33014 - Strange textarea content update when changed from JavaScript

Status: VERIFIED FIXED

(Core :: Layout: Form Controls, defect, P3)

Description

[Martin Honnen]

I have the following simple form
<FORM NAME="formName">
<INPUT TYPE="button" VALUE="add text"
       ONCLICK="this.form.output.value += new Date().toString() + '\r\n';"
>
<BR>
<TEXTAREA NAME="output" ROWS="25" COLS="80" WRAP="soft"></TEXTAREA>
</FORM>

which should just allow  - by pressing the button - to add a line with the 
current Date repeatedly to the text area. The date is added however there are 
additional lines added every time you press the button so that distances between 
the lines increase steadily. Very strange behaviour. 
Bug is probably related to
http://bugzilla.mozilla.org/show_bug.cgi?id=28623
where others complained about their javascript assigment to text area not 
showing up correctly. 
This is simple DOM level 0 stuff that ought to work without problems.

kin could you take a look? If not maybe it's a buster bug.

Joe--could you look at this and see if it's a block transformation issue?  The 
strings all get added in the proper order but the breaks seem to get messed up 
after the 3rd click.

i put the same comment on another bug (#35463) :

on any HTMLInput object, this.form is undefined anyway. it should reference the
form the input belongs to.

hmmm... maybe i had better open a proper bug report for this .form problem ?

oops, forget about my previous comment. i tested it on another machine and it
worked. the first machine must have something wrong with its installation of Moz.

sorry for the spam.

I just the test case mentioned above, and tried it on windows, linux, and mac
builds ... it looks like this bug is fixed. Martin, reopen this bug if you still
see it.
