117617 - innerHTML looses newlines

Status: RESOLVED WORKSFORME

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

Description

[Georg Maaß]

The getter part of the innerHTML implementation sometimes looses some newline 
characters. I don't know the conditions which trigger this bug, but there is a 
sample page on the web, where you can see the bug. Because thes page tests for 
the bug before doing any modifications the parts, where the bug aoccures are not 
modified. In this sample the realted Elements are PRE tags. Without modifying 
them the newlines are present, but when reading from innerHTML they go lost. So 
the bug must be in the getter part of innerHTML.

On following page innerHTML fails 2 times:

http://gml-modul.sourceforge.net/cgi-bin/gmL?domain=dhtml-tutorial&webpage=22

The parts, where the bug occures are marked with a bug icon.

This bug was also observed on the old implementation, which used IFRAME tags 
instead of PRE tags with server side inclusion of the content.

This bug is also present in Mozilla 0.9.7

Hm, sounds really like a duplicate of bug 89780. In my case the LF characters are 
dropped. There are no CR characters to drop, because the files are created on a 
Linux system. I don't know what would happen, if line termination is done with CR 
LF, because neither my old Mac editors nor my old Linux editors support that 
format.

So Georg, to dup or not to dup, that is the question :-)

Confirming, but adding dependency...

testcase?

Attachment: The testcase

If the bug is fixed, then the stylesheet sample code should be colored (syntax
hiliting).

With this build the testcase works well:

Mozilla 1.2b
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b) Gecko/20021030

Comment 8

[Georg Maaß]

With this one it works well too

Mozilla 1.3a

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021123

This bug isn't resolved.  I'm attaching a test case to illustrate.  Since the
behavior is completely different, I don't think this is a dupe of 89780, though
it may be related.

Attachment: Create a <select> and get its innerHTML for comparison

Create a <select> control and add newline-separated text to it via
document.write().  Compare the control's innerHTML to the content that was
written into the document.
