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.eleme nts.id1
The shorthand form was, in my opinion, a mistake and the elements
collection is standardised.
how can i reference something like this:
<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.get ElementById) {
row = document.getEle mentById('id2') ;
}
if(row) {
/* Now have a reference to the table row. */
}

Hope that helps,

Thank you, it works nicely.

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
