Rails spinoffs - Jan 2008 - Small doubts with clonePosition, Keypress and this

Hello Guys,

I comes to try to clarify some small doubts, I''m trying to create a
function that, if I positioned over this, create a box around the
cell, but I don''t want to alter values of style, I think that a good
way is create a floating table with the same dimensions, to do this, I
found "Position": overlap but says it''s obsolete, then I
found
clonePosition  but couldn''t make it works.

I''m doing this:

var box = new
Element(''div'',{''style'':''border:1px
red''});

Event.observe(document, ''mouseover'', function (event) {
	var element = event.element();
                if (element.tagName == ''TD'') {
	            element.clonePosition(box);
                }
}

Is anything wrong?

Well, I also tried to do the following, staying on the cell if press
SHIFT + CLICK copy the text to clipboard, but this feature doesn''t
works for me directly:

Event.observe(document, ''keypress'', function (event) {
	if (event.keyCode == 42 || event.keyCode == 54) alert("ok");
});

And what happend with javascript "this" value, becouse

Event.observe(document, ''mouseover'', function (event) {}

Is not the same that

<a href="" onmouseover="some(this)">
.....
function some(o) {}

Or how can I handle "this" value with Prototype.

Thk U in advance

Hello Guys..

I''m testing too  with box.absolutize(); but nothing yet, and  when I
compare Event.observe(document, ''mouseover'', function (event)
{} with
function some(o) {} , jeje it''s really not the same one is an event an
other is element in this case.

Thank
