo listeners.

You should see an alert with the message "invalid event" if you press enter in the input element while empty. This should work on trunk.
