what's wrong in here?!!?

[yoyoyo]

hi guys,
i'm developing a function that having as argument the branch of a
structured tree returns the tree showing only the parents of that
branch..

the function that doesn't work is the following:

function openParents(id) {
if (document.getEl ementById(id).c lassName!="root ") {
var par=document.ge tElementById(id ).parentNode;
par.nextSibling .style.display= "block";
openParents(par .id)
}
}

this function should recall itself in order to open all the ancestors..
i really cannot understand why it doesn't work!

(the argument given is the id of a branch)

thank u to everyone!
teo

You cannot display the next sibling if the parent is display:none;.

Colouring the siblings, and displaying just the parents works great (IE):

=============== ===============
<style>
div {display:none;}
</style>
<script type="text/javascript">
function openParents(id) {
if (document.getEl ementById(id).c lassName!="root ") {
var par=document.ge tElementById(id ).parentNode;
par.style.displ ay="block";
par.nextSibling .style.backgrou ndColor="red";
openParents(par .id)
}
}
</script>

<div class='root'>
root<br>
<div id='d1'>
d1<br>
<div id='d2'>
d2<br>
<div id='d3'>
d3<br>
<div id='d4'>
d4<br>
<div id='d5'>
d5<br>
</div><span>1</span>
</div><span>2</span>
</div><span>3</span>
</div><span>4</span>
</div><span>5</span>
</div><span>6</span>
<button onclick='openPa rents("d5")'>sh ow</button>
=============== =============== ======

Re: what's wrong in here?!!?

hey, thank u for your raply! i thought u were never going to help me!
actually i didn't understood so well what u said to me..
u said that i cannot make somethingto be displayed:block if it is
contained inside something with display:none..

well, i don't agre..
i mean: of course i won't see anything inside an element with
display:bock, but as soon as i make the "container".dis play:block i
will also see everything inside..

don't u think so?

i'm just trying to start from the branches to make them visible to
arrive till the root node, as i thinku understood..

The facts show you are wrong:

<div style='display: none;'>
Suppressed
<div style='display: block;'>
Can you read this? No way!
</div>
</div>

Did you test it out before not agreeing?

That is not my name.

Good thought, if you don't follow Netiquette you won't get much help.
The asking has to follow customs of the asking game.

Re: what's wrong in here?!!?

i tried to be polite, i thanked u for your help, why should u continue
to tell me "don't use this" "don't say that" "hey is not my name"..
??? i really don'T understand u..

anyway, of course i've tried before to post..in the function i'm
developing i'm setting display:block from the last branch till the
first root..as u can see from the code i've postes, that function
recall itself..

of course if u just set display:block on the branch and not on the root
u cannot see anything..but is u then continue and set block also to the
previous root u'll see evrything!

You only displayed the siblings, not the parents.

This is my last answer if you don't follow the NG's rules.

You haven't tried hard enough to be polite.

You've been asked to show us the courtesy of posting in a form
that suggests that you have some respect for the people who are
considering offering help.

It shouldn't matter whether or not you understand *why* we ask
you to do this. As a matter of courtesy, you should comply.
