288915 - onbeforeunload event is not supported by Camino

Status: RESOLVED WORKSFORME

(Camino Graveyard :: General, enhancement)

Description

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.6) Gecko/20050331 Camino/0.8.3
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.6) Gecko/20050331 Camino/0.8.3

Check the URL above for an example.  A dialog should display when navigating
away from the page (using any method), but not in Camino.  The Firefox version
of this bug is 68215, and has been resolved (the feature was added to Firefox
before 1.0).  Basically, Camino just doesn't support this Javascript trigger.  I
don't know how important this is to the general browsing public, and it's not
part of any official HTML/XHTML spec, but I find it incredibly useful in my web
application programming to make the user interface more friendly and less prone
to human error.

Reproducible: Always

Steps to Reproduce:
1.  Go to the example URL,
http://www.webreference.com/dhtml/diner/beforeunload/bunload4.html
2.  Navigate away from the page using any method--click a link, hit back, close
the window, etc.
3.  Notice the lack of dialog box.

Actual Results:  
No dialog box.

Expected Results:  
Should have displayed a dialog informing the user they're leaving the page, and
are they sure they want to do this.  A trivial example, obviously, but the
feature becomes useful to auto-save long forms or ensure the user knows
information may be lost.
