166349 - Alert box chops off blank spaces.

Status: VERIFIED DUPLICATE of bug 50348

(Core :: DOM: Core & HTML, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1b) Gecko/20020826

Try

alert("Hello,          hello!");

and you'll see that those blank spaces are condensed to one single blank space.
 I don't think this is a good idea.  For the moment, the only work-around is to
use \xA0 like this:

alert("Hello.\xA0\xA0\xA0\xA0\xA0\xA0Hello");

Reproducible: Always

Confirming bug with Mozilla trunk binary 20020828xx on WinNT.

The alert() function is part of the DOM, not core JS Engine.
---> DOM Level 0

Compare bug 50348 - duplicate?
"alert() strips leading and trailing whitespace of parameter"

Why alert() belongs to DOM1?  alert() is a method of "window".  I can't find any
reference of "window" belonging to DOM1.  Correct me if I'm wrong, but please
give me an URL.

DOM0, not DOM1.  DOM0 == "backwards compatible shit in javascript".  See the
component descriptions.

Verified Duplicate.

[e-mail]: thank you for this report; you have 
been cc'ed on the other bug so you can follow progress on this.

For reference, the component descriptions for Bugzilla are at
http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

Note that |window| is an object created by the DOM. JS Engine
deals with lower-level language functionality, such as Number(),
Date(), String(), and RegExp(). JS Engine is independent of the
browser and does not have the objects |window|, |document|, etc.

Those objects, etc., form the "Document Object Model" == DOM

Oh sorry, when I saw the letter "D" of DOM, I immediately thought it's about
Document and thus didn't pay attention to the number "0".  I wonder why it's
called DOM 0.
