referencing a <tr> object

Hi,

if i have this code: <form><input type=text name="id1"></form> then with
javascript i can reference this with this.form.id1, how can i reference
something like this:

<table>
<tr name="id2">
..
..
</table>

?

That works because form controls with name and id attributes are usually
made available as properties of a FORM element. However, I think it's
preferable to use the elements collection to reference form controls:

this.form.elements.id1

The shorthand form was, in my opinion, a mistake and the elements
collection is standardised.

<table>
<tr name="id2">


You shouldn't be able to. Table rows, like the vast majority of
elements, do not have name attributes. They do have id attributes,
though. You can then use the getElementById method to obtain a reference:

<tr id="id2">
var row = null;

if(document.getElementById) {
row = document.getElementById('id2');
}
if(row) {
/* Now have a reference to the table row. */
}

[snip]

Hope that helps,
Mike

The problem is that in Mozilla the rows when appearing/disappearing
display strangely, and making more and more space ... strange. Any
experience with that? (in IE it works fine)

I am attaching you the full code so somebody can check - the text at the
end of the page when sqitching the scrollbar gets more and more pushed
down the page...

tnx,
Greg

<html>
<head>
<script language="JavaScript" type="text/javascript">
function getOther(sel,fld){
if (sel.selectedIndex==sel.options.length-1) fld.disabled=false; else
fld.disabled=true;
var row1 = null;
var row2 = null;
var row3 = null;

if(document.getElementById) {
row1 = document.getElementById('id1');
row2 = document.getElementById('id2');
row3 = document.getElementById('id3');
}
if(row1) {
row1.style.display =
(sel.selectedIndex==sel.options.length-1)?"inline":"none";
}
if(row2) {
row2.style.display =
(sel.selectedIndex==sel.options.length-1)?"inline":"none";
}
if(row3) {
row3.style.display =
(sel.selectedIndex==sel.options.length-1)?"inline":"none";
}
}
</script>
</head>

Assign "", not "inline", to the display property to fix that.

Some more changes I suggest for your script:

function getOther(sel, fld) {
var lastOpt = sel.selectedIndex == sel.options.length - 1;
fld.disabled = !lastOpt;
if (document.getElementById) {
var rows = [
document.getElementById('id1'),
document.getElementById('id2'),
document.getElementById('id3')
];
var disp = lastOpt? "" : "none";
for (var i=0; i<rows.length; i++) {
if (rows[i] && rows[i].style) {
rows[i].style.display = disp;
}
}
}
}
