(partial) answer... http://www.haskell.org/haskellwiki/Yhc/Javascript/Programmers_guide/Up_from_... in section "12 Getting and setting properties" seems close to what I want. I still don't understand this well enough to use though... t. 2007/12/4, Thomas Hartman :

When I broaden the grep to

tbod

instead, I get a hit for HTMLTableElements.hs.

This has functions

set'tHead, get'tHead

along with various other set/get combos, but only

get'tBodies

-- no set here.

Is there some logic to what gets both a set and a get, and what gets just a get?

Also, is there an easy way for me to manipulate the attributes, for example "height" for a particular tag/dom element?

How about functionality for setting an element's position / dimensions, analogous to setElementPosition / setElementDimensions in mochikit (which I'm using now).

Thanks, thomas.

Grepping around, I see functions for table creation / manipulation in the javascript DOM stuff, but nothing for the tbody tag.

Is this because it's missing from the IRL DOM specification, or a bug, or what? Should I add functionality for creating this tag myself, or is it easier to fix the generated haskell?

I ask because the place where I want to use this javascript from haskell stuff should be making a tbody embedded in a div that is smaller than the tbody; in modern browsers renders as a table with scrollbars.

Thanks, thomas.

Okay I'm beginning to get this. Also, as to my question earlier about where to set styles I see this is in CDOM/Level2/DomUtils.hs I was looking in Level1, and that (you might me privately) is Wrong. All the stuff that matters, and that is being developed is in under Level2. thomas. 2007/12/4, Dimitry Golubovsky :

If IDL says an attribute is readonly then only get. If not, then set and get.

If this is a DOM attribute, use set'height. If this is a style attribute, see below.

Mochikit probably has some wrappers around CSS to work cross browser.

If you would like to manipulate styles directly, use "inlineStyle" function first (see CDOM/Level2/DomUtils.hs), then use setters and getters on the TCSS2Properties object.

inlineStyle inp (set'borderWidth "0px") $ \_ ->

Nice thing about setters, you may chain them together:

inlineStyle inp (set'borderWidth "0px") (set'fontSize "14pt") $ \_ ->

But then you need to remember how different browsers name same attributes (note that EchoCPS2 is not colored correctly in MSIE, while in FF it is green on black - correct coloring).

I wish Mochikit had any IDL specs for their interfaces (or perhaps some XML which with medium amount of pain might be converted to IDL). Is there any?

Thank you.
